Sometimes you see the weirdest things in comic books. Do you notice something familiar about this person?
No? Well, you might recognize this man and his crowbar.
I'm not entirely sure this was done on purpose; maybe it was just an odd coincidence, but Dr. Isaacs has a remarkable resemblance to Gordon Freeman, doesn't he? Oddly enough, I was unable to find any other images of Dr. Isaacs from his earlier comic book appearances on the internet. If you can provide one, please contact me and it'll be posted with credit.
Source for the scan is September 2005's Incredible Hulk #84, written by someone I don't want to mention, with artwork by Jorge Lucas. The Gordon Freeman image is part of Valve's promotional materials for Half-Life 2 and was sourced from the internet.
