A mole from the Animal Crossing series who, just like in the games, gives long and boring lectures, which tend to block either the top half of the screen, or the player damage levels, and sometimes the dialogues interact with certain events in the battle. Like Nintendog, he isn't a positive effect for anyone.
A pilot of the USAF from Street Fighter. When summoned, he crouches down waiting to attack. When facing opponents from a distance, he fires his Sonic Boom. If an opponent gets too close, Guile swats them with his Flash Kick. He can also block projectiles. After some time, he brushes his hair for a moment and leaves.
The demonic bartender who serves as a merchant in the Bayonetta series. He is in reality the strongest regular angel in existence and was casted down to Inferno in the distant past. When summoned, he will start attacking the opponents with his own version of the wicked weaves before leaving an usable item upon departure.
A reploid from the Mega Man series. When summoned, he can do a three-hit slash combo with his saber. He can also fire a large green Genmu Zeru projectile. Zero can also do a fiery Ryueijin and a spinning Kuenzan in midair.
