Along the way he'll learn to work together with Team RWBY and JNPR, while saving Remnant from falling to darkness by the mysterious Salem with the help of his new team, Team 10 with his friends Rex Salazar from his previous adventure and Zak Saturday the Cryptid Hero. However, he would learn about his special Destiny that would tie his fate to the entire Multiverse while starting his own Family... A Big Family with a lot of girls...
