Marino is a character first appearing in Bust-A-Move 4. He is the son of Queen Naleto and prince of the planet Wavy.
The North American Dreamcast booklet describes him as this:
"He's the son of Queen Naleto of the planet Wavy. He's a straight forward character, but a bit of a simpleton. He embarks on a journey to find the "morning", because the Kingdom of the Sea was roughed up by the incident."
