I am aware that there were many very strange creatures among the many books and comics such as sentient mountains. Some of these even became Jedi like Ikrit (an alien bunny like animal). While some strange creatures still exist in canon like sarlaacs, I cannot remember any strange Jedi. The closest I can think of is Yoda who is a very short humanoid.
Excluding Yoda, are there any canon Jedi who are not humanoid?
I will define humanoid as naturally having:
- two arms
- two legs
- No additional limbs besides those listed and (possibly) a tail
- a clearly defined head at the top of the body
- eyes, mouth, ears, or similar features on head in roughly the same locations
- roughly human size and proportions (why Yoda is explicitly exempt)
- solid organic (or similar) composition
Darth Vader counts as humanoid despite his robotic exterior and lack of natural limbs as he underwent extreme body modifications.
