Tendril (SG)

Tendril is a highly-intelligent plant-like man-thing dedicated to protecting Earth from those who would ravage it.

History
On September 21, 1986, a monstrous creature encased in an amber monolith was found buried in Big Sur national park. It was recovered by the government-funded Earth Corps, a geological sciences research team. The finding spurred honest industrialist Blackthorne Shore to clandestinely uncover a second monster buried elsewhere — a giant vine-like creature called Tendril, who attacked the amber block's public unveiling in San Francisco to release the macabre colossus trapped within, D'Compose. They rampaged through city streets before fleeing into the watery darkness of the bay.

The US government called it an "unwarranted attack by underground monsters" and promised the public it would never happen again.
