The aircraft Sky Ace (スカイエース Sukai Ēsu?, 1-23, 32, 34-J.A.K.Q. vs. Gorenger), which is usually piloted by Spade Ace or Dia Jack, but had three other pilots: Clover King, Joker, and Keiko Hayashi (Agent 7).

Gaoranger vs. Super Sentai
Years later, Sky Ace appeared as part of an army of robots, animals, jets, machines and vehicles belonging to the first 25 red heroes. As anticipated by Soukichi Banba (Big One), they were led by Akira Shinmei (AoRenger) and Chief Counsellor Naoyuki Miura to help fight Lost Highness Rakushaasa.
When GokaiOh and Gosei Great faced the Black Cross Colossus, the mecha of the first 33 Super Sentai, including Sky Ace which possibly manifested from a toy version like DaiDenzin and the Variblune, appeared to back them up. Variblune and Sky Ace proceeded to assault the Black Cross Colossus, followed by Battle Fever Robo using its Chinese Bamboo Slice on him. When the Black Cross Colossus summoned several giant villains to oppose them, Sky Ace along with Variblune attacked Brajira of the Messiah, leaving an opening for him to be defeated by GokaiOh and Gosei Great. After all the giant villains were destroyed, all 35 mecha weakened Black Cross Colossus with a combined attack before GokaiOh combined with the Variblune to become Goren GokaiOh which destroyed the Black Cross Colossus with the Gokai Hurricane: Cassiopeia finisher. With the battle won, the 33 past Super Sentai mecha vanished.
