The determined leader of the Smiling Critters and the Watchdog of the Sanctuary. If he ever sees anyone without a smile, he does whatever he can to give them one. Despite having a rough childhood, and dealing with Dane's (childhood bully) antics, Apollo’s fiery perseverance remains, and is expressed when confronted. Underneath that fiery exterior, Apollo is known to be gentle and give support when needed in the worst of times; not just to his friends, but to the Cosmiteers and the children that reside within the walls of the Sanctuary.
