Collabs or other game themed Pokémon

I've been thinking many games promote different series or games by doing collabs with others, so maybe why not having certain collabs with maybe different series here in PRO as well?

Alternatively, have different series themed event mons. We already have from League of Legends a K/DA Akali Sneasel and Weavile, so maybe start from there and have all the other K/DA Champions (Ahri, Kai'Sa and Evelynn) as mons too for a full set. I think this second one could be more feasible license usage wise.

Adding a personal remark, I think it would be fun to have some Azur Lane themed mons. There could be, for starters, an Akagi and Kaga form Ninetales and Alolan Ninetales, Starter ships (Javelin, Laffey, Ayanami, Z23) forms for an starter set, as well as other Destroyer base forms that evolve into larger hull ships such as Cruisers and eventually Battleships or Aircraft Carriers from their factions. Just a quick idea anyways.
