Killian lunged, his arm extending into a molten spear. Tony barely dodged, twisting mid-air as he fired a barrage of repulsors.
Killian caught one blast with his bare hand and grinned. "I told you, Stark. You can't win."
Tony smirked. "Oh yeah? Watch me."
With a quick command to J.A.R.V.I.S., the external arc reactor on his back detached and shot toward Killian.
Killian caught it—exactly as Tony predicted.
The second Killian's fingers curled around the device, Tony activated its overload sequence.
The arc reactor exploded in a controlled EMP blast, shutting down every Extremis enhancement in Killian's body.
The self-healing stopped. The heat drained from his veins.
Killian staggered.
Tony delivered the final blow—a repulsor blast straight to his now very human chest.
Killian collapsed.
The flames around them grew hotter. The rig was falling apart.
Tony scooped Amii into his arms and launched off the burning platform.
Behind them, the entire structure exploded in a massive fireball.
