10 DC Characters Weaker Than Superman Who Could (In Theory) Kill Him

6. Parasite

Parasite is another moniker that has been utilised by several individuals in the comic books but, as a general rule, they all have the same powers.

The character has the ability to temporarily absorb the energy, knowledge and super-powers of another being by touch and has utilised this ability against Superman on numerous occasions quite effectively and, in theory, if he was given the chance to absorb all of Superman's energies and powers, he could drain him of his life force entirely and, ultimately, kill the Kryptonian.

Again, however, he is another character whom Superman should really not have had any trouble with. At base level, Parasite possesses no enhanced physical statistics - no superspeed, no superstrength, no real durability to speak of etc - and he can't fly, so Superman should be able to defeat him from afar with ease. But that's not to say that Parasite doesn't have the means to kill him in the right circumstances, because he certainly does.
