Breaking this out of the huge post as I really liked how he turned out with some conversation about it.
Max Health would be 6800, Color Priority of 
Symbiotic Slash 8
Carnage slashes out with a weapon made from his symbiote, damaging the target for 118 and causing it to bleed, creating 3 5 damage red attack tile. If there are 8 or more red attack tiles on the board, he downs the enemy, converting 8 red attack tiles to basic red tiles.
Level 2: Increases the base damage from 177
Level 3: Increases the attack tile damage to 11
Level 4: The attack creates 4 red attack tiles for 8 damage and decreases the number of converted red attack tiles to basic tiles to 7
Level 5: Increases the base damage to 236, the attack tiles damage to 10 and if there are more than 7 red attack tiles on the board, he downs them, converting 5 red attack tiles to basic red tiles.
Corrupting Influence - 5
(Active) Carnage spreads a corrupting influence throughout the battlefield, twisting the minds of those that would come to help. Transforms 3 team up tiles to red tiles
(Passive) Carnage uses the corruption of the battlefield to his advantage, feeding his symbiote and repairing damage to himself. At the beginning of every turn, if there are 12 or more black tiles Carnage regenerates for 44 health
Level 2: transforms 2 team-up tile to red and 2 team-up tile to green. Requires 11 or more black tiles to regenerate.
Level 3: If there are more than 5 red and 5 black tiles on the board, he also transforms 1 random yellow tile to red or green. Requires 10 or more black tiles to regenerate
Level 4: If there are more than 5 red and 5 black tiles on the board, he also transforms 1 random blue tile to red or green. Regenerates 15 health if there are fewer than 10 black tiles.
Level 5: If there are more than 5 red and 5 black tiles on the board, he also transforms 1 random purple tile to red or green. Regenerates 44 health in all circumstances
Carnage Rules! - 12
Carnage creates spikes all over his body and expels them with great force, damaging the enemy team as well as his own teammates. This ability does 83 damage to the enemy team and 44 to the other members of carnage’s team and destroys 3 random tiles, dealing damage, but not generating AP.
Level 2: Increases the damage to the enemy team to 195 and 108 to allies other than Carnage and destroys 4 random tiles.
Level 3: Increases the damage to the enemy team to 250 and 92 to allies other than Carnage and destroy 6 random tiles.
Level 4: Increases the damage to the enemy team to 445 and 120 to allies other than Carnage and destroys 7 random tiles.
Level 5: Increases the damage to the enemy team to 713 and 160 to allies other than Carnage and destroys 9 random tiles.
I added the tile destruction to help play into the chaotic nature of the character a bit…just fun stuff
