Awakened Ent Remnant

Ents were treelike creatures, and while their reproductive process is unknown, some "seeds" survived under extremely unique conditions. The creature that grows from these seeds is... different. Hundreds of thousands of years of preservation, and an environment that is no longer completely hospitable for them, have rendered what used to be a sentient Ent into nothing more than deadly psychic monsters under permanent agony, feeling nothing but feral hatred. The two most dangerous abilities an Ent remnant possesses is producing injectable xenogerms on the fly, causing their victim to mutate rapidly and violently, and manufacturing bio-carbines from local materials, which they operate with finesse using many flexible branches.. Extremely dangerous and potent fighters, but vulnerable to human firepower; flamethrowers, experimental vacuum bombs and, if all else fails, atomic warheads will make short work of them.
