Voiding got pulled two times what-
Anyway, analysis.
Offense power wise, CTLR is an absolute MENACE. Yes Voiding has time power to amplify his attacks and all but CTLR as AOE, good range and some immobilization/incapaciting attacks. Let's put aside the nuke stuff, since that would create at best a draw and way too much casualties for this silly tournament.
The only problem is that CTLR has barely any capabilities defensively. Which isn't really a problem in practically : he can regen from barely anything and has more than enough tools to keep Voiding at range.
IF IT WASN'T FOR TEMPO ABILITIES.
Halt, Star, Dive, those 3 are abilities that could turn the balance literally instantly.
Assuming Voiding uses his abilities instantly (which he SHOULD), he could freeze time and do at least enough damage to put CTLR in a weaken state.
And then it's basically attacking CTLR over and over until he gives up, since Voiding has nothing to completely destroy him entirely.
And if CTLR tries to zone him out, Half would render any projectiles useless.
So yeah, unless Voiding is going for the clip, he wins.
