The Ankylosaurus Yummy (アンキロサウルスヤミー Ankirosaurusu Yamī) is created by Doctor Maki from shards of ice that Ankh (Lost) broke apart after still feeling incomplete because he is missing one more Medal. The Ankylosaurus Yummy's body is covered in sharp thorns and his right hand ends in a powerful mace-like ball. He can also fire shards of ice out of his body and spray freezing mist. While fighting Kamen Rider Birth, the Ankylosaurus Yummy is destroyed when hit by the Breast Cannon's Cell Burst at point blank range.
