Design and Conception[]

Here is what the designers have to say:

Character and Personality[]

Baby-Lon is described as a sleepy yet adventurous and happy baby. This can be seen in his story when he travel's through Disco's town all by himself (despite him being a baby) as he tries to remember where he is trying to go. As well, in his story, Baby-Lon travels to outer space proving his adventurous side.


Baby-Lon appears to have short fluffy orange hair and black eyes with white iris. He wears a cyan beanie to show off his hair and the tip of his beanie has a star design and teal and red magical earmuffs with star designs which was given by his Italian unnamed father who is an adventurer and letting his mother Maho to wore the earmuffs. His magical earmuffs changes throughout his appearances starting from DDR SuperNOVA onward.
