>>10404709Cyrax should be just fine. In the amount of time he's been released I've heard of no issues with him, it seems to be only Sektor's candy red on the waistband that fades and thats fixable with some DIY stuff.
do watch for the silver paint though, its very minor but it can scratch onto the black. its just simply being gentle with him to avoid it.
other than that I can only speak for the early MK2 Ninjas, Raiden and Kung Lao having issues.
Should probably check my Kyo and Iori for the flaking pictured above
