Swamp Thing

1) Some stubborn geneticist is experimenting on humans, turning them into freaks.

2) A little guy saves a dwarf, gets acquainted with a swamp creature.

3) The geneticist catches the dwarf, who turns out to have escaped from his laboratory when he wanted to enlarge him, and kills him

Some guy promises to expose Arkane. Arkane needs a killer, and one that no one would even think of. Who is it? The Swamp Thing.
Arcane makes a mutant that looks like a Creature, and it kills the man. Everyone starts hunting the Creature, while Tressa's son tries to stop them. The mutant finally comes out, confesses to the murder, but before he can say that the customer is Arkane, he kills him with a pistol.

@AlexSok18: I don't remember anymore, but it's probably translated. But I can't remember where I found it.

Some kind of insect bit the overly curious Jim. While the doctors are trying to figure out what kind of poison it injected into him, the Creature gives him a transfusion of its "blood", which saves his life. And the insect turns out to be another Arkane experiment.

Arcane kidnaps Jim (the guy from the first episode) to ensure the Creature's non-interference in his next experiment: he released some kind of another mutant who can devour everything in the swamp. The first thing the mutant does is kill Arkane. The critter has to resurrect him so that Arkane can tell him where he's keeping Jim.
