Jekyll

Jekyll is a white scarred cat enemy found in The Junkyard that spends most of its time fleeing rather than fighting. When cornered with nowhere left to run, it attacks with a multi-hit melee strike, but its true threat is temporal: after surviving for 3 turns, Jekyll transforms into Hyde, a far more dangerous and aggressive enemy. Any damage dealt to Jekyll carries over to the Hyde form.

The transformation timer is the central mechanic when facing Jekyll. Every turn spent chasing it while it flees is a turn closer to the inevitable Hyde transformation, which produces a 20 HP aggressive enemy with a vicious 3-4 hit melee combo that charges directly at targets. The wiki's advice is blunt: "Kill them with extreme prejudice" before the transformation occurs.

Corner Jekyll early to force it to fight rather than flee, maximizing the damage you can deal before it transforms. Using knockback to push it against walls or obstacles prevents escape and creates easy follow-up opportunities. If the transformation does occur, the damage carried over from Jekyll means a well-damaged Jekyll becomes a much more manageable Hyde. Ranged attacks, knockback abilities, and Charm effects are all effective approaches for dealing with Hyde after transformation.
