Mark of a Hero

The Mark of a Hero (マークオブヒーロー) is a Keyblade that can be wielded by Terra, Ventus, and Aqua in Kingdom Hearts Birth by Sleep.

Design
The tooth of this Keyblade is the arm of a trophy and the hilt is a pillar which is a sign of Olympus Coliseum. The Keychain token is once again the Olympus Stone, used to signify the world's heroes.

The Mark of a Hero's name may reference "the ability to become a true hero", a common theme in the Olympus Coliseum storylines.
