The Blasting Space Sled was a vehicle used by Brainiac.
Brainiac stored a space sled on his ship when he invaded Apokolips. He later used the sled when he traveled back in time from the 31st to the 20th century.
On the commentary of "New Kids in Town", Bruce Timm mentioned the toy people asked them to use the sled. The vehicle came with Kenner's 1996 "Evil Alien Brainiac" set, though in proportion to the Brainiac figure, the animated sled is bigger than the toy.
