Coldblood (Eric Savin) is a fictional character in the Marvel Universe who first appeared in Marvel Comics Presents vol. 1 #26 (August 1989).

While still a Lieutenant Colonel in the United States Army at Camp Killian, Eric Savin was put in charge of Project: Ultra-Tech. There he met the love of his life, Lieutenant Gina Dyson. While on patrol, Savin stepped onto a freshly planted mine which blew him into pieces. He was dead for 2.3 minutes. Gina immediately performed cybernetic surgery on him. The surgery was successful — Savin was alive, but resurrected as a cyborg by Mako's Project: Ultra-Tech. Dyson, his former lover, aided him in battling Mako and his robots, and apparently slew Mako in combat. The "7" in Coldblood's original name was stated to be a mere wordplay on Coldblood's real name "Eric Savin", as his surname is pronounced in the same way.

Coldblood became an urban soldier cyborg, operating as a freelance mercenary. He evaded capture by Mechadoom. Coldblood hunted down and fought the third Deathlok in Paris. He then joined forces with Deathlok and Siege in defeating Harlan Ryker and his cyber-warriors.

Coldblood gave in to his cyborg-form at one point but with the help of Gina was brought back to the human side in him.

Coldblood has not been a contender in any CBUB matches.
