Deniardo (Den or Deniar for short) is a fith brother created by Bees Meliss for the TMNT/ TMNP brothers. His Seconds-in-Commands and Best Friends are Monaxus and Shadow. Their sister Sally is his girlfriend. He's really kind, carrying and always honest with himself, his brothers and friends. He's also very creative and artful, especially when it comes to P.P (Plan Preparing). However, he's very shy and sensitive and has a big fear for small spaces. He's also the middle brother in the family and twins with Raphael (Den is younger for 2 minutes). Despite his sensitivity and kindness, when someone tries to harm his friends and family, he never lets them to do that or get away with it. And sometimes, his anger can get out of control. Seems that he took after his twin brother… He also has a scar on his left eye which he got from Raph while he was fighting with him and his other brothers. While Shadow and Mona are a bit silly (idiotically), Deniardo never actually considers or treats them as "stupid". He considers and treats them as equals.
