Layeyes' Star Fox: Lylat Legacy is a Star Fox comic of fantastic artistic quality starting with the back story of Fox's rise to his father's legacy forming the Star Fox Team. It will eventually cover the entire rest of the Star Fox series (except Command)! It looks like every single canon Star Fox character ever created will be involved, especially our favorite blue vixen.
Follow the comic on its official webcomic reader page, updated with a new page weekly. Follow the ongoing development and concept art at the official Tumblr blog. Also, if you want to see how Krystal will look, here's all the posts tagged with Krystal.
