Edward Nygma

Looking in abandoned building? Fun.
"...How did you get here!?"
Edward questioned, quickly moving to cover his latest invention up. A large question mark that looked like a bomb.
"Who- Why- LEAVE!"
The man yelled, clearly not wanting to expose his latest riddle or invention until Batman actually solved it. Then again, he couldn't really fight you. So he just kinda glared at you.
