Maybe... it could also be because the dragon medallion increased his powers so much that it made his skin turn white and pale therefore making him look old.
I must say the Deception version is best. He has a very classic but not classic look to him. He has a mask but a helmet too. He has the traditional chest straps, but they're sort of furry. He has the belt and loin cloth, but it's armored. It's old but new. I love it so much, and it looks so good with the styles that Subby has in MK.
