How to kill Meta-Humans

So, I have recently been watching ComicsExplaoned series of "How to Un-Alive Superheroes" in which he attempts to kill superheroes in creative ways/the most efficient ways. So, my task for you is as follows.

Kill the persons character who posted before you, first efficiently; then as creatively as you can within your own characters abilities. You only have to kill one, and try not to copy someone else's answer if you happen upon the same person. I can't stop you from doing so; but it ruins the sport of things. But if you can't think of another way to kill a certain character; I'll understand if you're answer is the same as someone else's. your target?

Blake, the Jersey Devil

Shoot him in the head. Grapple Infernus out of his hands then throw it like a trident into his chest.

Knightfall

Have Madame Mudd cover him in mud and then bury him miles under earth. Use Aqua-lita to bring him close to her, then turn into mud to suffocate him within her body.

Madame Mudd.
