Kalinka Cossack

Kalinka Cossack is the nine year old daughter of Dr. Cossack. Dr. Wily kidnapped her to force Dr. Cossack to fight Mega Man in Mega Man 4, but Mega Man and Dr. Cossack stopped their fight when Proto Man saved her and reunited her with her father.

She and her father first appear as player-controllable characters in Wily and Right's RockBoard: That's Paradise. In this game, she hopes to build a lot of castles in the world and realize her dream of becoming a princess.
