just got to think both Indra and Ashura had a deity they could summon. this leads me to believe that maybe Indra and Ashura's sucessors who have fully awakened the Rinnegan(like Madara) can maybe summon an even stronger more powerful creature or maybe the susanoo and Battle avatar are just two halves to one creature

also since ashura had a technique simular to susanoo you think he had the Anti thesis to Amaterasu(maybe water that can put Amaterasu out)
