Metropolitan Era Monsters are Mythic monsters from Metropolitan and are way more powerful than their predecessors. These monsters can only be ranked up by using their own cells, nebula, or Nectar. They also have the ability to perform a cap breakout, allowing them to rank up to intermediate steps with less Nebula/Nectar.

They also unlock a special slot for Obscure Talent, which can only be equipped by Corrupted Mythics that have been ranked up, from Rank 1.
