Favourite plot twist: Ammy's parentage, paws down. Relatively strong contender: Gino's backstory, nya~ :3

Rationale: despite the fact that it was (more or less, compared to eg.: Styx's backstory) fairly promoted in development stage, it managed to keep a quite strong sense of twistness and of (out-of-universe) lector teasing. Also I feel it is the twist that helps extend its character the most of all the ones in the list ecept perhaps Axel's backstory, but unlike Axel's this one felt better integrated to the ongoing storyline.

As for Gino, come on, there you have a Salamence who acts like a kitty. How can you not love that to the point of wondering how such a weird cuteness was even possible in universe? And the answer, once found, makes so much sense for the kind of world we're playing with.

(Besides, it gets extra points because it does fit nicely with the perception of the character when he noms Rattatas whole, nyan~)

...Did I mention that I liked the reveal of Ammy's parentage?

-a Dunsparce wearing glasses and a fake nose enters the thread-

Uh...hey. I'm...um....Yreve Otimem. I think Ammy's reveal was really cool. Um...yeah.

-flees-

I think my favorites would be #1, #2, #3, and #5.

Alduin :3

Gotta go with Umbra and Lina's origins. The original, the best in my mind, and moreover the one I've seen played with most and have the most potential for stories. I like open ideas like this, so it gets my vote.
