Okay, I have some problems judging this guy. Like, the final video - he needs to power up to reach that level? Looks that way, but I could be wrong. Also, is his durability consistent between all videos (ie, if he DOES power up for the final video, is his durability still the same in the first two videos or does that improve as well)? Speed in the first two videos IS hard to judge - some nebulous level of 'crosses short distances in a blink and attacks faster than the eye can see'. Bullet timer? Maybe.
I can't really figure out more, though, until I find out if his final vid against Guytaro is something he can just jump to, or if he needs to jack himself up to do this (talks about 'finishing his score' - musical, based on the other stuff - before he starts moving at truly redonkulous speeds, blowing up vast sections of stony road with missed strikes, fighting in the middle of gigantic explosions, etc).
