The Slinker

The Slinker is a corrupted gem that first appeared in "Reformed", serving as the episode's antagonist.

Appearance
It resembles a dark, flowering plant. The monster consists of four dark blue petals, which act as its mouth, and are light blue on the inside. Each petal also has five thorn-like projections nearing the tip. The petals are connected together by a darker blue bulb that tapers to a point. The bulb is connected to multiple vines used as appendages, with two vines having a leaf-like structure at the end. Though not seen on the show, the promo art reveals that the monster has a square shaped gem found inside, at the middle of the bulb where the petals join.

Abilities
The Slinker is a very sturdy creature, able to withstand multiple hits from Amethyst and Garnet. It is also able to tunnel through the ground forming circular tunnels that lead into different parts of Amethyst's room. Its vines are very prehensile, able to entangle enemies with a tight grip to the point of constriction. It also has great physical strength, able to force Amethyst to retreat to her gem with a single bite from its "jaws".
