Michelangelo is the youngest brother, also appointed to be "the one with the brightest fire" or with the most potential by The Ancient One. Master Splinter also claims a few times that Michelangelo obtains the most "raw talent" of all the brothers. Although, both Master Splinter and The Ancient One, say because of Michelangelo's lack of focus and interest in training, he will probably never meet his full potential. Michelangelo also claims many times in this series that he wishes not to be so serious and focused like his eldest brother, Leonardo. He also tells his other brothers to "chillax" and not be so serious all the time.
