Army Dillo
Army Dillo is a Gargantuan Army that is a boss in the game Donkey Kong 64. He is appointed by King K. Rool to be the Army guardian of not one but two keys to K. Lumsy's cage. In his first fight with Donkey Kong, Dillo is equipped with two large retractable side-mounted fireball cannons, and a metal shell.
After Army Dillo is defeated by Donkey Kong in Jungle Japes, he is cowering in fear while being watched by King K. Rool. Dillo says to K. Rool that Donkey Kong was too quick for him, and that he will "get him next time", most likely referring to their second encounter in Crystal Caves. K. Rool however, is angry the Army Dillo's failure, and punishes him for, in the form glaring at him a way that somehow knocks him on his back
Before he faces Donkey Kong for a second time, Dillo is retooled in a Kremling base in Crystal Caves. His weaponry is upgraded with side-mounted rocket boosters, which gives Dillo the ability to perform a shock-wave ground slam. He is also upgraded with a gigantic top-mounted cannon, capable of launching rapid streams of fireballs and rockets. However, even with these new upgrades, Dillo is defeated by Donkey Kong once again, and the explosion of his top-mounted cannon scrapped his metal shell completely, and he curled up and gave DK the sixth K. Lumsy Key. It is not elaborated what happened to Army Dillo after the rematch.
