NUKE CUT OFF JOHN WALKER'S LEFT ARM AND LEG WITH ODIN'S OWN SPEAR — AND WALKER REFUSED ANY CYBORG REPLACEMENT!

The Featured Fact

During the Siege of Asgard, Walker and the Mighty Avengers raced Norman Osborn's Thunderbolts to the Asgardian armoury to keep Odin's spear, Gungnir, out of enemy hands. In Thunderbolts #142 (2010), the super-soldier Nuke — fighting as Scourge — got there with the spear first and used it to sever Walker's left arm and left leg in a single ambush.

Walker survived, and the government thanked him with a desk: he became warden of the Raft, the super-prison, working from a wheelchair with a plain prosthetic arm. Stark-grade replacements existed all around him, and he turned them down on principle — he would not let the state rebuild him into a cyborg like the man who had crippled him.

The limbs eventually came back by the strangest route on his file. In Dark Avengers #184–185, stranded in an alternate world, an alternate Scarlet Witch used a Venom symbiote as surgical thread and regrew Walker's arm and leg whole — and Walker, staring at his restored hand, was appalled before he was grateful.

Why It's Obscure

One spear took two limbs in Asgard; pride kept the replacements off for years.

2010

The ambush — Thunderbolts #142 puts Gungnir in Nuke's hands and Walker's arm and leg on the Asgardian ground in the same motion.

The warden

The Raft's new boss — From Thunderbolts #144 onward Walker runs the super-prison from a wheelchair, prosthetic arm on display, inmates very much included.

The refusal

Nothing cybernetic — Offered advanced prostheses, Walker chose simple hardware rather than resemble Nuke, the cyborg super-soldier who maimed him.

The regrowth

Symbiote surgery — Dark Avengers #185 restores both limbs with living alien tissue, a cure Walker greets with horror before acceptance.
