An old idea I had for an Andalite TF sequence! I really wanted it to have an even number of panels, but couldn't come up with a satisfying sixth panel, and I never figured out who the characters were, so the sequence sits in my WIP folder until inspiration comes. Another part of it that I really like was the idea that each panel is set at a different time of day, with the first panel happening early in the day, the running panel taking place at sunset, and possibly the last panel occurring in the evening/twilight or at night. Come to think of it, I may have an idea involving lightning bugs?

As for why this TF is triggered by an injection and not a morphing cube - It's probably to ensure the new Andalite is wholly unique and not a clone of another Andalite, though the idea of an Andalite couple who are identical is also one I've played with. Also, if you get trapped in morph, you can't pick up the ability to morph again. If you become an Andalite by other means, maybe it's different!
