I can't change my randomplayer character appearance ?

while wait() do
 	for i = 5,0,-1 do
		--Lobby Timer
		wait(sec)
		status.Value = i
	end
	local players = game.Players:GetPlayers()
	local monster = players[math.random(1, #players)]
	if players == monster then
		local mchar = monster.Character
		mchar.HumanoidRootPart.Transparency = 1
	end
end

My humanoidRootPart is always at 0 if i am the monster
