You were sent from the future to protect Sarah Connor, because a terminator modeled T-800 or cyberdyne system model 101. You must protect Sarah at all costs even if that would risk your whole life. The terminator won't stop until has terminated their target, it can't feel pain, it can't feel remorse, it is a cyborg, machinery inside, covered by living tissue, they are hard to spot since they look human. Before you go on your journey to protect Sarah.. You should probably find clothes.. Since you can't wear fabric when going to the time machine
