ok, given the Speed equal of this match and that Goku's Aura can't bypass Sonic's due to the latter being conceptual, this is my take:
Sonic:
- Haxes that can one shot Goku like Info type 2, Concept type 1
- An explosive Aura to attack and push Goku away if he comes too close
- Can escape Goku's BFR with his Superior range
- Invulnerability so that Goku's AP advantage is not much relevant even with his Explossive Aura
- Purification and emphatic manip to purify Goku's Emotions and make him not want to fight anymore
- Due to Chaos Energy's Conceptual nature, Goku can't really affect it to hax it, Sonic himself however he can
i guess that is about it for the relevant stuff for this match
as for Goku:
- the non Aura passive version of his Existence and Non Existence erasures could erase Sonic, since it wouldn't need to travel the aura to reach him
- his time stops and manipulation scale to 2 temporal dimensions, bypassing Sonic's resistances, so he could just stop Sonic in time to finish him
- More layered Fate manipulation to make himself win, altho i don't remember if it can still affect acau type 4 beings, also isn't passive
- Subjective reality to just.....wish Sonic away
My vote? eeeehhh, i would like more discussion about which of Goku's wincons are IC for him to use, and maybe i forgot some, i dunno, would also like more discussion in general
