I'm pretty sure this character is hispanic, so if you have hispanic ancestry I strongly encourage you to audition! However, anyone can audition. 

Miguel is a famous gold medalist who takes a break from his career. This decision shocks everyone. It is later revealed he does this because he is now afraid of swimming. He is kind and understanding, but always endures pain and hardship on his own. He doesn't show his true feelings or complain to others. Miguel is outgoing and is the type of person anyone can rely on.

Voice: Up to interpretation. Maybe friendly and outgoing could work
