If we're talking about sentimentals, all my Milotics. My Gen 3 Milotic, from my mother, named simply "Milotic" because...Because, to Rarity and Nurigami, all the way to my ORAS Milotic, SweetieBelle.
When it comes to Pokemon, it's my Milotic squad that makes me smile to most~

When it comes to Gen 6 in specific, it's my dog, Furfrou, that became the MVP. Competitively, yeah, it's not that good. But in game, he was basically unstoppable. Early game headbutts picked up the slack when someone else in my team was lacking, to the later game, where his damage dropped off, but his fur coat ability made him an ideal wall. I really love him~

Oh, and I can't forget my Volcarona, Mothra, or my shiny Volcarona, Mothra Leo~!

In Gen 6, I trained so many Pokemon, not for competitive reasons, but just because I could make esoteric and silly teams to battle with friends, including others on this board, so I came to appreciate a lot of Pokemon I used to not really care about. And I'm glad. The time spent breeding and grinding, while it was a chore, really made me come to appreciate a good hundred Pokemon I would've never noticed before.
I can't wait to do it in Sun~
