Kunzite
Kunzite was the last general Queen Beryl used. He was a teacher, and sometimes seemed a little more than that. His mission was to regain the ginzuishou, but he died in a battle with Sailormoon. He had sent an energy saber at her, but she deflected it back at Kunzite. He tried blocking it with his cape, but it drained away at him, and he died. He was probably the most powerful and most strongest general the senshi faced.
