"anti-pacifist" is a category originally created by the Super Mario Bros. speedrunner RoyLGamer. The goal is to kill all enemies who appear on the screen as stated on the branch. This means you don't have to kill an enemies that exist where you haven't visited, so I ignored some hidden stages which contain an underwater enemies. Also, enemies simply walking into a pit are not count as killed.
We made some exception to the rule because Buzzy Beetles are generally impossible to kill without using Power Star or kicking another shell, so even if you just stomp on Buzzy Beetles, we admit it as being killed.
Enemies not included: Bullet Bills, Flying Cheep Cheeps in 8-4 & Podoboos
Footnotes on some levels:
4-1: Lakitu reappears after a certain period of frames after it dies, and item blocks can manipulate its appearance timing.
5-1: At the end of the level, BBG was performed but it doesn't saved any time compared to doing normal flagpole glitch because the Bullet Bill didn't shot fast enough to reach the next frame rule. I believe it would be impossible to fire it more faster while killing all the enemies in the level.
5-4: There was 1 missing frame due to bad Firebar RNG and I never found it. I'd be very grateful if someone discover the solution of this unsolvable puzzle.
7-1: The last Buzzy Beetle was used for full-fpg and it emerges from its shell by the time the level is finished. Kicking the shell off the screen would be a clear and uncontroversial way, but I chose an improvements that could save more frames.
