Armor Claw was Rocigon's childhood imaginary friend. He taught him how to analyze the enemy and pursue his passions. After winning a tournament, Rocigon was given a trophy, with amber decorations and, as he looked at it, he thought "Thanks, old friend". Within seconds, the amber released a substance which transformed into a living Armor Claw!
Design and name are inspired by notable Monster Legends YouTuber Armor Gaming who ends his videos by reminding his viewers to "dream big and pursue your passions."
