Dry Bowser (Septallis) is a recurring antagonist in the Epic Mario Bros series. He was first introduced in the "Boot Camp" episodes along with his stupid nerd son, Dry Bones. He is manipulative, arrogant, abusive, and sadistic. He has an army of troops and his own boot camp. Later on, it is shown that he and his brother, Bowser used to fight until he fell into the lava and became a skeleton. His son also keeps running off on him to hang out with his friends. This fuels him to try to kill his rivals. In the episode, "Dry Bowser's Revenge" attempts to kill his son and Bowser Jr with his army and Kamek. However, Koopa arrives through a portal and kills Dry Bowser with a grenade, marking his final appearance in the series.
