Hmm ... this creature and its role in the battle for Gondolin with Tuor and Ecthelion has only been described in the Lost Tales and none of the story in which it takes part has been included in The Silmarillion. I would recommend not to assume this as canon lore and understand why the article on this subject on TolkienGateway has been tagged 'canonicity is disputed'. If it were up to me I'd not include this specific creature in mod lore at all. If ever wyverns/drakes and/or wyrms/dragons would be introduced I'd base the canonocity on the tale related to those that fled to the Northern Wastes and inhabited Withered Heath later on. Finally, note that Balrogs were less grotesquely powerful creatures in the Lost Tales than the ones described in the later, final version. Ecthelion was able to slay 3 balrogs in one strike during the Fall of Gondolin as described in the Lost Tales. That doesn't seem in agreement with the accounts included in The Simlarillion.
