Cristo (DQ4) vs Zapdos (PKMN): Heal-lock with Drill Peck -> Thunder. Think Cristo beats all the other birds, just dislikes his lack of lightning resist here. Kinda hope Cristo wins because he beats Id to me. <.<
Although this is obviously premature, discussion is fun and therefore how exactly would Cristo beat Id? Even should he live through Id's first barrage, his choices are either heal and face a double and therefore death, or Upper and assuming that completely nulls Id's physical damage, face a double ether spell and death.
I have less respect for Id's damage than you. I think we spelled that out pretty clearly back in Season... 14 or something. Might be a few extra levels or a few extra defensive equips, I have no idea. So yeah, survive DB, Upper, survive laughable Ether.
Alternatively you could just not allow focussing, like some people seem to do with Loki and Genevieve.
On Cristo resisting Wind, well, hmm, that's a point, although Drill Peck being Wind is frankly very weird. It's a strange situation, since many attacks introduced in more modern games that are Flying are obviously wind-like, but in RBY all the flying attacks involved, like, bird's beaks, while Razor Wind and Gust were Normal.
