Even though neither are really "rip-offs", there are some uncanny similarities between Marvel's Man-Thing and DC's Swamp Thing. I hesitate calling Swamp Thing a rip-off of Man-Thing (specfically the Alex Olsen version, as in the original), since the time difference between which the two characters were created was like 2 months.
