Oh yeah, the person that's using Ultra Ego & Satsui no Hado on top of the True Devil Gene the user is having has access to Shin Satsui no Hado & Oni(the strongest variant of Satsui no Hado).

Is this based on the Ultra Vegito forms Goku and Vegeta took? Or is this based on something else?

^ It's something else actually. I'm only borrowing the known forms & techniques from Street Fighter, Tekken, & well DB

Power of Nothingness > Satsui No Hado

MUI > UE

Angel > Devil

Goku > Vegeta

Considering that power of nothingness seems to counter evil energies (psycho power and satsui no hado are the same apparently), I could see it easily dealing with Shin Hado. We don’t know how much stronger Oni is in comparison to Akuma. But he fights similar to Gouken which suggests similarities between the 2 power wise. And nothing is a direct counter to the hado so I think it’ll be enough for Goku to win.

^ We only see Gouken negating base Satsui in SF4 but personally, I think MUI's speed can help a lot in this matchup before the destructive user evolves any further to Shin or Oni.

^^ Speaking of that, True Ultra Instinct is confirmed to be weaker than MUI since Whis stated himself that MUI is the strongest technique he has in his arsenal so yeah, MUI > UE unfortunately.

We see Ryu overpower an amped M.Bison (or Vega or Balrog depending on where your from). Bison uses psycho power. It runs on fear which was rampant even after the black moons were shut down. And it has actually been stated the satsui no hado and paycho power are the same or come from the same energy. So an amped satsui no hado has been overpowered by the power of nothingness. And Ryu is relatively new user with it. Imagine what Goku could do with it, given he’s a genius fighter.

Shit! I forgot to clarify that when I put "A person" on both choices of the polls, I meant to say users in general.

Tho, it would be nice to see Goku doing a Hadoken when Ryu gives away his own ki to the Saiyan when he gets access to Power of Nothingness tbh.
