While explaining my character Ieono to someone I was with last night, they started asking a lot of details about the Watumno. I hadn't really gone into detail about their "true" appearance, so I thought I'd just draw a picture of Ieono in his neutral state.
This is the form Watumno are born into. I call it their "neutral" form, since they aren't using their devolutionary powers to affix other species' traits to themselves. Still pretty monkey-like, though!
