Emerl is a robot and one of Sonic's friends who came to his rescue during his fight with the Troll King. He was able to copy the Trolls' moves because in the game he was from, Sonic Battle, the characters fought each other so that Emerl could learn their fighting styles and become stronger. He managed to fight Troll King for a while until the Trolls all ganged up on him and Troll King sliced him in half.
