Bloodtype arrived in Vanity City as the hero Mr. America. He was teamed up with his wife Liberty Lass, who later became the villain Death-Doll
. The husband-and-wife team soon were in a terrible accident, and were partially reconstructed by the government. This unbalanced Bloodtype, and he became a psychotic vigilante.
At a bank robbery staged by the Piper
to keep his daughter from being murdered, he encountered Bloodtype. Bloodtype brutally beat him, and prepared to kill him. Aztek
showed up, and confronted Bloodtype. He defeated Bloodtype without much effort. One of the Piper's robotic pipes exploded, severely wounding Bloodtype. He died in St. Bartolomew's Hospital.
Later, his ex-wife Death-Doll tried to avenge his death by killing Aztek, but was unsuccessful.
