For Jingle, all I can think of is it makes him a good musician.
For Stride, easily a speedster word.
For Sciamachy, since it has to do with shadow boxing, I was thinking something like melee from a distance.
For Descriptive, all I can think of is changing the physical appearance of something.
For Neo, there's the Matrix dude and the chick from RWBY.

Too bad we can't have more than 1. I'm gonna go with Stride. If he had his epiphany when he was 13 and he's 23 now, with practice every day, how much control would he have over his speed, how fast would he top out, and would speeds passing terminal velocity have negative effects?
