I do have some thoughts on these two applications. Specifically, Ichiban has Strengths that would better fit as Powers, and a lot of what he can do in his sheet encapsulates things that everyone can do in the World of Light, or things that are a result of many of its elements working on video game logic.

How would Essence of Mayhem work? I see that it assumes that once the first hit lands, the rest of them are guaranteed. That means the enemy is essentially helpless. Does it occur in its own sort of pocket dimension like it does in game while time is frozen on the outside, does time just freeze around the attack while it's being delivered, or does time not freeze and the attack is just invincible? This is an issue I myself haven't solved with Tora's Chain Attack, which is part of why I haven't used it.

RPG nut is a lot all in one. Wound Ignore and Inventory can both be Strengths in their own right. The other stuff seems like it should be less on Ichiban and more on the world. In this world there's lots of food that heals by its own merit because that's just what it does. Certain weapons, abilities, attacks, etc can all apply buffs and debuffs, and everyone can get their weapons upgraded by blacksmiths because that's what they do. For the downsides, basically everyone has an unwritten MP and stamina. Everyone is vulnerable to status ailments

Poundmates should probably be a Power, unless it's literally "Ichiban knows how to call people on his phone, and he's bizarrely good at convincing them to drop what they're doing and come to him as fast as they can"

If Hello Work, Mobile Edition means he can magically and instantly change gear, attributes, and abilities, then that should be a Power.

For Ganondorf I don't have much to say really. Dark Magic should be a Power. Conversely, having just Warlock Fist as a whole Power feels a little underwhelming. If individual moves are Powers, it'll take a lot to build up even his basic moveset.
