Mikey has an overly outgoing personality. He is always happy, and often tries to see the good in his enemies, much to Shoutmon's chagrin. His motto is "I can't turn my back on anyone." Mikey cares for pretty much everyone, and wishes for an all good world where no one is evil. He has a tendency to never refuse a favor asked to him and often overexerts himself to the point of collapse and even endangering himself, which often gets him yelled at by Angie.
