AW, I just love the happy face, & the fact its pretty clear (to me at least) that this is supposed to be TRio's Meowth, or I think it is him (the being on two legs, holding something very human-like with his paw).
I've NEVER had any trouble picking my fave: I had JUST become a cat lover, not a year or two before I first figured out what Pokemon were, & the minute I saw a plushie of him, my first thought was "they have cat types in this thing? huh... " & after a couple episodes, it was pretty dang obvious. <'3
I ALWAYS have one on my team, but one specifically 'made' to represent TRio's (aka hatching eggs until I get a Quirky/Naughty one with in-character traits ("loves to eat" being an example), & ALWAYS making sure its a boy!), & I ensure the FACT he never once has Pay Day as one of his attacks.
Reason should be easy to spot: I want him as my starting Pokemon, or at LEAST one of my first I ever get, but the ULTIMATE dream is to for him being my starter, & not hard at ALL to do, either! Just a matter of showing (not just telling!) him how much I'd spoil & pamper the little cat to the point where we'd pretty much be NO different from Ash & Pikachu theirselves.
