The gaming world knows him as "Ninja," the biggest name in the world of Fornite.

But now, Tyler Blevins, who's making a killing of a career streaming the popular video game on Amazon's Twitch, has announced that he'll be switching streaming platforms over to Microsoft's Mixer.

Ninja announced the move via his social media channels, which shook up the streaming world on Thursday. 

With over 14.7 million followers on his Twitch account, Ninja more than doubled the next closest streamer.

"So, I have been holding on to this for quite some time, and I'm just super excited to let everyone know. Obviously, I'll be streaming on Mixer full-time now, and I'm honestly at a loss for words," Blevins said in a video on Twitter. "I'm freaking out in the best of ways. I feel like I'm going to get back to the streaming roots, and that's what it's all about."

Mixer rebranded from the name Beam in 2017 after being launched a year before. Up until their deal with Ninja, the platform struggled to compete with the two streaming giants in Twitch and YouTube.

"We've loved watching Ninja on Twitch over the years and are proud of all that he's accomplished for himself and his family, and the gaming community," Twitch said in a statement. "We wish him the best of luck in his future endeavours."

Ninja just wrapped up his appearance at the inaugural Fortnite World Cup Finals where he competed in two tournaments and did colour commentary.

The 26-year-old professional gamer is said to make over $500,000 a month from streaming Fortnite on his channel.

TSN's Marissa Roberto, who hosts various e-sports shows, says Twitch shouldn't suffer from losing its most popular star to much, but knows Microsoft chalked up a huge victory. 

 "It feels like a massive power shift, but Twitch will be totally fine. They still make bank on many of their partners, but this was a huge power move for Mixer and Ninja."

To summarize the move, Roberto summed it up best.

"This is Amazon vs Microsoft."

"Twitch has been top dog for a long time now. This is huge for the streaming world, but Ninja has increased Mixers legitimacy tenfold. It’s amazing news for so many streamers who have felt the need to stay with Twitch because they don’t want to lose their current audience.

"Ninja’s bringing with legions of followers and new accounts who will be looking for other streamers to watch on the platform."
