"It is my honor to launch and begin the 2016 Republican National Hungry for Power Games."

So Stephen Colbert proclaimed when he snuck onstage at the Republican National Convention on Sunday, dressed as Caesar Flickerman from TheHunger Games.

WATCH: Stephen Colbert Dares Donald Trump to Appear as a Guest on 'The Late Show'

Before being escorted off, Colbert did manage to squeeze in a Donald Trump diss, shouting, "Look, I know I'm not supposed to be up here. Let's be honest, neither is Donald Trump."

It's unclear whether the Late Show host actually crashed the RNC. In the video, the arena is empty and the convention doesn't kick off until Monday, plus, Colbert is set to film segments for his show from Cleveland, Ohio, all week.

"At the center of power at the RNC," he tweeted alongside a photo of him in costume, complete with a blue wig and painted-on blue eyebrows.

"We don't wanna wait another 24 hours, especially with the Trump campaign," Colbert told ET on Friday of why it is important to do his convention coverage live. "Because 24 hours later, he's going to say something totally different."

Colbert will also take his act to the Democratic National Convention in Philadelphia next week, but he predicts that the Republicans will offer him more opportunity for the antics we've come to know and love him for.

"The Democratic Convention might be easier to prep for than the Republican Convention, because even the Republicans don't know what's going to happen at the Republican Convention," he joked. "Seriously, they said that Tim Tebow was going to be speaking and then next day he said, 'No, I'm not.' I hope Tim will come on my show. Tim, I've just booked you on my show."

"On one side, you've got an extremely cautious candidate who doesn't want to do anything out of the ordinary and on the other side, you have a giant orange manatee that is constantly screaming, 'Please harpoon me!'" Colbert concluded.

Meanwhile, tensions have turned up in the race for the White House. Hear the three epic words Clinton used to slam Trump on Twitter -- and find out how she nearly broke the Internet -- in the video below.
