Technicality this day’s challenge is “the best form of transportation.” I’m going to cheat a little and choose two. One is a technology and the other is a mutant power. I have always found the X-Men’s iconic Blackbird. While a conventional means of transport the Blackbird is both in real life and in Marvel a cool means of transport. The original Blackbird was modeled after a scaled up version Lockheed SR-71. It was often destroyed during the many X-Men missions, at great cost to Professor X. It has also been upgraded with Shi’ar technology. The software for Cerebro was added as well as the addition of a cloaking device and the ability to fly in space.
The second form of transportation the “Stepping Discs” from Magik(Illyana Rasputina). She can mentally control these “discs,” which permits her to transport herself and others teleport “across interstellar distances or through time.” She must use the dimension Limbo as a midway point. She has teleported herself across continents, planets and even galaxies. Magik is also able to teleport through time and space. She has managed to teleport into the future and past by days or centuries. Obviously compared to the Blackbird, Magik’s discs are far more useful and varied. She has complete control of where she and others go, where the Blackbird is severely limited.
