Lion (ライオンくん, Raion-kun) is a Ham-Ham who appears in some of the Japanese episodes. He is friends with Otome and Bear. They all love art and are constantly saying "Go, go, art, go!" He is not to be confused with Leo, who is also based off of a lion.
He has a fiery personality, similarly to Otome, and is known to interject with "bari bari~!" within his sentences. This is a Japanese sound effect which means "raring and ready to go" or "full of energy". However, his fire can be quelled if Otome is angry with him.
