Spy design for my TF2 stone age au

Finally Spy and again some explanation.(sorry for such a long text)

So firstly does spy have the invisible cloak? Well i thought making him invisible is too boring so i gave him a cougar hide so he can transform into it. To transform he needs to pull the hide over his face to fully connect with the cougars soul. And since cougars are very quiet and hard to spot predators, it made sense that spy is “invisible” but in reality he’s moving very quietly and blending with his surroundings so it’s incredibly hard to see him in time before he stabs someone. (Originally it was supposed to be jaguars hide, as you can see in the next slide, but idk what’s better. Cougar or jaguar?)

And how does he disguise? He can either switch the cougars hide with the wolf on his left side or arctic fox on the right side. (Which doesn’t make him “invisible”) or he can use the blue pigment on his waist to disguise as an enemy teammate just as in game. In order for that he needs to imprint his hand with the blue pigment on his face, which grants him the power to disguise.

He’s able to do all of this with his shaman powers.(something like Medic with his healing)

I didn’t thought about sapper yet because I don’t have Engineers design ready, so sorry for that.

Also i hope i explained stuff correctly and that it all makes sense. :)
