Jack Kirby's 70s tenure at DC saw the creation of the Fourth World, his inter-connected maniac masterpiece that laid the foundation for much of the DC Universe's mythology. One of the lesser creations in that span, the Forever People, did at least have a sweet ride. The Super-Cycle used the technology of New Genesis to transport the heroes through the universe with Boom Tubes, but the biggest part of it was that it was a sentient being, and it was horny. In an issue of Young Justice, the Cycle gets its pon farr on, finds another one, and makes a baby cycle named... Kirby. Aww, how sweet.
