Various One-Shots {Requests Open}

Hi, I know some/watch some stuff and am willing to write some stories based on:
-Marvel (MCU)
-DC
-OHSHC
-Seven Deadly Sins
-Undertale (+AU's)
-(possibly) Disney
-OC's (plus a heavy description on their name, personality, gender (+preferneces), ect.)
If you have anything else talk to me and I'll get back to you :3
I'm up to write anything, I just need a plot and character (+ info if ooc or and OC)
