Commander Ape Trully is a main character of Hero 108. He is the well-meaning leader of the making force known as Big Green. Commander Ape Trully formed Big Green in hopes of restoring friendship between animals and humans. This reunion, however, was not easily achieved and certainly not through Ape Trully's rather naive peace negotiations which begin with an offer of gold and usually end with him being captured by the enemy and summoning First Squad to his rescue. Ape Trully is actually a real Monkey King, but hides his true identity because he mistakenly believes that the heroes of Big Green will never follow a monkey. So, he wears a disguise that looks more like a monkey's idea of a human than a human itself. Ape Trully is well schooled and knows a great deal of archaic knowledge of the land. He learned the Human Language from the Parrot King in the times before the war. He is also known for uttering sweet, inexplicable exclamations such as "Sweet Banana Pudding!" and "What in the name of monkey crumbs?" He flies a personal helicopter, closely followed by the Big Green Air Force, First Squad and/or Army for his own protection.
Umbrella Hat: Ape Trully wears a special umbrella hat both in and out of disguise, which has the ability to turn into a satellite to summon First Squad or be used like a parachute.
