S-A-I-N-T Number 4

S-A-I-N-T Prototype Number 4 is one of the five S-A-I-N-T Prototypes in Short Circuit. Its whereabouts are unknown, but in one scene, one of the robots heads are being held by Benjamin Jahrvi when he and Newton Crosby are getting ready to find Number 5. Rumour is that it may have been Number 4's head Ben was holding.

Number 4 was originally meant to build a fully working model aeroplane with Number 5 for their demonstration and fly it around although this was a deleted scene from the movie it can be seen in the credits sequence at the end of Short Circuit.
