Familiars

Monsters created by Vitriol using his corallian power. With a sparkle of red energy, Vitriol animates lifeless matter and turns it into a creature bound to his will. The creature will generally display pink and green stained glass shards. It can attack by producing more of these shards, vomiting the stained glass in raw shards or in more elaborated shapes: swords, shurikens, spears...

While generally hostile, Familiars seem to follow the Command they were given at birth.

Familiars can be paralyzed for a time by Tilda, who can nullify corallian powers. When Vitriol's power is disabled, Familiars do no move anymore and their stained glass shards become gray.

Known Familiars include Floreal, Floreal 2, Klow, Monster Car, Floorhead, Checkpoints, Platform Monster, Rope Monster, Spear Monster, Chandelier Familiars and Bust Familiars.
