|[List of appearances]|
Neuro was one of the Elemental Masters invited to Master Chen's Tournament of Elements on Chen's island. When the first challenge began, where the Elemental Masters had to acquire a Jade Blade to reach the next round, Neuro briefly fought Lloyd for a blade, but Lloyd quickly fended him off. However, Neuro was successful in finding another blade and move onto the next stage of the tournament.
In the second round, competitors were paired up against an opponent where they had to fight for a single Jade Blade. Neuro went up against Bolobo and managed to eventually overcome him by using his mind powers, unleashing a psychic attack on Bolobo even after the Master of Nature tied him down with vines.
Later that night, when Chen changed the brackets so that Jay was scheduled to fight Cole, the ninja came to Neuro, asking for his help. The ninja asked him to read Chen's mind so that they could find out where on the island Zane was being held so that they could go to free Zane before Jay and Cole had to fight. At first, Neuro declined as the ninja were his competitors, then Lloyd asked Neuro to read his mind. After accessing Lloyd's memories and seeing how Chen had imprisoned Karlof and taken his powers, Neuro agreed to help.
He attempted to get close enough to Chen, but he was found by Clouse and was forced to leave. However, Neuro was able to quickly read Clouse's mind and learned that Chen was absorbing the powers so that he could perform a spell, a spell which was located on page 149 on Clouse's spellbook. Neuro then passed on what he had learned to Lloyd shortly before the match between Cole and Jay.
