M.O.D.O.K.

"I have evolved far beyond what I once was. Suffice it to say, you took everything from me. I shall do the same to you."

- M.O.D.O.K. to Iron Man

Mental/Mobile/Mechanized Organism Designed Only for Killing (M.O.D.O.K.) is an enhanced form taken on by Aldrich Killian after his death.

Biography
After his death, it was later revealed that Aldrich Killian's consciousness had been 'downloaded' by A.I.M. prior to his physical death and uploaded into a new, enhanced form.

After Iron Man defeated him in combat, he attempted to survive by uploading his consciousness into the network of Stark Industries, but Iron Man willingly sacrifices the network (and, therefore, Stark Industries itself), destroying Killian for good.
