It is, I can point to specific appearances Toad made and put those moves into a hypothetical fighting game character from SMB2, NSMB, 3D World, and even a puzzle game.
You mean be generally useless can jump and sometimes able to lift things. And in the NMB games grab items?
I can't do that with Jr., for instance everyone wants him to use the paintbrush but what could it even do? All Jr. really did in Sunshine was impersonate Mario and draw graffiti. He didn't draw enemies on walls that came to life or erase things out of existence. He was simply a vandal that did nothing but pollute everything and pin blame on Mario.
What can the paint brush do.
First off before I go down , let me remind you that the paint brush can act as a sword.
Well it can open portals through time and space, that he himself and others can access alowing him to combine potential sword combo's with time and space abilities, and he seems to be quite fast. A very interesting long/Close range swords man.

Next
He can create things with his paint brush Create things with his paint brush and use it as other types of weaponry. Sheild, projectives stuff like that. While generally having on over all painting theme.

Lastly
He is BOWSER JR. He already has a potential 2 movesets out of that , his dad or his dad's shit. And since bowser has adopted more wrestling moves, he can be a younger more mobile version of that stuff,

4, 4 moves sets. Using what he has available and that is by myself, imagine the move sets I could come up with if I were sakurai and had a team of people.
