Sergio
Great Hero Segio was a dragon active during the early conquests of Queen Chrysalis.
History
Revered as a great hero, Sergio as a prideful and vain dragon who took care of his appearance far more than a typical dragon. Prideful in his looks and abilities, Queen Chrysalis tricked him into displaying his powers and posing for her, so she could attack him when he was vulnerable. Using Nitwit as a weapon, Chryalis pierced his wings and caused him to fall into a volcano.
In the present, Chrysalis told the story of her battle with Sergio to the Mane Six and Spike. When they were mortified by the events, Chrysalis assured that he was "probably" fine.
