Let's Fight to the End
The Pow Card company decides to hold a tournament with T.K.O. joining for his and Shadowy Venomous' own nefarious scheme. Rad and Enid join in to rescue their friend and stop the villains once and for all. Shadowy Venomous manages to secure the glorb tree for himself and plans to drain the powers of all the heroes in the world. K.O. fights his way out of T.K.O.'s mind and discovers a hidden memory that could very well save his and everyone else's lives.
