I was searching for it names a minute by in yahoo search and found out its meaning:
Donatello – The brilliant scientist, inventor, and technology geek, Donatello has a reputation as something of a wise guy. He is perhaps the least violent Turtle, preferring to use his intellect to solve conflicts. He wears a purple mask and wields the bō-staf. He is named after Donato di Niccolò di Betto Bardi.
Raphael – The team “anti-hero”, Raphael has an aggressive nature and seldom hesitates to throw the first punch. His personality can be alternately fierce, sarcastic, and full of angst. He wears a red mask and wields a pair of sai. He is named after Raffaello Sanzio.
Michelangelo – The easy-going and free-spirited Michelangelo provides much of the comic relief. While he loves to read comics and eat pizza, this Turtle also has an adventurous side. He wears an orange mask and wields a pair of nunchaku. He is named after Michelangelo Buonarroti.
Leonardo – The de facto leader of the Ninja Turtles, Leonardo is courageous, decisive, and a devoted student of martial arts. As a strict adherent to Bushido, he has a very strong sense of honor and justice. He wears a blue mask and wields a pair of katanas. He is named after Leonardo da Vinci.
Hehehe Certainly I don’t like martial arts and I have no interest of it maybe because Janeth found the Leonardo similar to my name, ann vs. Leonardo can you hear the same rhyme?
