Twixxel, Mob, Grox and Verity :0

Grox: A wither skeleton. Grox has dark gray skin (or perhaps bones that look no different from a normal human, I don't know), completely black eyes with no pupils, resembling empty sockets. Grox wears a black tuxedo with a red tie around his neck and a pistol on his belt. He is ruthless by nature, adores all kinds of weapons (bladed weapons, firearms, etc.), and loves explosions, but he is quite cheerful with his friends and often jokes.

Twixxel is a half-demon. Twixxel has dark gray skin and completely white eyes (white sclera and white pupils). He has black hair that is tousled in all directions, and small black horns on his head. He also has something like a sticker or tag (?) on his hair with a ":)" design.
Twixel wears a black oversized sweatshirt and a white striped scarf with black stripes, and black fingerless gloves. He also wears black wide-leg flared jeans and black boots with white accents. And Twixel has a demon-like tail.

Mob is a half-enderman. He has dark gray skin and green eyes, and short, shaggy black hair. He wears a black bandana with a red edge that covers his neck and everything below his nose. (Only his eyes are visible; his bangs cover his forehead, and the bandana covers his mouth.)
Mob wears a black sweatshirt with red details and a red-trimmed hoodie that sits on his head. He also wears black baggy pants and chunky black boots with red soles.

Verity is a small yellow ball, the size of a palm. Its face resembles a wide, smiling smiley face. Verity is an assistant who knows everything about everyone in the world, essentially a virus (because it digs into player data and collects everything, so it knows EVERYTHING about every player).
Of all the players, Verity loves Mob the most.
