Ganta Gun (丸太・ガン, Ganta Gan): Ganta collectes his blood in his right hand and shoots it away (simillar to a bullet, hence the name Gun). He first uses this ability at the first day he was in DW. A boulder was thrown down with the intent to kill him and Ganta fires his Ganta Gun and crushes the boulder. He has trained his Ganta Gun to be faster and stronger with the help of Crow. The bullet of blood can also reflect against other objects, changing the course of the bullet.
Supersonic Ganta Gun: During his training with Senji, Ganta developed a new kind of Ganta Gun. This time, he makes the blood bullet smaller and slimmer. That way, the bullet is way faster and can be fired multiple times after each other. This also reduces the chances of anemia, because Ganta uses less blood that usually. Whereas the regular Ganta Gun is like shotgun, the Supersonic Ganta Gun fires like a submachine gun.
