Earthquake is a character from the Samurai Shodown fighter games.
Probably the biggest human character in the history of ever.
So naturally he's a huge (^_^) influence for Oni2's Mr. Big.
There's a really cool ZBrush model of him by A. Kotelnikoff 
And that's about all you need to know for now.
P.S. Mr. Big was imagined before I became aware of Earthquake. geyser
