Skylanders Unleashed: Actionoplis

Here we are finally with the Japan level

Shadow-chan: Once a normal girl, Shadow-chan used to be know as Buranku-Chan(Blank-Chan). One day while walk back home from school, she found a strange building. This building led down to small portal which brought her to Skylands. At the moment, Skylands was being corrupted by a dark force which infected Buranku and made her into what she is now. with a small case of mental unstableness, Buranku-chan and her new found powers to summon the dark force of the underworld became Shadow-chan. Now she fights along with the skylanders but in a more demented style. 

Mechzilla: Once an ancient weapon used by the old sociality before Actionoplis, Mechzilla laid dormant for eons before being woken up by the evil forces of Kaos. This led him to take action and he fought against the forces of Kaos. Now he is a hero to the city if Actionoplis and to the skylanders. He join the skylanders mostly to keep an eye on them since he doesn't trust people very easily. 

Frightmare: Frightmare once was a spirit of evil and darkness, actually working with Kaos himself. One day, in fighting Ambush in a small forest, Ambush convinced Frightmare that there is more to the world then evil and money. This made Frightmare think about the things he has done and cause him to leave his evil past to join the skylanders in there quest for peace and fits right in with his strange magic and dark power over sleep. He's still a prick thought and loves to pull pranks on his fellow teammates.  

I was in inspired by one of CheesySquidSandwich's character Sinistina in the design for shadow-chan so that's why they look sort of similar
