Dub was a nice beige monster at first, as Pyrare informed the other caretakers and heroes in Episode 5. However, as Dub got along with Barracuda, Pyrare's son, Dub made the virus. Barracuda died for an unknown reason and this transformed Dub into what he is today. Dub is a vile monster who wants to continue and finish Barracuda's plan. He plans to corrupt as many shapes as possible and make all of Paradise bow to him..however..maybe he can improve.
