I ended up appreciating Kapu-Tetefu's personality much more than I had expected, and I was happy that we saw Gladio again with his Type: Null, although it was a pity that he didn't see Satoshi and Lilie. Dusk Lugarugan looked good, but as an Iwanko fan, the evolution made me somewhat wistful.
I felt similar, especially since Rockruff evolved so early on. Couldn't you have stayed our widdle puppy just a little longer?
Granted Lycanroc actually keeping it's playful personality did ease that a little.
