One-Shot Minions

Where there is a numbers advantage, strength there is not.

The weak yet numerous fighters that can easily be taken out with a single hit. Like what the slidetext said, as there are so many One-Shot Minions, they aren't meaningless despite their weakness alone. However, One-Shot Minions have low defensive and offensive power, so the only way they can kill their targets is if they all attack at once. But since One-Shot Minions only really fight one-at-a-time style where, instead of using their numbers advantage to instantly overwhelm their already-outnumbered enemies, they throw themselves one at a time at the enemy to inevitably get killed in one hit. And that's why no one ever dies to One-Shot Minions.

If a Boss Fighter is present, the One-Shot Minions act as placeholders for the Boss Fighter. The One-Shot Minions might have been dispatched by the Boss Fighter so they can weaken the enemy and make the battle easier for the Boss. They're also commonly uniform in appearance, being identical and interchangeable with one another.
