Two versions of the Pteranodon Yummy appear as antagonists in the Kamen Rider × Kamen Rider OOO & W Featuring Skull: Movie War Core films, created by Giru. After the female was driven away by Nobunaga as Kamen Rider Birth, a male Pteranodon Yummy appeared in Futo to collect the memory of all past Kamen Riders battles with Memory Memory, finding an ideal one by using the Gaia Memory on Akiko to reveal how her father became Kamen Rider Skull. After Kamen Rider Core is created, the male Pteranodon is later destroyed by Kamen Riders Accel and Birth.
Another pair of Pteranodon Yummy appear in the television series in episode 32, after the Purple Core Medals enter Eiji's body. They proceed on using their mist to dissolve people into nothingness until Kamen Riders OOO and Birth show up. The two Yummy hold the Kamen Riders at bay until the purple Core Medals react and transform Kamen Rider OOO into Putotyra Combo. After the female destroyed with Kamen Rider OOO Putotyra Combo's Scanning Charge, the male was destroyed with Strain Doom Putotyranno Hissatsu. After having the other Core Medals enter his body, Maki produces a Pteranodon Yummy using the candle he had used to burn his sister to death. This Pteranodon Yummy is soon used to by Maki to test Eiji's worth as a more ideal holder of the purple Core Medals, easily destroyed by Kamen Rider OOO Putotyra Combo.
Pteranodon Yummy revived once again and part of Space Shocker.
