Apollo's two dominant traits are his Immense intelligence/Cunning Mind and his utter fearlessness. Like Luffy, Apollo can (Sometimes) easily be amazed by the simplest things, such as hermit crabs, and can be confused by concepts such as that by digging a hole right next to another he may be unintentionally filling the other hole. He is also shown to have a HUGE sweet tooth and will always have something sweet on him at all time wither its a lollipop or ice-cream, this can be considered a weakness because if he doesn't get any thing sweet he will grow weak and his body will start to drain any sugar in it.
