A series of bioweapons that Millie created by combining Tyrannosauruses with a variety of monsters, consisting of a Chickennosaurus, Dullahannosaurus, Longlocksaurus, Devil Tyranno, Tentacle Tyranno, and Franken Tyranno. They're as tough as you would expect of bioweapons, so despite it being assumed that they had died when Millie detonated the bombs she planted in them, they managed to cling to life thanks to Tyra's desperate efforts to save them. They're now living happily as a part of Tyra's family.
