Flea

The Flea is a fast, self-destructive enemy found in all chapters of Mewgenics. At 2 Hit Points with 4 movement, it closes the gap to melee range quickly — but its SuicideMelee attack deals 4 damage to itself every time it strikes, regardless of its Strength stat. A Flea that attacks twice under normal circumstances will kill itself without any involvement from the player.

This self-inflicting mechanic defines the entire encounter: let it come to you. The Flea deals 4 damage per strike to its target as well, so it can hurt unprepared cats, but it cannot sustain any offensive pressure. Positioning a durable cat in its path lets it exhaust itself rapidly. Its predictable approach behavior also makes it an easy target to manipulate for ability farming when kept alive at the end of a fight.

Champion Fleas have 5 HP and deal 5 damage per hit — enough to survive three attacks before dying from self-inflicted wounds rather than two — but the pattern is identical. They remain one of the least threatening enemies in their chapters despite their aggressive movement speed.
