Professor Okita
When Professor Okita's creation, Sojimaru, goes out of control and he tries to bring her around with a good, hard kicking, she responds by labelling him "trash" and blasting him with a flamethrower. It even causes Ichiban to make reference to the series' title (in the English dub anyway).
