Exzo looks unlike any other Shalos, with a dinosaur-like head and four arms. He has a crest in his head and has shadowicle floating around his head. He dresses basically the same as Attackey
. Gray shirt with the green crowned Sea Shadow
with antlers, a hole for his tail, and boots. He also has a fuchsia cape with the same green Sea Shadow.
Once the prideful king of the Shalos, Exzo never wanted his race to be destroyed. When Destonator invaded their planet, Exzo witnessed all the brave Shalos dying to defend their planet. To put an end to the Shalos' deaths, he thought smartly and hatched a plan. He surrendered and agreed to help Destonator in taking over the Universes. However, Exzo never wanted to conquer anything. He was waiting for the right moment to defeat Destonator, but the more time he waited, the more he saw he didn't stand a chance against Destonator.
