So here's one character I drew a long time ago that I revamped a short while back. This big bat wyvern gal named Ultima. Here is a little more about her.~

Info: Ultima is what would be classified as a "Unique Species". A beast in existence that is unique and seemingly one of a kind in nature. As for what can be pointed out she is a sizable wyvern seemingly evolved to be bat-like in nature, capable of wielding blue fire which in itself is a rare sight she is considered to be notably powerful but to what extent is relatively undetermined. Her nature while not entirely determined seems to follow mostly a expected pattern. One of being a hunter who prowls out of her nesting grounds at night and remaining within her nest during daytime hours. The nest itself being a large ruins of sorts that pre-dates most modern structures within the world. Documented encounters of her noted her being quiet in nature and seemingly elusive. The name "Ultima" Seemingly derived from old scriptures found within these ruins suggesting she has existed within for a notable period of time. Though exact age of Ultima in question has not yet been determined. The marking on her stomach appears unnatural in nature and could hint at something more about her. This however is also undetermined. Aggression has yet to be properly noted as of yet but caution is highly advised given the nature of her and the blue fire noted.
