10 Video Game Enemies Worse Than Any Boss

Serving as a prequel to the original Resident Evil, Zero has Rebecca Chambers reluctantly allying with an escaped convict called Billy Coen to take down Umbrella's latest batch of zombies. The survivor horror has many creative bosses, including a zombified scorpion, a bat, and a centipede.

Even though these conflicts are no picnic, nothing fills players with dread like the Mimicry Marcus. This enemy is composed of hundreds of flesh-eating leeches, that form into a humanoid shape. These bloodsucking horrors can elongate their limbs, so keeping your distance is ineffective. 

Rather than using conventional weapons, it's more sensible to stock up on combustible items like Molotov cocktails, since these leech men aren't a fan of fire. However, cocktails are limited so you better not miss when one of these creatures starts closing in on you.

Even when this sinister adversary is fatally wounded, it's not done. Just before the Mimicry Marcus dies, it wanders in the player's direction before imploding, causing heavy damage. Leech Men tend to appear in tight spaces so it's difficult to avoid them when they go kamikaze.

Just to amplify the tension, you always know when a Marcus is nearby since its presence is accompanied with a high-pitched operatic melody. These enemies will be the death of you many times over, so your heart is sure to sink every time you hear this shrieking ballad.
