Lost in Space B9 Robot Antimatter Electronic Action Figure:

Warning, warning! Diamond Select Toys has taken their 10-inch rendition of B9, the friendly helper robot from Lost in Space, and transported it to another dimension! This Anti-Matter version features a fresh paint scheme, as seen in the episode "The Anti-Matter Man," and features lights and sounds taken straight from the classic sci-fi TV show. Lights on his head and chest blink constantly while B9 is on, and additional lights and "Anti-Matter" dialogue are triggered with the push of a button. Quotes include, "This is the opposite world," "So you're the goody-goody one," and I" don't need help from you, punk - get lost!" You can also manually raise and lower his head, open and close his claws, extend his arms and turn his torso to the left and right. He even has wheels so you can roll him around! Comes packaged in full-color window box with try-me feature.

Value: $70.
