Scientist's Sketch Dump

My twin and I are stupidly obsessed with mad scientists and classic characters so enjoy this dump of them.
It features:
Victor Frankenstein and his Creature, Dr Jekyll and Mr Hyde, Dr Griffin/The Invisible Man, Abraham Van Helsing and The Headless Horseman.

A couple of scenes in here are just us having fun with the idea that all these characters end up hanging out with each other and how they would interact. (I am also trying to write a story for them but I can't focus on it right now because of classes).
