THE SUB-MARINER 4EVER!!!
DEATH TO NAMOR!!!
This one is weird, Dormammu should be able to trap his mind in some illusion or other, but given Morgana killed him and he didn't stay dead I'm not sure even big D could put him down for ever. I see Dormamu getting a BFR or mindtrap win, but in a scenario I can see Bob eventually finding a way to do some real damage.
