Okay. So I first saw this animation before seeing the YouTube video about Sigma from Overwatch. And I gotta say, Troll face is more interesting than Sigma.
This is just from how I feel about both characters as I type this review.
The character Sigma feels like your standard Scientist who became insane with power. He can manipulate gravity around him. And he has a bit of a split personality thing that makes him evil. Or at least a prime candidate for Talon terrorist operations. ...I just don't see much with this guy. Other than looking cool. (Or I'm just miss-judging Sigma because I have never played Overwatch before.)
Now with Trollface here, I think he is a serious villain. Sure he looks silly and creepy with that huge stupid smile. But he has mastered all the laws of cartoon physics itself. Therefore he can outmaneuver any contingency plan created by super scientist Rich Sanchez. He can bend reality to his will. Therefore any direct punch from One Punch Man will never budge Trollface. And when Trollface says, "It's all an illusion." He's also talking about Plot armor and the power of friendship. How they are all just strings of the puppeteer. Not to mention that Trollface is an icon born of the internet itself. Making him almost as powerful as Micky Mouse. (More or less.)
Again. These are just my thoughts when looking at this animation in loop. So epic!
