Erik Horse is a Mobian horse and a Freedom Fighter. He was contacted by Sally Acorn along with other Freedom Fighter groups following the demise of Dr. Ivo Robotnik to be warned about the creation of various zones due to the firing of the Ultimate Annihilator. He later went parachuting with Sally, Rotor, Hamlin, Hershey and Lupe, though he ended up landing in a tree. When asked if he was alright, he replied "Only my pride is shot!". Sally then cut his parachute and freed him, after which their group had dinner with a local family before returning home. (StH: #52, #59)
