The look somehow expects us to see Blanka costumed as the giant dragon Nergigante. Fearsome and bestial for sure, but what in the world is going on here?

How is someone supposed to fight that and know what’s even going on.— vG /「 」 @ MiM@S2020? (@DeterminedSaito) November 7, 2019
This getup is coming Nov. 22 and will be available until Dec. 20. Presumably, one will acquire it by the usual method of completing unlock missions, begun with Fight Money.
The current timed alternate costume available in SF5AE is Poison’s Lady outfit from Devil May Cry 4. Players have another two weeks to pick up her look.
