Damn, i need to jump in to clarify something
Goku SSB:UT Aura have 3 EE sources, Hakai, Time Power, and Universe Tree's EE Aura, it passively inducing all 3 types of EE at the same time, because literally, all these 3 powers can passive EE via energy, especially UT's
energy which stated coming into contact with it going to get you
erased. There are also passive Power Null in the Aura from Time Power, aside from Subjective Reality.
Anyway, i don't care if Kratos win this match or not, but saying Goku somehow refrain himself from EE Kratos or any other opponents is bullshit, not only in Heroes he is far more serious, but also literally in this mode he went out of his way to destroy Fu in-verse, his SR didn't even make Fu stronger so the argument that "Goku want to fight strong opponent so his SR going to make that wish come true" went out of the window, he went out of his way to blast Fu to kingdom come, oh wait, Fu got destroyed hard, no kingdom come for him
