Pokemon Scarlet and Violet's Indigo Disk is filled with references to Gen 5 games and the Unova region as a whole, with some of them being simple easter eggs and others hiding something much deeper than that. The Indigo Disk's BB League has its own set of Elite Four members and a Champion, and most Elite Four members are confirmed to have ties with Unova in some way, with the only odd one out being Amarys - who could still be related to Iris, although this is not confirmed. Crispin is from Virkbank City and is often seen with a Magmortar, with his hometown in Gen 5 games being the only place where the Magby line is available. Another example is Lacey, who is the daughter of an Unovan Gym Leader.
