Lou

 Lou '''is Cole's father and a "Royal Blacksmith" who loves to dance. He won the Blade Cup several times with his dance crew called "The Royal Blacksmiths."'''

Lou taught Cole at a young age to dance, though Cole disliked it and ran away. Cole then became a ninja and trained under Sensei Wu, while he sent letters saying that he had enrolled "Marty Oppenheimer School of Performing Arts." When Cole returned, he was under the impression that Cole and his quartet would replace "The Royal Blacksmiths." However, he later found out the truth about Cole being a ninja, and after being furious with Cole about lying to him, accepted it. He helped Cole gain his true potential.
