>>58827826Special Costumes are just another flavor of Seasonals except they are event themed, Variety also happen to be sort of limited units that can or not feature different trainer outfits or introduce new trainers even.
Special Sync Pair are usually free special pairs with whimsical reruns and availability, they can introduce alts or new characters, the alts often do not have different outfits but I don't think those are that important. Academy, AC or Academy Pair are Pasio Academy alts, A / Anni / Anniversary are also seasonals to celebrate the game anniversary.
SS is just a common Sygna Suit alt, just another outfit excuse for an event, but currently, unless they are Master Fair banners, they can unlock a 10/5 super awakening potential. A Sygna Suit can be freebie, genpool, pokefair or masterfair, SS is just an acronym for an alt, sometimes the SS gets an extra detail in its name to specify the alt and sometimes it's just a new basic name SS alt, see Elesa.
Then there is C for Classic, or Alt., those are used for a character's other canon official game alts, or they use other names for it (Classic, Dojo, Champion/Alt), Leon with Dragapult can be listed as BT Leon because it uses his Battle Tower alt.
Both Special Costume, Variety, Pokefair, Masterfair banners also use official ingame alts sometime, they can also introduce the trainers by their other aliases like Clive, Bellelba, etc, so far Masked Royal is the only exception being in the genpool since he was an early unit.
Also L for Lodge, the reward unit you can from interacting with a trainer at the trainer lodge. DC is the Damage Challenge shop unit, BP is the Battle Shop unit, both use tickets to be exchanged for.
