Grand Bomber is one of the members of the Bomber Shitennou. He makes an appearance in the Bomberman Jetters anime as well as the game. His name is often confused as "Ground Bomber" which is easily justified because his attribute is earth.
Grand Bomber is the least intelligent of the group; easily being confused by what other's say. It took him a while to realize the Jetters were the people he had become friends with. Because he felt torn between his alliances to the Hige-Hige Bandits and the Jetters, he ultimately asked White Bomber to defeat him in battle, so he would no longer have to struggle with his identity. He was very good friends with White Bomber by the end of his life.
Grand can use a Clay Bomb which is a green bomb that has an earth attribute. When he summons his battle stage, his body becomes covered in spikes and his stage is a field where crops are planted. After some training, he was able to use the Brick Bomb which created a wall of bricks around him. Unfortunately it wasn't enough to overcome his weakness to fire. In the game Grand Bomber can tuck inside himself and perform a rolling attack that can withstand bomb explosions.
- His battlefield is a farm in the anime, while the game is an underground arena that has a similar design like the traditional Bomberman maze.
- While he is able to generate bombs in the anime, he never perform the rolling attack like in the game.
