It could be an ancient evil that has been awakened by the chaos of the two universes colliding. This entity is powerful and has the ability to manipulate the very fabric of the Gears of War and Ben Carmine's world. It wants to destroy both worlds and reshape them in its own dark image, and Ben Carmine and the Gears have to figure out a way to stop it before it's too late.
One idea could be that Ben Carmine gets transported into an alternate dimension where the Gears of War universe has some strange new threats. He teams up with the Gears there, using his skills from his own world to help fight off the Locust horde. Maybe he brings some unique weaponry or tactics that the Gears haven't seen before.

One common theme is loyalty. Carmine is often depicted as being loyal to his comrades in the Gears of War fanfiction. Another theme is survival, as he has to fight through the harsh battles in the game's world. And his relationship with his family, if it's explored, can also be a theme.
The Locust Queen could still be the main antagonist. Goku would see her as a great threat to the people of Sera. His sense of justice would drive him to take her on directly.
In a lot of the fanfiction about Benjamin Carmine, survival is a big theme. Given the harsh and dangerous world of Gears of War, Carmine has to fight to stay alive. Also, redemption can be a theme.

For example, if he was seen as a bit of a coward in the game, a fanfic could show him overcoming that fear and becoming a brave soldier. There are also themes of loyalty, to his squad, his family if it's mentioned, and to the cause of fighting the Locusts.
Odin could be the main antagonist. He is a powerful and manipulative figure in Norse mythology. He might see Kratos as a threat to his power and send Baldur to deal with him.
