Air Zonk

Air Zonk (PC Denjin in Japan) is a spin-off of Bonk, set in the distant future with Zonk, Bonk's sunglasses-wearing cyborg descendant.

The series is a Cute'Em Up with a transformation gimmick. Zonk can merge with one of his teammates (or a small robot, depending on what game you're playing) to use unique weapons

The sequel was titled Super Air Zonk: Rockabilly Paradise (CD Denjin: Rockabilly Paradise in Japan).

The Air Zonk series contains examples of:

 * American Kirby Is Hardcore: The Japanese version had PC-Denjin flying past the PC-Genjin logo before landing and revealing his squad and logo. The US version has Zonk standing on a building (resembling Bonk moreso then usual), using his sunglasses to transform into his cyborg form and fly off.
 * Big Bad: King Drool/Sandrovich, the decendant of the King Drool from the Bonk series.
 * Bowdlerise - When Zonk fused with Moo Moo in the original Japanese version, he gained Gag Boobs that shot milk at the enemies. This was changed into Zonk shooting it from milk bottle arms in all other releases.
 * Most of the Toilet Humor was removed from the US version of Air Zonk, in addition to a Drag Queen moment from King Drool.
 * Cool Shades - Possibly the Trope Codifier. Zonk, his team, the Floras, and even his missiles he can crap out all wear sunglasses.
 * Dastardly Whiplash - The Zonk version of King Drool.
 * Darker and Edgier - Compared to the previous Bonk games, Zonk was an attempt to re-invert the franchise both design and gameplay-wise.
 * The Dragon - Two deformed clones of Zonk, one with antennas and a butt-shaped head and the other with a Mohawk-like growth on his head.
 * Dub Name Change - The Big Bad of the Zonk series was called King Tamagoden (King Eggbowl) in Japan. While the first game used the English name of his Bonk counterpart (King Drool), Super Air Zonk calls him Sandrovich.
 * Fusion Dance - Zonk can fuse with any of his teammates to power up, resulting in bizarre forms.
 * Game Over Man - King Drool and his Zonk clones appear at the game over screen of the first game, performing a victory dance over your loss.
 * Getting Crap Past the Radar - Quite literally in the first game. Zonk can charge up his shots to do more damage. Charging up for about five seconds however, makes Zonk poop out a missile (with sunglasses) that does a lot of damage.
 * It actually is crap (again, with sunglasses) in the Japanese version.
 * King Drool's logo in Super Air Zonk is a pink pile of crap. It appears very often throughout the game.
 * Nostalgia Level - Subverted. Halfway into the final level, the player enters what appears to be a recreation of the first level of Bonk's Adventure, complete with enemies from the original game. After a few minutes, the background falls apart to reveal machinery and all the enemies are shown to be robotic.
 * Also, the music that plays when Zonk fuses with one of his partners is a upbeat remix of the Invincibility theme from Bonk's Adventure and Bonk's Revenge.
 * Sequel Difficulty Drop: Super Air Zonk. You don't lose your fusion powers if you get hit, and your lifes are more like health extensions, since Zonk doesn't die until he loses all of them. The option to choose levels helps too.
 * Similar Squad - Zonk and some of his teammates are future counterparts to Bonk and his friends from the first game.
 * To be specific, Spike Lee and Astra are future versions of Kongo Zilla and Princess Za, respectively.
 * Most of the enemies count too. The Hatchets are bucket-helmeted lizards in the future, and the Florets wear sunglasses and float.
