obviously there are spoilers in the comments, I commented what most of my ocs would do

Phantom would join the Yiga clan lol
K’horr would speedrun it and then proceed to bully random common enemies with whatever torture chambers he can build
Denny would just build random ahh stuff

John would beat it if he had two brute weapons
Triangle empower would probably join the Yiga clan
Double piramid would go to ganondorf and create a black hole next to him
Square empower would not even defeat a flux construct lmao
Rectangle empower would help defeat the monster forces
Trapezoid empower would join the zonia research team
Oval empower would die to a few gloom hands

I don't play Zelda lol

I've never played or seen gameplay of it so i dont know

Redi could probably beat it, but he’d probably need his army to help fight the final boss since he doesn’t have the master sword
Sticktator would probably join the Yiga Clan lmao
Banisher could just go straight to ganondorf and banish him
Portal core could just fly off the great sky island and commit war crimes against bokoblins
Johnny would probably make it off the great sky island but join the zonai research team, then probably get killed by some gloom hands

If the Faron is still their in TOTK, the hunter would probably settle, their, living off of lizalfoes tails
