In Operation 005-C, the boss battle is designed to play similarly to the Punch-Out series. The Gah-Goojin that the team pilots has two attacks, one obtained by collecting stars, the other by landing hits. These are references to the Star Punch in the NES Punch-Out!!, and the Knock-Out Punch in the SNES Super Punch-Out!!.

The character Wonder Cheerleader is modeled after Silvia from Viewtiful Joe. Her gun, Desperado, is also the name of a technique that Silvia learns in Viewtiful Joe 2.

The secret character Poseman is a reference to Viewtiful Joe. Not only does he resemble Joe physically, he does some of his poses, has a move called "Heroic Forever" which is similar to Joe's "Viewtiful Forever", and his title is "Go for it!", which refers to the introduction of each scored segment in the Viewtiful Joe games.

The enemy known as 'Gatcha' is modeled after Japanese capsule machines known as Gachapon. Like a Gachapon machine, the enemy features a knob that, when turned, causes it to dispense round capsules containing an object.

Originally, the game was meant to have an all-star cast of Nintendo characters, plus characters from other games. Hideki Kamiya came up with the gameplay as a way to satisfy fans of all the different characters, as different gamers would prefer certain characters over others. As such, he decided to make all the characters appear at once, so that the fans could pick and chose which character to use. After the game was shelved for some time, it was decided to drop the all-star Nintendo cast to create an all new superhero cast.

Wonder White has the kanji 百 (hyaku) on his head, the Japanese word for hundred. Spoiler:Later in the game, it gets broken partially, turning it into 白 (shiro), the Japanese word for white.

In the news report shown during Bayonetta 2's opening cutscene, the mission complete music from Wonderful 101 can be heard in the background.

Wonder-Magician's civilian name, Harry Silverfield, is loosely named after the illusionists Harry Houdini and David Copperfield.

In the first meeting with Wonder Pink, Wonder Blue will comment "Hey, can we save the meet-and-greet for later!? We got a pain in the butt hedgehog to get rid off!", referencing the Gedie Dough-Goo they are under attack from and unable to defeat. The Gedie Dough-Goo itself is covered in blue spikes and has a spinning ball attack, making a strong reference to Sonic The Hedgehog.

This is also ironic, as Wonder Blue's english voice actor is Roger Craig Smith, who also voices Sonic the Hedgehog in the modern-gen Sonic games (Starting with Sonic Free Riders and Sonic Colors in November 2010).

The supporting robot character P-Star gets his name from the ##Platinum Games## logo, which itself is the letter "P" next to a "star."

Spoiler:Near the end of the game, when the Wonderful 100 unite into Ultra Platinum in the fight against Wonder-Jergingha, the ##Platinum Games## symbol can be seen right before it becomes Platinum Robo.

The minor character Wonder-Gamer has a Famicom controller on top of his helmet. He is also assigned to Kyoto, the birthplace of ##Nintendo##.

Wonder Yellow's civilian name (Ivan Istochnikov) comes from a Lost/Phantom Cosmonaut, which is a Soviet Cosmonaut that has entered space but has had their existence suppressed/wiped from history by their government. Ivan Istochnikov's story turned out to be a hoax, however.

Wonder-Pink is originally from Romania and assigned in Transylvania, and uses a whip composed of "Belmont alloy", all of which are references to the whip-using Belmont family from the Castlevania series.

The minor character Wonder-Beetle has the title of "Not the Car, Not the Band", referencing both the Volkswagen Beetle car and the band The Beatles.

During Wonder Pink's introduction scene, one of the poses she makes is the same pose made by the Title Character on the Japanese Cover of Bayonetta, another game developed by ##Platinum Games##.

Wonder-White's civilian surname (Byakkoin) comes from the Japanese term byakko, or "white tiger" from the Chinese prophecy.
His first name (Momoe) means "hundred blessings" in Japanese. Oddly, "Momoe" is generally a female name.

The minor-character Wonder Rex is assigned to Great Falls, Montana in the USA. Montana houses the Museum of the Rockies, which holds the most dinosaur fossils in the United States, alongside other palaeontological finds. A great number of finds have been found in the state of Montana, most notably the largest Tyrannosaurus Rex skull discovered to date.

While her mother being a pro-wrestler explains Wonder Rex's Fist-based abilities and even costume, her father is titled as an archaeologist, which is actually a field of study specifically about human activity in the past. Palaeontology would be the correct field of study concerning dinosaur fossils.

Jeanne, Bayonetta, and Rodin from the Bayonetta series make cameo appearances as unlockable characters, each having their signature weapons from the games. Unlocking them requires at least a Platinum-ranking on each stage.

Wonder-Fixit's civilian name is Felix Fermintxo, which is possibly a reference to Fixit Felix Jr. from the video-game centered movie Wreck-it Ralph.
