Gates Oltman
Character profile
Personality: His human feelings have been completely eliminated, leaving only a doll that carries out missions for NOA.
The army's anti-psychiccer cyborg, Gates. His grudge against Keith for killing his wife and daughter let him retain his human spirit despite cyborgization.
Because his emotions were unable to be separated from the computer*, Gates suffered a terminal rejection of his mechanical body while on-route to the battle with NOA. Afterwards, he was stored in the old NOA's headquarters.
After establishing Neo NOA, Carlo picked Gates' body up out of storage and remade him as an anti-army cyborg.
Gates, now called Alpha, was reborn as NOA's newest weapon, stripped of all his memories and even his name.

*T/N: I honestly couldn't parse this sentence completely, but I think the idea is that his human feelings caused a rejection of his cyborg body.
It's interesting that PF1 was never specific about who killed Tina and Cheryl and generally points it away from Keith, but 2012 just has Keith do it personally.
