He once again acts as a referee in Mario & Sonic at the Olympic Winter Games and Mario & Sonic at the London 2012 Olympic Games.

Personality
Espio, unlike the majority of his allies, is very serious, calm, wise and disciplined. He is a master of ninjutsu; his battle poses and shuriken stars support that portrayal. Described as the “guardian of honor” of the Chaotix, he is not afraid of danger, and often looks for it to face it in order to use his ninja skills. He is always training and believes in self-discipline, but however is opinionated and sometimes arrogant.
