There are still some Gen. 9 names that haven't sunk in yet. Just pulled up a list and honestly didn't recall "Crocalor" at all. Wants to think there's a member of the Varoom line named "Vivaroom." Chien-Pao is the only Treasure of Ruin whose name I can recall. Would probably struggle with most of the future Paradoxes had I not just looked at them.
Prior to Gen. 9, I still get hung up on Hattrem occasionally. Pretty much gave up on trying to remember Jangmo-o and family. Would probably call Pyukumuku "Pyukimu" or something along those lines. Pretty good on everything else I think, though I may have to check spelling on a few.
