What powers does your character have that makes it strong

Astro has basically every single weapon possible in his arsenal (weakness is that he’s just a slime without them)

We're talking without any material weapons.

mostly just intelect but also: turning into water(a puddle spesificly), a radiation beam(a small one at that) and able to explode(does not hurt)

ok

But if you can do magic that counts

There's no thing that fits for mine
