One-Winged Angel Kirby, or OWAK for short, was the second boss to be fought in Destroy the Godmodder 2. He was created when Kirby, who was summoned to the field previously, swallowed 02, the secret final boss of Kirby 64: The Crystal Shards. His body was invulnerable to all attack, but his weak point was his large red eye, which could be attacked. If OWAK wasn't killed in six turns, he would wipe the field entirely.
OWAK retroactively dropped the Broken Halo as a Spoil of War upon death. Kirby was resummoned afterwards and lived a happy life for the rest of the game until he mutated into One-Winged Angel Kirby Soul during Act 3.
