The blue blur
Imagine adding a new cool alien in the book series just for it to never appear again.
And descriptions of aliens in Animorphs are always so funny, because most of the times it's basically: <<list of the limbs + vibe>>.
Since we don't really have much information about Garatrons and their homeworld I guess we can make any theories about them.
So! What if! They're so fast because they're on the same niche of their homeworld as insects on Earth? You know, like flies or roaches appear fast to us, humans, because of the size differences. Same for garatrons and... whatever giants inhabitants of their homeworld. It doesn't explain though why are they're still so fast on Earth. It's just funny to think of the world where insects are the same size as the gazelle... And are sentient... And are centaur-like.
Space deer and space gazelle comparison.
Very messy sketches, because my favorite pencil died.
