Master Splinter is wise, intelligent, and a skilled martial arts teacher. He is nearly always calm but despite his usually calm demeanor is not above rage, he will not hesitate to use his rage and anger to protect himself or his sons, however, again, he does always become extremely calm and level-headed, always making sure to be the father figure for his sons or be a good/loyal friend for his allies/friends. He is the quintessential calm, all-knowing wise master of all martial arts.
