Serpentor over Cobra Commander and Baroness
Serpentor is the name of a giant cobra who belongs to Cobra Commander in G.I. Joe: Renegades. Created by Doctor Mindbender as a gift to Cobra Commander, Serpentor possesses enough intelligence to follow basic commands and even swallow any human that angers Cobra Commander as well as spit them back out on cue, if Cobra Commander decides to let that person live.
