Born in GrooveClan, he's constantly looking for acceptance and tries to prove his worth whenever he can, this lead to a nasty personality that tried to put other warriors down. 

After the cold-hearted leader died, he softened up and became nicer. Although this was also due to Beetlewing's influence. He dragged Beetlewing into his plan to overtake the current leader but later on gives it up and decides to run away with his first ever friend to a calmer life away from all of the clans.
