GaiaLeon is a sentient A.I. lion themed Rescue Vehicle from Tomica Hero: Rescue Fire. It was developed by Bunji Saeki for Riku Taiga to use, but the mecha will work with anyone it acknowledges as having a burning Rescue Soul. Like the animal it is based off of, GaiaLeon is very prideful and acts on his own, thus it did not work with anyone but Riku at first, but Ritsuka and later the others gained his trust. It also possesses an alternate Vehicle Mode, a super construction excavator machine with twin drills, a shovel, and a bulldozer plow. In both modes. it is powered by a VVEL engine.
