In these fanfictions, Carmine and Sam are the stars. Carmine might bring in some light - hearted moments, while Sam is there to keep things in check. They are the ones who go through all the adventures, face the challenges, and their characters are developed further in the fan - created stories.
There's also 'Carmine and Sam: Brothers in Arms'. This fanfic is more action - oriented. It shows them fighting side by side against hordes of enemies. The author does a great job of describing their combat skills and the synergy between them.
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.
Well, it's hard to say for sure. The concept of 'porn-like' is quite subjective. Some might consider certain novels with excessive sexual descriptions as such, but it depends on individual perspectives and cultural standards.
In many places, 18+ porn comics are considered illegal. This is because they can have a negative impact on society and violate moral and legal standards.
