There was a British (I think?) TV show called “misfits” that was about some teenagers getting superpowers. One episode they fought against somebody that could control milk and laughed at him for his power - until he murdered them all by using the milk from their breakfast to stop their hearts. Great show in my memory.
Everyone’s laughing until the immortal guy is suddenly braindead.

Don’t let this distract you from the fact that Bungie Gum has the properties of both rubber and gum.
Hisoka from HunterxHunter comes to mind.
And then there’s Misfits

sounds like Parahumans/Worm to me
