Terra

Terra is one of the main protagonists in Kingdom Hearts Birth by Sleep. Terra, along with his best friends Ventus and Aqua, is a Keyblade apprentice, and it is his dream to reach the rank of Master. Terra is calm and cool individual, though he is more than willing to sacrifice himself for his friends. Similar to Riku, Terra is often tempted by darkness and struggles to fully control it.

His name means "Earth" in Latin and in Portuguese. The official Japanese website refers to Terra as the "Vast Earth Protecting Bonds" (絆守る大地, Kizuna Mamoru Daichi).
