@Satsuki:
That and I have no idea how "sticky grapes" can be made any more powerful.
Like this.
Just being able to make bigger ones (or smaller ones) would be a game changer. They could even inflate on impact.
Like if a giant boulder is about to fall on someone, and then he throws out a giant cushy ball that sticks to the ground and cushions the falling rocks. like whenever Luffy does a balloon move. Or if he makes a big one he can stick any enemy in one shot and they'll be hard pressed to move.
Also the ability to make more of them without hurting himself. Or different properties. If he could make them smooth and slick instead of sticky, or explode, or hold items in them, there's all sorts of trap and bowling pssibilities. Getting sniping capability.
If he wasn't utter trash person, he could be Usopp.
But really, entirely with the properties he has now, just making them bigger would get nuts fast.
@Cyclone_Baroness:
Hmm. I wonder how Ojiro can improve. He was told to be more creative. But he's still just a martial arts dude with a beefy tail.
His is a lot harder.
Quirk
Tail (尻尾 Shippo?): Mashirao's Quirk gives him a strong, sturdy tail. He is incredibly adept at using it, having demonstrated creative abilities, such as whipping it down against the ground to give himself a speed boost.
If its really JUST tail, then using it to grab things and break block with judo and do acrobatics could be his limit. Learning to make it super hard would overlap a lot with Kirishima I think, and being able to randomly grow more would just be like Shoji's arm growing.
What if he can make it longer though? Like, really long, and really fast, like a bullet?
Or, revise his look entirely and add a shell to his back and add some armor to the tail it to make it more of an Ankylosaurus thing? He's big enough it would be an okay look on him.
Okay, basically his upgrade is to take his normal tail and turn it into basically a scorpion or a dinosaur or add a fun turret to it or something.
