User blog comment:Lord Loss/Discussion of the Week: Rare Species/@comment-28303251-20131202233844

I dunno about Frontier, but it seems rare species happen mainly for the flagship monsters. Coolest looking one to me is Abyssal, while Lucent was probably my favorite designed-wise...even though she's a massive pain to take down sometimes. But I like how it was more uniquie compared to the other 3 in Ultimate.
