Doctor Doomsday is a prominent villain in the Amalgam Comics universe (itself a fictional merging between DC and Marvel) - he is a mixture of Marvel's Doctor Doom and DC's Doomsday and is very powerful as well as one of the most recurring characters in the series. Doctor Doomsday is portrayed as a muscular Doctor Doom with spikes on his bio-armor and seeks to conquer the Amalgam Universe - being referred to by some in Amalgam Comics as a being something akin to evil incarnate.
