GeroVort, creator of previous excellent Krystal fanart, has come up with a novel concept for Krystal. What if Krystal, who is from a different planet than Fox McCloud, actually was physically alien compared to him, rather than simply having a different fur color and psychic powers? The result of these questions lead to the creation of a truly Amazonian Krystal who is twice Fox's size and has a different facial structure. You can see in the scenes below how GeroVort shows the two characters meeting and interacting in a much more "first-contact" way than in the games. The different armor and staff designs are a nice touch too.
