This is Samurai Foxy, he's from a set of cutscenes that you'll find in Five Nights at Freddy's: Ultimate Custom Night. He has a similar design to Foxy from the same series, but with some minor differences and more muscles.

This skin in an updated version of the previous Samurai Foxy skin that I uploaded about 3 years ago. It improves the muscle design, facial features, and a complete redo of the color pallet, using the character's actual colors from the game. I know I said before that I'd try to make a better version of the skin at some point, and I guess that time is now. It's nothing crazy, but if you asked me, I'd say this is a pretty nice improvement from the first version.

Time for me to disappear for another 3 years, but until then, enjoy this skin!
