Baddinyan appeared in 2013 video game called Yo-Kai Watch. Baddinyan (Japanese: ワルニャン Warunyan) is a Rank B Fire-attribute Yo-kai of the Charming tribe.
As of Yo-kai Watch 4, he is a One-chanside Yo-kai of the Onnen tribe.
In Yo-kai Watch Baddinyan evolves from Jibanyan when fused with Roughraff. As of Yo-kai Watch 2, Baddinyan is a stand-alone Yo-kai and can no longer be obtained by fusing Jibanyan.
In Yo-kai Watch Blasters, he is one of the Yo-kai required to unlock Shogunyan.
A purple cat yo-kai with a light purple face. Its nose is magenta, while the inner ear is golden-yellow. Over its 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.
