Right now I'm thinking this would fit the big dude from Temple of Doom. Heh.
I was wondering more about Fezzik from the Princess Bride, hence the Andre the Giant (7'4) question, or the cameo of Sun Ming Ming (7'9) as an unusually large monk in Rush Hour 3
(EDIT: from 2 minutes in).
The greatest increase in power this would grant over, say, Improved Stability, would be with regards to the Massive
weapons properties, imho. Overall, it seems like good fun, although I did have initial reservations about giving to humans a size tag that I'd previously understood as inherently, if not explicitly, larger-than-human.
