Congrats you are hired to be a comicbook writer. Just think about all the good superheroes and super villains and just write about things that they do and or would do just do not copycat or steal someone else's idea or else you might loose the job.
Just keep practicing and working and someday everyone will know you and will want to meet you and want to be you. Also your brain will have more ideas and might improve a thing or too.
Doing this could also lead to many good things in life and might cause some good things happening in with the stories that you write about.
