Baby Wario

Baby Wario is the baby version of Wario, appearing in Yoshi's Island DS, along with Baby Mario, Baby Peach, Baby Bowser, and Baby Donkey Kong. Not much is known about this infant, but it appears that Wario was greedy even as a child. Baby Wario's special move has been officially stated to be "magnetism", which allows him to grab Adult Wario's favorite things, Coins. His magnet may also raise metallic platforms and move large, metal boxes.

When Baby Wario was originally kidnapped, the Toadies found his tantrums to be very annoying, so they left him alone in World 3-5. Some time after that, Yoshi, who had been washed away by a large wave and seperated from the Stork and other babies, finds him. Baby Wario assisted Yoshi throughout the rest of World 3, but he got away from him after World 3-8, joining up with a group Bandits in hope of even more riches. Yoshi and the rest of the babies meet up with Baby Wario one last time in Bowser's Castle, having an argument with Baby Bowser. Baby Wario helps the Yoshis by defeating Bowser on the back of Purple Yoshi. After the castle is destroyed and the team find the babies, Baby Wario lands on a very large treasure chest filled with Baby Bowser's treasure. However, Baby Bowser falls and lands in the treasure as well, initiating an argument over it.

At the end of the game, it is revealed that Baby Wario is one of the seven Star Children.
