But also like a normal teenager, she's apparently embarrassed to be seen with her parents, as first lady Michelle Obama revealed in an interview with Entertainment Tonight. Just another day for the first kid of the United States.Transgender activist What makes her powerful: Jennings made her first TV appearance back in 2007, when she was interviewed by Barbara Walters for being a six-year-old transgender girl, one of the youngest cases of someone already transitioning.

And with nearly 20 million Instagram followers herself, her popularity is undeniable.Basketball player What makes him powerful: Even before he graduated from Kansas last year, people called Wiggins the next LeBron James.

He played all 82 games of the season, averaging 16.9 points and 4.6 rebounds per game.Musician What makes him powerful: Over the past couple of years, Bieber's reputation has taken a bit of a tumble, thanks to a string of fights with paparazzi, pot-smoking allegations, and a DUI arrest, not to mention taking a hefty dose of mockery over his Calvin Klein photo shoot. Still, as of November he's the highest-paid celebrity under 30, and still manages to maintain a good sense of humor about himself, making each of his sticky situations, if nothing else, great marketing.Founder of Oculus VR What makes him powerful: Last year, Luckey sold Oculus VR — his virtual reality startup that creates headsets like the Oculus Rift — to Facebook for a solid $2 billion. Not only did the deal turn the 22-year-old into a billionaire, but the headset he created has changed how many people experience video games by making users feel completely immersed in the game.

In addition to offering disappearing photos and videos, it has added a new feature called Discover, which plays video clips from ESPN, CNN, and other content partners.

Fans love her as she interacts with them directly and demonstrates a new way of keeping it real as a celebrity.Basketball player What makes him powerful: Though Oklahoma City Thunder forward Durant missed most of the 2014-15 season due to injury, he's still one of the most dominant players in the NBA.

Basically, any other team would be willing to pay top dollar to have him.Fashion moguls What makes them powerful: Mary-Kate and Ashley Olsen no longer rock matching overalls; these days, they turn heads on the red carpet as bona-fide fashion moguls. The elusive sisters helm two powerful fashion houses — The Row and Elizabeth & James — and are worth a combined $300 million. They founded luxury line The Row in 2004, which not only brings in millions of dollars per year, but cemented the twins' place as capable and respected designers. Mary-Kate and Ashley aren't coasting on their success either: They oversee every detail for both lines, from fabric choices to runway venues.Film producer What makes her powerful: Ellison is a rockstar in Hollywood. Breaking out of the shadow of her father, former Oracle CEO Larry Ellison, she stormed head first into the film industry and owns a successful film production company Annapurna Pictures.

His team, the Cleveland Cavaliers, won 20 more games than they did without him last year. During their first season without James, the Miami Heat won 18 fewer games than they did with him last year. Wherever he goes, he takes 50-win seasons with him. You can't say that about anyone else in the league.CEO of Facebook What makes him powerful: Zuckerberg has built the largest social network ever, with over 1 billion users, and from WhatsApp to Oculus VR, he has overseen a number of huge Facebook acquisitions in the past year or so. His current net worth is nearly $35 billion, making him one of just three people who have more billions under their belt than years lived.Supreme leader of North Korea What makes him powerful: Upon his father's death in 2011, Kim was thrust into power, taking control of North Korea overnight. Kim was appointed marshal in 2012, the country's highest military rank, and caused international controversy by continuing the country's weapons testing. He isn't the most favorably viewed leader in the world, but it's hard to deny his influence. He can snap his fingers and have anyone — whether that's family or North Korean officials — executed.Musician What makes her powerful: There's a reason she's called Queen Bey: At the end of 2013, the former Destiny's Child frontwoman waged a war against retailers like Amazon and Target by refusing to let them stock her self-titled album and, just to spite them, secretly released it overnight on iTunes, causing a momentary crash of the e-store. After winning three Grammys this year, Beyoncé has a lot to teach people — as evidenced by a new course at the University of Illinois at Chicago, called Beyoncé: Critical Feminist Perspectives and U.S. Black Womanhood.Reality TV star and media mogul What makes her powerful: It's undeniable — Kardashian West is everywhere.

CEO of Yelp What makes him powerful: As the CEO of crowd-sourced review site Yelp, Stoppelman has a reported net worth over $222 million. However, he joined the $1 club in 2013 when he and Yelp's COO Geoff Donaker announced that they would be taking a yearly base salary of only a dollar. Stoppelman also takes a hands-on approach to his work, and has written over a thousand Yelp reviews himself. Musician and producer What makes him powerful: It's likely that no one will ever love Kanye as much as Kanye loves Kanye, but he undoubtedly has loyal fans and a prominent place in the music industry. Yeezus, which dropped in 2013, topped the charts and was considered by many to be the best album of the year. He's got a new album in the works, and made his fashion debut in February with a show at New York Fashion Week, where he shared his collaboration with Adidas. Though the line garnered much criticism, it demonstrated West's ability to easily break into new industries. CEO of Square What makes him powerful: Back in 2006, Dorsey co-founded Twitter alongside Biz Stone, Noah Glass, and Evan Williams — he even sent out the very first tweet. Though he stepped down as Twitter's CEO in 2008, Dorsey stayed on as chairman of the board, and drives the bulk of his wealth — currently at $2.4 billion — from his 4% stake in the company. These days, Dorsey focuses the majority of his time on Square, a mobile payment app that lets business owners accept credit card payments through a smartphone attachment. CEO of Yahoo What makes her powerful: Mayer runs one of the most powerful tech companies in the world, and earns the wages to match: Her total compensation package, which includes cash and stock, was $42 million in 2014 — up 69% from the year before.

He headed into 2015 strong, with three movies in the works.Co-founder of Google What makes him powerful: Brin is one of the geniuses behind Google.

Today, the company continues to dominate search, makes a ton of money with ads, and is leading a number of other innovative projects, including Google Glass.

SpaceX launched the first commercial satellite into orbit and is under agreement with NASA to resupply the International Space Station.US Senator What makes him powerful: Cruz became Texas' junior senator in 2012, making him the first Hispanic or Cuban person from the state to serve in the Senate. However, in a short time he went from being the GOP's ultimate conservative purist to one of the most despised men in the Senate, provoking the federal government shutdown in 2013. He also staged a 21-hour faux filibuster to defund Obamacare, during which he famously read Green Eggs and Ham. Cruz continues to work his way up the political ranks, and announced in March that he's running for president in 2016. COO of Facebook What makes her powerful: Sheryl Sandberg is credited with bringing adult supervision to Facebook as its COO. One former Facebook employee said that, thanks to Sandberg, Facebook went from a frat house to a real company. Sandberg is also one of the world's first self-made billionaire women.

With an estimated net worth of $15.3 billion, he's one of the richest people in tech. In fact, Li comes in at No. 62 on Forbes' worldwide billionaires list and ranks fifth in China. And as the CEO of China's top search engine, Baidu, Li's like the Larry Page of Asia.Co-founder of LinkedIn What makes him powerful: Hoffman was a user experience architect at Apple in the mid-'90s — a job which ended up being the launching point for an incredibly successful venture into entrepreneurship.

Abramovich also owns a large stake in steel titan Evraz, which is expected to IPO this year after postponing in December. Author What makes her powerful: Even though the Harry Potter series has long since ended, the legacy lives on, and there's no denying Rowling's continued influence in the world of literature and pop culture. She also became the first billionaire author, and is still cashing in on the boy wizard 17 years later. She retained the digital rights to her novels, rather than signing them over to her publisher, and launched an online store so she can sell the e-books directly to readers. The Pottermore site allows Rowling to reap 100% of sales. Since Harry Potter, Rowling has written two adult novels, The Casual Vacancy and The Cuckoo's Calling, which both became instant bestsellers. She's also returning to the wizarding world, writing the screenplay for a Harry Potter spinoff starring Eddie Redmayne. The film, Fantastic Beasts and Where to Find Them, will be out next year. Executive Chairman of Alibaba Group What makes him powerful: Last year, Ma's e-commerce company Alibaba went public, garnering the largest IPO in history at $25 billion.

Shaw to start Amazon, which became one of the few startups that didn't get wiped out by the dot-com bust, and which now sells nearly $80 billion worth of goods per year. Today, Bezos is worth nearly $39 billion. He bought The Washington Post for $250 million in 2013, and is also the founder of Blue Origin, a new company that's beginning to test space flights. Disclosure: Jeff Bezos is an investor in Business Insider.Governor of New Jersey What makes him powerful: Chris Christie — who's served as the governor of New Jersey since 2010 — came under fire in January of 2014 when a couple of his top aides allegedly closed lanes on the George Washington Bridge, causing a major traffic jam in Fort Lee, New Jersey, the hometown of one of Christie's political opponents. Christie isn't letting the controversy, now referred to as Bridgegate, hold him back though — he's a potential GOP candidate for the 2016 presidential race. President of the United States What makes him powerful: POTUS is in charge of the most powerful nation in the world. Now in his last year in office, he's begun shaping the legacy he'll leave behind at the end of his second term.

He recently told a group of middle schoolers that after the presidency I'll go back to doing the kinds of work that I was doing before, just trying to find ways to help people... That's the kind of work that I really love to do.CEO of Netflix What makes him powerful: There's no doubt that Netflix is killing it lately, with original series House of Cards winning two Golden Globes and four Emmys. Orange Is the New Black holds its own as well, taking home three Emmys from an impressive 12 nominations. And with nearly 60 million subscribers, the streaming service shows no signs of slowing down. In fact, Hastings is so confident in Netflix's future, he believes the service can expand globally within the next two years while still remaining profitable. The numbers support this, too: In the first quarter of 2015, Netflix earned $1.57 billion, 24% more than the same quarter last year.

Not to mention he also commands a fortune of over $3 billion.Prime Minister of Australia What makes him powerful: Prime minister of the country down under since 2013, Abbott has been making big changes since day one. He elevated two women to the federal cabinet, in order to give women more power in Australian government, and repealed the Carbon Tax on fossil fuels, making Australia the first country to ever repeal a carbon tax. His budget plan may not be the most popular, but he has overseen and signed free trade agreements with Japan, South Korea, and China.Chairman of Reliance Industries Limited What makes him powerful: The richest man in India, Ambani is worth an estimated $20.1 billion.

She's been chancellor for longer than anyone in modern history and remains overwhelmingly popular. Germans want her to run for a fourth term. She's got power both at home and abroad. She's one of the most formidable people to stand up to Putin and she's famously defended German interests during the euro zone debt crisis. She's managed to maintain record low unemployment levels and keep the economy afloat. Nothing important in Europe gets done without her say-so, whether that's a good thing or not, and she's often called the most powerful woman in the world.President of China What makes him powerful: Jinping has become the most powerful Chinese leader in decades. As commander of one of the world's fastest-rising superpowers, he's shown a readiness to adopt a degree of change — as shown by his decision to loosen the one-child policy, his promises of economic reform, and a relaxation of restrictions on the rights of migrant workers. But he also stands firmly by China's system of government, saying that the Community Party is the only model proven to work for China.President of Russia What makes him powerful: As the president of Russia, there's no doubt Putin commands a large stake of the world's power.

Now in his fourth term as prime minister, Netanyahu recently announced that he plans to run for an unprecedented fifth term in the next election.Founder and president of Fast Retailing What makes him powerful: The richest man in Japan, Fast Retailing founder Yanai is worth $22.3 billion.

But she's already shown a powerful command over the markets when comments she's made since her appointment have caused stocks to climb or tumble within minutes.CEO of Ford What makes him powerful: Mulally, in conjunction with Bill Ford, famously turned around Ford without accepting government handouts — a feat so impressive that he became a leading candidate to take over at Microsoft, despite his lack of high-tech chops. Ford has gone from posting record multibillion-dollar losses in 2006 when he took the helm, to having one of its best years ever in 2013. Revenue for the first quarter of 2015 was $33.9 billion — it's a slight miss, but analysts predict that this will be the low point for Ford's earnings this year.Founder of Oracle What makes him powerful: Ellison shocked the business world last year by stepping down as CEO of Oracle, the database software company he founded. The billionaire — worth an impressive $53.8 billion — stayed on as Oracle's chairman and chief technology officer, however.

Called the nation's most avid trophy-home buyer, he's all but taken over entire neighborhoods in Malibu and the Lake Tahoe area, and bought the entire Hawaiian island of Lanai.

Leader of the Catholic church What makes him powerful: Since becoming the first non-European pontiff in 1,300 years, the Argentina-born pope developed a platform that criticizes the idolatry of money; beseeches politicians to guarantee all citizens work, education, and healthcare; and calls on rich people to share their wealth. He's well-liked, partly because he's not afraid to admit he's not perfect.
