could they also be partially based on the 7 deadly sins combined with other concepts too ?

2 cover legendaries + 4 guardians + 1 marshadow may rappresent the 7 virtues

i mean, it's a legit theory, isn't it?
especially after the creation theme in gen 4, life cycle in gen 6, more human aspects with the gen 4 pixies, reasons and shit in gen 5

they may indeed end being partially based on the abstract concepts that are the sins, manipulative and tricky
