After Robert Haydn loses a battle to Ueki, he begins to doubt himself and the path of destruction he has chosen to follow. In response, his father (who is, in fact, an Infernal in disguise) brings in Hanon (another Infernal) to replace him. Robert battles Hanon, but is easily defeated. Hanon then grabs Robert and swallows him whole, absorbing him and taking on his identity so he may take his place in the tournament.
