Origin

Centuries ago on Earth-88194 the man who was to become Terror Inc. killed a gruesome demon. Of course, by doing this he was cursed.

Terror

His body began to decay and three spikes began to grew on each chin. On the plus side he also got the demon's ability to merge the limbs of others with his own body. He began to call himself Shreck.

Much later he somehow crossed over to Earth-616 and began to call himself Terror, and started a detective agency.

Powers

Terror Inc. has the ability to replace body parts with parts or organs taken from others, a process which he must continuously do since he is constantly decaying.

Any bodypart he assimilates will immediately start to decay.

He also gains memories and eventual skills or super-powers from any bodypart he assimilates. It is not necessary that the bodyparts he assimilates is human, he could add wings or a tail to his body if he wanted. Terror has even replaced his head with another persons to gain their knowledge and memories.

Since his body is dead he do not require to eat, sleep or breathe and doesn't feel pain. He can continue to function even if he is reduced to a skeletal state, or to just his head. He can even survive without a body at all. In his MAX series he was dismembered and dunked in acid but survived as a black ooze that was able to inhabit other bodies.

The spikes on his chins are part of the curse of the demon he slayed. If removed they will grow back. The current (MAX) version of Terror doesn't have these spikes.

Additionally, since being alive several centuries Terror has aquired all sorts of skills and is an excellent marksman and detective, and proficent with most conventional weapons.
