A purple cat yo-kai with a light purple face. It's nose is magenta, while the inner ear is golden-yellow. Over it's eyes are a pair of sharp sunglasses, revealing the scar over the left one. He has a dark-purple pompadour. He wears a dark-blue outfit with the kanji for 'Rebel' on the back and a pair of black shoes. The tail flames are lime-green.
Baddinyan, like Roughraff, acts like a very tame delinquent. He speaks rudely, eats sweets before dinner, and litters. Due to still being Jibanyan he adds 'nyan' to his sentences. In Yo-Kai Watch 2 Bony Spirits and Fleshy Souls, he is only obtainable by fusing Jibanyan and Roughraff when you and your team see Coughkoff and Roughraff fighting over who is the spikiest. If you say Roughraff is the winner, you will get Baddinyan.
Like Roughraff, his Inspirit makes others turn to delinquency.
It looks like Baddinyan doesn't really care about Nate and Whisper. Nate is, however, annoyed that Baddinyan is doing some nonsense things. In EP067, it is shown that in the alternate universe where Katie has the watch, Baddinyan replaces Jibanyan.
Go to the apartments in Shopper's Row, where Roughraff and Coughkoff are arguing over who is more spiky. To obtain Baddinyan, speak to Roughraff and say he's the spikier one. He will then fuse with Jibanyan to form into Baddinyan, the fusion breaking apart after Baddinyan gives the player their medal.
Fuse Jibanyan with Roughraff, this only consumes Roughraff. Baddinyan can also be freed from the Crank-a-kai.
In EP003 of the anime, Jibanyan is inspirited by Roughraff and transforms into Baddinyan, promptly developing a rebellious streak... which turns out to be amusingly tame, consisting of petty misdeeds like eating two chocobars at a time and scattering the wrappings around.
Jibanyan is transformed into Baddinyan in EP035 in the role of a pirate captain for the pirate scene of Directator's latest film "Yo-Titanic-ai" where he was assisted by B3-NK1, Dazzabel, and Roughraff.
He was also briefly seen in Mochismo's Recap. He was silent for most of the time, but the only quote he uttered was "Yeah, He's Tough!" At the end.
When being released from Crank-a-kai (Yo-kai Watch: Wibble Wobble):"Heh. Dude, you got no idea how lucky you are!"
Baddinyan is one of the few forms Jibanyan has who is simply inspirited by another yo-kai, rather than being fused together.
Baddinyan is also the antagonist of the Japanese television spots for Rohto Eye Drops, teaching viewers what NOT to do with your eyes.
Baddinyan's "random" nicknames in Yo-kai Watch 2 are: Badboy, Junior, Sonny, and Pompable.
"Baddinyan" is a portmanteau of baddie and nyan.
"Warunyan" is similar, but instead combines with warui (悪い, "bad, evil, rascal").
Baddinyan's Japanese Soultimate name contains an old slang typical of the delinquent youth that was often used in graffiti, namely writing yoroshiku (よろしく, "nice to meet you") with the individual kanji for "night", "dew", "death" and "suffering" (夜露死苦) formed into one homophonic string.
The Japanese name of the Pompadour skill is the local name for the ducktail hairstyle, which it got the name directly from London's Regent Street.
