Let's be crystal clear, I like exploring new concepts, to actually come up with new ideas and create. That's the fun part along with my freedom. I would love to make every fan happy with my "personal" adaptation of this characters, but unfortunately that is a little unrealistic.
I found this BG in google, under "ice cave" and painted the crystals to match Crystal Kid.
The character, Bobb Kohan was a young boy on a family picnic on a glories summer day when puberty kicked in. Bobb's mutant power to create crystal or transmute other objects into crystal surfaced... turning his grandfather into a statue of crystal. When he became old enough he went straight to enjoy the camaraderie of other super-powered youths and have a shot at the Legion of Super-Heroes membership as the Crystal Kid. Crystal Kid, along with Lamprey and Nightwind trained with Wildfire. After Wildfire trounced them in a sparring match, he confided in the three his true tragic past. A past he had not shared with other members of the Legion. Crystal Kid's confidence was boosted, and he, along with Nightwind and Lamprey decided not to give up trying to join the Legion. Bobb was always willing to learn, but also too quick to action, a trait that has gotten him into more trouble than it ever got him out of. However this same thirst to learn drove him into the Legion Academy, here as a student he would hone all the skills needed to become a true hero. While concentrating, Crystal Kid can create constructs made of crystal. He can use this in a variety of ways, offensively or defensively. However, these constructs quickly disappear if his concentration wavers.Between the end of The Magic Wars (Legion Vol 3, #63) and the grim Giffen version (Legion Vol 4, #1), there was a five-year gap during which a so-called crisis called Black Dawn occurred, resulting in the disbanding of the Legion. During this period, many new Legionnaires joined up, including Crystal Kid.
