How in the wonders of the world both Mr. Fury and Xmax have 4 characters!? *laugh* welp...
Character idea:
Bill (Left4Dead series)
HP: 200 (Decided due to 300 temp HP = 100 HP)
DP: 0
Base Att: 3 (Shove)
Items: Medkit - Heals 80% of missing HP. Renders helpless as you heal...
Pills - gives 30 HP... One use item...
Molotov - Lights nearby area on fire damaging nearby enemies...
M16 - His favorite rifle, ATT of 17-21, magazine is 50, Max. magazine size is 360. Shoots 5 of them per turn...
Katana: Emergency weapon... ATT of 70... Cannot attack ranged...
Ability: Shove - Shoves nearby enemies dealing miniscule DMG, but rendering them helpless for turn... (Bill attacks first in this case)
Ability: Shoot - Self explanatory - Bill shoots bullets onto enemies.
Ability: Throw Grenade: Throws his throwable weapon, be it grenade, dice or pebble...
Passive: War Veteran: May be paranoid, but lucky to him, he have easier time fighting (Weapon and unarmed ATT boost, but may do irrational choices...)
Passive: Carrier - Virus: Bill is partially immune to Green Flu's influence, meaning he doesn't get to be infected... However he's a carrier, and even his influence can infect people...
Passive: Zombie Killing mastery: Do more damage vs. Undead (1.25x)
One Time Ability: The Crew: Summons Zoey, Francis and Louis to fight for Bill for one battle...Zoey uses AK-47, Francis uses Military Sniper Rifle and Louis uses Auto Shotgun.
Or... If you think Bill is too many math
Alt. Kirby (Kirby Series)
HP: 220/220
DP: 66
Base ATT: 16
Items: Chainsword - It's more relying on items than normal Kirby... (Sword what was forged on top of Mt. Hectorius) ATT of 35-42
Ability: Basic attack.
Ability: Copycat: Inhale an enemy and copy it's ability.
Ability: Spew Star: Inhale an enemy and spew it out. Star may damage for 1.5x damage more than Kirby's base attack.

One-Time Attack: Fury of Pinky: Kirby Enters It's Rage state, buffing mainly it's weapon greatly for battle, but debuffing it's HP and Defense.
NOTE: Alt. Kirby is nothing compared to Kirby I've controlled in second chapter of TA... However, it entered the portal as it was annoyed by bossiness of Kirby...
