Mobile Suit Gundam Thunderbolt

Side 4, or Moore, was destroyed by the Zeon forces and is now a "Thunderbolt Sector" filled with floating debris. The Moore Brotherhood, made up of survivors who have lost their homeland, launches an operation to eliminate Zeon's Living Dead Division which now occupies the sector. Pilot Io Fleming of the Moore Brotherhood is shot down in battle by Daryl Lorenz, a Zeon ace sniper, but manages to escape. After killing an enemy pilot and stealing his mobile suit, Io taunts Daryl by sneering at his prosthetic legs. Daryl swears to seek revenge on Io, who has killed his ally and mocked him and his comrades.
