Awesome / Drill Dozer

• Jill single-handedly destroys Croog's ultimate weapon: the Doom Dozer, a building sized dozer. That's more than enough proof she's the boss of the Red Dozers.
• Drill Dozer has you go through an entire game using a drilling mechanic, and for the final boss fight, the Dozer loses all of its drilling gears. The heroine, a school-age girl with pink hair, then proceeds to punch Croog right through his blazing energy shield for a one-hit kill, bisecting his mask and launching him off the chair in the process. It helps that you'll most likely have to do this while Croog is charging at you.
