Mobile Suit Gundam Thunderbolt December Sky ✓

We see this horrifically realized in the Psycho Zaku. It is a towering junk golem, barely holding together, fueled by the literal blood and nervous system of its pilot. When Daryl plugs in, the machine becomes his body. The tragedy is that the closer he gets to "perfection" as a pilot, the further he drifts from being a man. He wins the battle but loses himself in the machinery.

Set in Universal Century 0079, the story takes place in the "Thunderbolt Sector"—a treacherous shoal zone filled with colony wreckage and intense electrical discharge. mobile suit gundam thunderbolt december sky
