StarterCharacter Interfering with Script?

So, I have a problem where, when a player joins, it checks if they have a certain thing, and if they do, gives it to them, but, if they don't, checks if they have another thing. If they don't have anything, then ends the script. The middle is cut out because it's so big and I know works. Anyway, the script stops working on line 4. WaitForChild(). It might be because I have a StarterCharacter.

game.Players.PlayerAdded:Connect(function(plr)
	print("PlayerAdded")
	local Char = plr.Character
	Char:WaitForChild("Humanoid") --This is where the script stops working, even tho my character does load humanoid. Maybe because I have a StarterCharacter?
	print("CharAdded")

		--A big block of code that I know works is here
		--The functions for the armor are here

	wait(0.1)
		if plr.Armor["Oblivo Armor"].Value == true then
			print("ObTrue")
			ObArmor()
		elseif plr.Armor.Titanium.Value == true then
			print("KnTrue")
			KnArmor()
		elseif plr.Armor.Steel.Value == true then
			print("StTrue")
			StArmor()
		elseif plr.Armor.Iron.Value == true then
			print("IrTrue")
			IrArmor()
		else
			print("NoneTrue")
	end
end)

Help?
