Spotter is a Rabbit who competed against Jumpy Ghostface to be the Rabbit King's successor. Rabbit King selected Jumpy Ghostface to be his successor instead of Spotter the Rabbit causing Spotter to leave. Upon training with some bad guys and mastering the full human language, Spotter befriended the Mantis army and they invade Rabbit Castle where he captures all the Rabbits leaving one to let Jumpy Ghostface know that he is back. While First Squad and the Beetles fought the Mantis Army, Jumpy Ghostface dueled with Spotter the Rabbit. After Spotter the Rabbit was repelled and the Mantis Army also takes their leave, the other Rabbits were rescued.
