[Western Crossover] Grease, Don't Run Away!

The System gives me missions, and I take care of them, but... "Where have you gone, buddy? I can't find you! I can't do the main quest without you! Aaaaaah, what am I supposed to do?" I've arrived in a new world, but... "Why does this person look exactly like my dear Bruce!?" Someone calls me a dwarf. "Are you asking to die?" I smile as I draw my blade, ready to kill. [System prompt: You cannot kill anyone.] "..." My fingers grip the blade tightly as my smile freezes. "Damn System! One day, I'll break free of you!!!"

Worlds I might visit: Batman, The Avengers, Hannibal, Criminal Minds, Transformers. I don't know if I'll add more, and the order may not be as listed above.

P.S. A collaboration fic.

P.P.S. The pairing is still Batman, but note that Batman only appears at the beginning and end of this story. The rest of the time, it's just my Batman with the same face.

Note: Think of Batman as Ben's face x Have you seen BvS? The one who plays Batman, yes, my Ben x
