Infinitely variable in size, just like every other character striving for accuracy. All you have to ask yourself is if it looks good in your collection. I wouldn't mind seeing a Penguin transformer. It could be an homage to the BW character as well. It would be a sight to see. I think it could work. I've seen the CW Sky Lynx with legends and he looks good. Depends on how imposing you want your Sky Lynx to be.
