Come Forth My Persona

Is an upcoming crossover fighting game featuring characters from the Japanese animation studio Tatsunoko Production and video game company Capcom.
Each player will have a team of two, and players can switch their characters at any time, and even perform two special moves at the same time (which however uses up two special bars). However, large characters, such as Tatsunoko's Gold Lightan and Capcom's PTX-40A will fight on their own without a partner.
