Cobalt/YMMV


 * Demonic Spiders: Ninja straddle this and Goddamned Bats, but Hamsters, Predators and Metalfaces all follow this trope to a Tee, each with their own unique way of killing you.
 * Hamsters can One Hit KO you with a single bite and take loads of damage. Luckily, they are unable to jump and are pretty slow.
 * Predators can do the same thing, but at range. They are even slower than Hamters, but gain a really high jump.
 * Metalfaces are the worst of all. They get the Shield Belt, powerful weapons, Jet Boots and all of the special abilities usually only used by the player. But that only makes sense since you are a Metalface.
 * Goddamned Bats: Anything weaker than a Ninja goes down in a few hits, is really easy to hit in the first place and spawns about 5 times as many actors onto the map. Particularly bad are Shrooms and Birds, who continue to spawn after most enemies would have been required to be killed twice over.
 * Memetic Mutation: "You Deaded"
 * Scrappy Mechanic: It is possible to punch rockets and other explosives back at the person who fired or threw them. Good luck trying to time it right. Made worse by the fact that the upgraded shield belt does exactly the same thing, and in order to punch the explosive in the first place, you have to put away the weapon you are using. In the middle of battle.
