Hello! This is my first post on a forum in like 90 years so if this is unpleasant to read please tell me! Also, criticism would be nice!
Anyways,
LEVIATHAN
An Australian ex-ASIS covert operative, discharged after stealing the prototype to an advanced mining tool alongside stealing a portable fusion generator, Leviathan is the terror from below; armed with a deadly laser cannon, the eponymous Leviathan, and an ammo station to stock up friends.
Appearance: Has a thin, generically attractive face with prominent cheek bones, with a blond shaved-sides-hair-on-top hairstyle (the macklemore, if you will). A light fuzz on his face, with a nifty, pale scar on his forehead. Youngish looking (30 at the oldest). Wearing a military jacket a size or so too big, with a bullet-proof vest and a button up shirt underneath. Wearing tight jeans with army boots. Leather gloves. Main colour is jacket, secondary is shirt and pants.
Personality: Kind of crazy, with many mythological/biblical references scattered through his taunts and when using the cannon.
Class: Fire support
E Ability: Ammo Station.
Q Ability: Leviathan. The leviathan is a huge, shoulder mounted laser cannon; think the Spartan Laser from Halo, if you will. It requires a charge up to be used, acting as a lighter, more portable Kira. It fires a beam in a single line, totaling at 250 if the beam makes a direct hit (ie, to OHK everyone, but if it clips Rhino or Fragger they might survive), It is capable of three- or four-shotting the EV, but is specialised in quick removal of a large enemy, such as a Rhino. It has two charges at any given moment, allowing it to be used relatively quickly, but not without aiming. The beam is quite forgiving, so long as the enemy is like, near the crosshair.
Effectively, Kira for corridors and far less noticable.
Primaries: Assault rifles
Secondaries: Pistols
Health: 110
Speed: 420
The values are all subject to change! thanks for any advice 
DOMINO
A New Zealand ex-riot officer (she can’t exactly be a cop and a merc) who quit to settle down and raise a family; unfortunately, her desire for justice was overwhelmed after learning of the dirty bomb attacks in London. Probably deluded, using her unique fold-out electric riot shield and her hard helmet, Domino won’t be falling under any circumstances.
Appearance: Older, gruff, with a tight black bun at the back of her head. Dark, angry eyes and with teeth often gritted. Also, wearing a riot helmet with a transparent visor. Wears a short sleeve shirt (with primary camo colours) with a black ballistic vest over it. Baggy cargo pants, with kneepads and armoured boots. Has a huge metal tool attached to her left arm that folds out to become the shield. The word riot is sprinkled over her gear.
Personality: motherly, yet professional. Very hard on people who aren’t good, but praises excellent soldiers where possible.
Class: Soldier
E Ability: Hard hat: Domino has a helmet on, which reduces the headshot multiplier slightly (can’t think of a value). Helps her tank.
Q Ability: Electroshield. Domino’s shield is a huge, foldout piece of tech infused with energy. Has a set charge time, which is reduced when hit. When left clicking, Domino shoves forward, shocking enemies a little, which uses charge. When right clicking, she ‘braces’ it, which reduces energy loss at the cost of move speed. The shield will absorb ALL damage (and pickups) while it has charge. It is wide enough to cover both Domino and partially her friends. This would be useful to make a push (because you won’t get killed on the way). However, the shield has no combat ability, and therefore Domino wouldn’t be able to use it in close quarters.
Primaries: Shotguns
Secondaries: Magnums
Health: 150
Speed: 385
Basically, a pure tank; no fancy grenades, and a viable counter to both Rhino and Fragger. Plus, a female tank! Not all women are tiny and fast.
FLASH
A French GIGN Operator turned self-proclaimed hero, Flash is quick and efficient; armed with his experimental EMP charges and a toolkit to disable (or plant) high explosives. You won’t see him coming until he’s gone.
Appearance: Small, with a get-up similar to GIGN uniforms, except personalised; covered in lights and gadgets, as well as his own baseball cap (with his name on it, no less), no sleeves, and a scarf. His face is small, and thin, with wide eyes and a squared jar.
Personality: Egotistical, but heroic. Very professional when needed, otherwise grandiose and over-the-top.
Class: Engineer
E Ability: EMP Charges. A grenade that detonates on contact and disables all enemy electronics (landmines, turrets, health stations) for 30 seconds or so. The person who placed this is only alerted if they see it; otherwise, the game tells them that it still works. The charge has a sticky bomb throw distance. Flash can only carry one at a time, but has a 20 second cooldown, which forces it to only be used for rushes or strategic use.
Q Ability: Objective Specialist
Primaries: Shotguns
Secondaries: Machine pistols
Health: 90
Speed: 450
The much-wanted emp merc, bundled up with an engi; built for rushing and strategic support.
Any thoughts? Thank you.
