The last revision of Epsilon's Ref sheet by my good friend Tattorack (https://www.furaffinity.net/user/tattorack/ ) This version includes a tiny hooman for scale as well as a delightfully goofy mawshot while removing the old text blurb the first version had since it was no longer up to date after I decided to completely rewrite his story.

Additional info
Epsilon's exact height is 21'3" or 6.47m from the sole of his paws to the tip of his ears.
his length from snout to tail is 42'1" or 12.83m (Which is about as long as your average yellow school bus)

I'll try and provide a link to his backstory once I'm done editing and finishing it, right now its a 30 page long vorish mess that I'm really not ready to show to the public.
