Dual evolution

Dual evolution is the slang term for the evolution creature cycle from DM-12 that evolve over a choice of 2 races.

Details
It is different from Vortex evolution released in the same set, as only one creature is needed as evolution bait.

While it has no official name, it was referred to as Dual Evolution in a Coro Coro magazine.

Each creature features 超 (Chō) meaning "Ultra" or "Super" as part of its card name, and are dual-civilization allied civilization cards.

They also feature support and increased power from the races that they evolve from.
