Air Zonk is a re-imagination of the Bonk video game series as a scrolling shooter set in the future.^[1] Artistically, the game is lighthearted, featuring humorous designs of the environment and the characters.^[2] During each of the five levels,^[1] the gameplay centers around the effective use of shooting and bombing to complete a stage. At the start, the player may pick a companion character to team up with, such as an anthropomorphic gumball machine or mummy with a drill attached to its head,^[2] in order to boost the Bonk's powers.^[3] The players can choose to limit the use of the designated companion characters for each level, or opt out of using companion characters altogether. Each companion character, or friend, can only be used once. Air Zonk takes on the distinct visual style that is sometimes called a "cute 'em up". There are three difficulty settings: sweet, spicy, and bitter.

Zonk can charge his shots, which allows him to fire a more powerful attack. Charging longer causes Zonk to drop a bomb, which damages all enemies on the screen. Zonk can also acquire seven types of power-ups, each of which can also be charged for a unique special attack. As usual for scrolling shooters, whenever Zonk acquires a new power-up, he loses the current one. If Zonk is hit while he has a power-up, he loses the power-up but does not die, except in the case of the Mini-Zonk power-up. The Mini-Zonk power-up also differs from the other power-ups in that it cannot be charged, and can be found in both florets and random enemy drops (other power-ups can only be found in florets).

Zonk starts each stage alone and with no power-ups. He must collect eight smiley faces, the eighth of which will appear in giant form with sunglasses, in order to get his friend to join him. The friend initially acts as a Gradius-style support which follows Zonk around shooting projectiles. If the player collects another eight smiley faces, Zonk and the friend will merge into a hybrid form,^[3] granting a new attack and 20 seconds of invulnerability. This new attack cannot be charged, and Zonk cannot drop bombs while in hybrid form. Once invincibility expires, if Zonk is hit he will revert to normal form and his friend will leave, though he retains whatever power-up he had before changing to hybrid form.

Air Zonk was awarded Best TurboGrafx Game of 1992 by Electronic Gaming Monthly.^[8] The game retrospectively has gained a cult following. Air Zonk is often considered by many game critics to be one of the best games ever released for the TurboGrafx-16.

Air Zonk received a sequel in 1993 named Super Air Zonk: Rockabilly-Paradise (also known as CD Denjin Rockabilly), which was released in the SuperCD format and requires the Super System Card to play on first-generation TurboGrafx-CD consoles. As its name would imply, the game has a CD audio soundtrack consisting of rockabilly music. The game contains all-new levels, assistants, and enemies.

Air Zonk was released in 2007 on the Wii's Virtual Console in May in Japan, July in America, and on July 13 in Europe.^[9][10][11] It was also released on the Wii U's Virtual Console in Japan on June 19, 2014, in America on July 27, 2017, and in Europe on August 3.^[12][13][11]
