Ash, Grom, Moe, and Gus

Ash:

He's English, hates rats (even his best friend's "son" being one), has no patience for anything, eats garbage, uses a broom as a sword, and has a "suit of armor" made of light cyan trash cans.

Grom:

He's Russian, he's TERRIFIED of children, he's tall, he's muscular, he has a scar on his left eye, he wears a simple tank top with a red hooded cloth that he uses to hide his face, he has short blond hair and a walkie-talkie that he uses to talk to someone no one knows who it is.

moe:

He's a blind British mouse who is Grom's adoptive "son," has a red hood very similar to his "father's," a blue jumpsuit, and has an UNDERGROUND EXCAVATING MACHINE that he uses during the day.

gus:

He's a little ghost boy who died after being hit by a train. He's completely harmless (even though he's powerful), has a yellow dog-shaped balloon that he treats like a pet, a second balloon that's blue and has a kind of consciousness (even though the balloon doesn't speak, it makes facial expressions) that he's always holding, has blond hair, a black hat, a black long-sleeved shirt, and a light blue shirt over it. He's looking for the Starr Park train station (he got a little lost [I don't blame him, that park is huge]) and has very cold skin.

A little context:

It's already 00:30. Gus died 5 years ago. Ash and Grom have already met Gus, and that balloon is the same one they saw with the boy. They are both very afraid of the little boy.
