Feel free to post your ideas on how to improve a character you enjoy..
1) Keep Marvel Ares the same powerset except make him kind of like a stronger version of DeathStroke. A true tactical genius who wins fights almost every time, not by overpowering, but through tactics / prep and superior fighting ability. The God of war should NEVEr lose a fight or ever be outprepared in combat....
The only problem with this is that in mythology Ares isn't the only God of War. Athena is the Goddess of tactics, strategy and prep when it comes to war. Ares was more the representation of the savageness and brutality of war.
