"Dino-Riders" was a series of toys manufactured by Tyco Industries, Inc. and an accompanying cartoon series that focused on the battle between the heroic Valorians and the evil Rulons on prehistoric Earth. The Valorians befriended dinosaurs whilst the Rulons brain-washed them. Produced beginning in 1988, there were four series of Dino-Riders toys: Series 1 (released in 1988), Series 2 (released in 1989), Series 3 and Ice Age (both released in 1990). The larger toys in the line had motorized walking action w/the dinosaur's head swaying from side to side (though the Tyrannosaurus Rex's head does not). The toys were acclaimed for their highly detailed bodies/color. Offered here is Tyrannosaurus Rex, the biggest dinosaur toy produced in the first series. Battery-operated, it walks forward and its fearsome jaws open and close. The toy comes w/figures of Krulos (the Rulon leader), Bitor and Cobrus as well as "Full Battle Accessories" that consists of armor and weapons that could be placed on the dinosaur, effectively turning it into a walking battle station. This toy was the highlight of the first series of toys. Toy comes in its original 14x22x10" deep box w/front flap that can be lifted to view contents. Box has been opened and shows moderate wear to one end w/glue repairs to 2.5" tear and larger pair of 7" tears. Original cellophane window has 4.5" and 6.5" splits. VG overall, but box retains its shape and front still display nicely. Contents appear complete and NM-Mint.
