I would love to believe that. Unfortunately we know it’s going to be a gorilla compliments Affleck. I really wanted a lemur like one too :/ or a tamarin
The affleck leak was contradicted (implicitly) by the Gameinformer interviews regarding Grookey. Masuda implied they were going to depict a primate not commonly seen in fiction. Gorillas are extremely common. Lemurs are only known in pop-culture from madagascar.
That, and there's still no way of knowing if the entire leak is true without any official reveals. That's why I was so contestuous regarding Eternatus and Meteodyna's names (again, Eternatus makes me think of an Atropal.)
The affleck leak has had confirmed elements, but it is not comprehensive. Leaks, no matter how probable, should not be taken as gospel truth, even if they are mostly confirmed. A few details could be off.
