Elbow is likely a skilled warrior as they are capable of training others.[1]
History
Over 56 years before the present day, Elbow was scheduled to do warrior's training with Hajrudin in the Western Village.[1]
Trivia
Hajrudin was previously seen training with the giant Raideen. It is unknown if he switched mentors or if Raideen and Elbow trained Hajrudin simultaneously.
Like many other characters from Elbaph, his name may reference professional wrestling, specifically the Collar-and-elbow position, and the elbow strikes common in the sport in general.
