Eddie Schmitt had once worked for the Biotechno Corporation under Mr. Daigo, doing cybernetic research. He was later hired by the Defense Department for government work in the same field. He had helped Dr. Tine with his cyborg projects inlcuding 8-man, but Eddie suddenly disappeared with a number of sensetive research files. When we finally see Schmitt personally, we see that he has changed. Using the same research files he had stolen, he converted himself into a biocomputer, storing all the cybernetic files in his system and controlling all the complicated machinery in Tony's secret hideout.
Eddie constantly has to refit Tony with new cyborg parts to replace the ones that are damaged by the Cybomechamine, and at Tony's request, he converts Daigo into a cyborg. Schmitt also suggested trying to capture 8-Man to use his cyborg brain, but before he is able to do so, O'Connor throws Tony into the computer, destroying it and Eddie.
