FIASCO: Front for International Agents at the Service of Criminal Obstruction

Left to right, these are:

1. Eve - L

Not clear if she's an alien or a human female; she's an expert in martial arts and sharp weapons, as well as in stealth operations.

2. Bobby Kill Ya (huge guy in the back)

Half monster, half human, constantly trying to battle the monsters outside and inside his own self. He's pretty much a racist, but against monsters, this makes him very distant from the rest of the group. He has super-human strenght and detective skills.

3. Gay Killer

A little Alien enamored with Earth and Earth's classic fire weapons. He very often misuses words and expressions, that's why he opted for "gay killer" instead of "happy killer". His name always gets him into trouble, because people think he has something against homosexuals. He's the funny guy in the team.

4. The Megpie

A mysterious humanoid (product of an experiment) who can turn himself into clouds of dark vapor. He chooses to give these clouds the shape of small, black, bird-like figures, hence his codename.

5. Megpie's winged gun

Part of the series of experiments that produced The Megpie, the winged gun's name is Martin. He only speaks about work related issues. His rate of accuracy is 99%.

NOT PICTURED:

6. Pat Demon

He came from a dimensional gap opened by Bobby Kill Ya (who planned to go into other dimensions to kill ALL the monsters in all the universes). He was quickly identified (falsely, though) with a demon from Hell. He's actually very kind and acts like a teenager. His weapon is his disposable and hard exoskeleton which can be shaped into ultra-hard spikes (The armor lasts a few days, and once broken it has to wait for healing).

7. Black mummy

A Peruvian mummy brought to life to study the preservation of tissue. He (she?) specializes in camouflage and carries an semi-automatic, silenced shotgun

------------
The crystal orbs on the team uniforms are a powerful alien protein that grants the host a very effective healing factor against the most severe wounds and injuries. However, the protein is not a guarantee of invulnerability.

The Megpie rarely (never) uses it. Pat Demon refuses to use it (he belonged to a warrior chaste at his old home). The Black Mummy is, presummably, immortal, but he (she?) wears the orb anyway.
