The Monoceraptor was first mentioned in the Battledome's scrolling marquee, the day before the invasion itself began. The message read "The Monoceraptor will crush your puny Tyrannia!". Speculation as to who or what the Monoceraptor was was fuelled with a proclamation of his imminent arrival on 9th May. The Monoceraptor held true to his word, and stormed into Tyrannia the next day, after all his waves had been defeated.
