Comics

Not sure with snowflake but yeah probably some sort of Ice based powers, or if Marvel was cool they'd make them the equivalent of DC's Snowflame(who is awesome)

Safespace could create forcefields but only if they were actively using them to protect people

Or even give it some humor! What if it was a closeted hero who had a rivalry with Mayhem Magnet? They have to learn from a Trump-monk at the top of a mountain that magnets stop working if you put them in water. So they embrace their identity as a genderFLUID hero, douse the magnets, destroy the dipolar menace, and save the day?

They start the climb in full Juggalo makeup which the reluctantly have to remove after learning the secrets of magnets
