If you could choose just one ridiculous science fiction device, which would it be? Shrinking, enlarging yourself? Being invisible? Time travelling? Teleportation? Staying the same age forever? Morphing into an animal? Being indestructible? Having perfect grasp of every language ever known to man/woman?
I've decided against having x-ray specs set to cloth density strength, but only just, and gone for backwards time travel, myself. Always been a yearning of mine.
Yours? Please add any not listed above. Comic book powers accepted, it's all science fiction.
