From what I know The Combine is basicly a virus, when they get their hands on 1 thing they win, instantly, like 1 stupid Rick from Rick and Morty, 1 Infinity Stone from Marvel, etc..
He is a Crossover hero so I doubt that this suggestion would be good, this is The Ebony Warrior, he uses a Ebony Warhammer from Skyrim, his raw heavies are Unblockable but slow, and his lights are fast but do little damage, his Zone attack is like Black Prior's but the Ebony Warrior pokes them with the Pommel of it causing them to stagger where he can follow up with a light or Undodgable Heavy, his feats include
Feat 1: Reatoration, he uses restoration magic to slowly heal 50% of his own HP or a team-mate's HP, he can be interupted and that stops the healing, it has a cooldown of 400
Feat 2: Raise Dead, you are able to remotely revive your team-mate at 25% HP, but the revive is slower and has a cooldown of 200
Feat 3: Grindstone, when unlocked the Warhammer does a small amount more damage
Feat 4: Summon Storm Atranoch, summons a Storm Atranoch from Skyrim that has it's own level 2 AI but hangs around the Ebony Warrior, it lasts for 60 seconds, with a cooldown of 500
The Ebony Warrior also comes with a new Shouts system where the shouts can be swapped out at the begining of the match
Shout 1: Flame Breath, does small amount of fire damage, like 10% HP, but has a cooldown of 300 from the start of the match and a cooldown of 500 when used
Shout 2: Unrelenting Force, launches the enemy backwards pretty far, like Juren's throw, it has a cooldown of 300 from the start of the match and a cooldown of 400 when used
Shout 3: Dragonrend, when used on the enemy it causes them to stuble and gain 3 debuffs, such as slower movement speed, less damage, and slower stamina regen, it has a cooldown of 300 from the start of the match and a cooldown of 300 when used
Feel free to critique it, I just wanted to share my idea
