The ZERO-ONE (Japanese: ゼロワン号 No. ZERO-ONE) is an all-terrain safari vehicle designed by Professor Oak. It can acclimate itself to several different environments by using wheels, inflatable pontoons, and jet thrusters for travel over the ground, in the water, and through the air. The ZERO-ONE has no steering mechanism. Instead, it will follow a set path preprogrammed by Professor Oak. It has an automatic braking system which activates if a Template:OBP should get in its path.

Todd Snap rides in it in the Nintendo 64 game, Pokémon Snap. Using the ZERO-ONE, Todd is able to safely traverse the many locations of Pokémon Island. When he shows Professor Oak one of the Pokémon signs, Professor Oak upgrades it with the Dash Engine, which allows it to go faster.
