which TMNT is which and whats the difference....?

Leonardo wears blue, uses katana.

Michaelangelo wears orange, uses nunchucks.

Donatello wears purple, uses a staff (bo).

Raphael wears red, uses sais.

Traditionally, Leo is the leader, calm, cool headed. Michaelangelo is a party boy, gets himself into trouble by not thinking ahead.

Donatello is the brain of the group, invents gadgets.

Raphael has a temper, often rushes into things without thinking.

The four turtles are Leonardo, Michelangelo, Raphael, and Donatello. They where different colored masks and each turtle fights with a different type of weapon.

Leonardo - blue mask, katana

Raphael - red mask, sais

Michelangelo - orange mask, nunchucks

Donatello - purple mask, bo

That's an interesting question!

That's a good question, I was wondering the same thing myself
