Azure and 1x4 (1x1x1x1)

Azur is a creature that was once human, but was killed by a friend as a sacrifice to the cult.
Azure is a black-haired Robloxian with several black tentacles on his back that appear to drip some kind of liquid. He also has spiky black hair and one visible eye that glows purple. He wears a black, pointed hat with a purple glow on the front, likely inspired by Blizzard's Warlock hat, and a tattered black cape. A glowing purple Spawn emblem adorns his chest, along with the Phosphorus symbol, symbolizing his devotion to Spawn.
Also, it's Azur's hat that speaks for him, not him. That is, Azur himself speaks, but his voice comes from the hat's mouth.

A being made of hatred. He feels only hatred, anger, and the like.
1x1x1x1 wears a Domino Crown, with the letter X on one of the dominoes. He has long black hair and pitch-black skin, making it nearly impossible to see his facial features due to the blackness of his head. The only visible part is one eye, which glows with a bright red light. His mouth also resembles a clasp, but with sharpened teeth. A long, tattered red cloak is tied around his neck. 1x1x1x1 wears domino-shaped pauldrons on his shoulders. On his wrists are two green chains. Their chests are also translucent and green, with a Skeleton torso inside. They hold a Daemonshank sword in each hand, and black and green flames are visible from their bodies and swords. Their bodies appear to have a high-saturation filter applied to them, making them appear unnaturally bright compared to the world around them.
