It's another of the episodes featuring NOS-4-A2, so it's one of the better eps of the series. In The Slayer, the energy vampire's loose on Tradeworld sucking robots dry, but he's made the mistake of attacking one tough little tomboy's adoptive parents. Then Buzz and XR enter the picture.
The interplay between Savy and Buzz is highly amusing, with her streetsmart ways coming into conflict with the Ranger's more straight laced way of doing things. XR and NOS-4-A2 are golden in this episode too, with both getting some great lines.
The animation here is decent compared to other episodes, not too many errors or other goofs can be seen.
