How to make boss only respawn after teleporter is touched?

This is my script right now, for all I know it could be horribly wrong. Please help me. I'm trying to make a boss in my game only respawns after the player teleports back to the start. So I have the actual boss inside the folder of the teleporter so the teleporter is its parent? Idk here's the script!

name="Humanoid"

robo=script.Parent:clone()

while true do
	wait until script.parent.touched
	if script.Parent.Humanoid.Health<1 then
		robot=robo:clone()
		robot.Parent=script.Parent.Parent
		robot:makeJoints()
		script.Parent:remove()
	end
end
