Weeping Ghost

Boo Ghost Cat Halloween

Stark Industries? Who needs em? Dr. E. Brown Enterprises? What do they even do? When you're in need of some tech, you call Professor Elvin Gadd. Featured here is his familiar logo from Luigi's Mansion: Dark Moon, which adorned the Dual Scream communication device the good professor used to communicate with Luigi.

Watch your back, he will sneak up on you when no one is looking.

Sombra imagined as a kitty boo from Paper Mario.
