The Transmutant.J.B. spars with Ryan in an effort to relax before taking a test to qualify for a scholarship. When sparring fails to work, J.B. tries to relax in the park. Skugs attack him and draw him into the BattleGrid where they administer the Metamorphosis Pulse -- a weapon designed to gradually change humans into virtual mutants. Professor Hart informs Kaitlin and Ryan that J.B. is under Grimlord's influence. As one of Grimlord's mutants, J.B. forgets who he really is and fights other mutants for position. Grimlord sends the mutant J.B. to fight Ryan, as Kaitlin works with the Professor to recover their fallen Trooper. Ryan manages to save J.B.'s life and, as the Transmutant, J.B. fights by Ryan's side and defeats the other mutants. At the lab, J.B. regains his human form just in time to take the test -- an exam about which he's no longer worried. His experience in the Virtual World has allowed him to put the scholarship in proper perspective.
