Esteria has the normal Night Fury blasting abilities, including Plasma Blasts and a Lightning Shot.
Esteria has fair vision, pretty average for a dragon's, though she can see very well in the dark..
Esteria is extremely agile and quick on her feet, being aerodynamic and slim. Her reflexes are strong, she is able to dodge obstacles easily, that is if she can keep focus, which is rare.
Esteria is a very intelligent dragon, much like Toothless was. She also has a 'sense' for when trouble may be approaching, and she knows how to react rationally.
Esteria is extremely stealthy in the dark, she can fly and walk silently and almost melt into the shadows. In the daytime, though, she is much more vulnerable as light may make her stand out.
Esteria has razor-sharp retractable spines along her sides and back. These can slice through a dragon's scales with ease, but in order to do so she'd have to be very close to a dragon and expose her underbelly, leaving her somewhat vulnerable.
Being royal and a titanwing, Esteria has glowing markings that she can use to show dominance. She can also control the markings at will, which can provide light for any dragons who might not be able to see in the dark the way she can.
Weaknesses & Fears
Esteria, as mentioned, is easily distracted. This has ruined several stealth missions and attacks, as well as formal meetings, because she spots something else to focus on. She doesn't have a long attention span either, making it hard to have a long conversation with a dragon who may have concerns for their Queen.
As any Night Fury, Esteria is weaker in the sunlight. It drains her energy, making it so she cannot fly for long, and her shot limit decreases from 6 to 5.
Esteria can withstand heat, and she does have fireproof scales, but if she's standing in fire, holding in a plasma blast, cloaking, or any other thing that might cause her body temperature to rise dramatically, she would be weaker. Extreme heat for long periods of time would have the same effect on her that Direct Sunlight has, draining her energy and decreasing her shot limit. If she's exposed for too long she may pass out.
Death and Loss
Esteria has been exposed to death and loss her whole life, but after losing her father, a piece of her essentially broke. If she witnesses a death, even if she didn't even know the creature whose life was lost, grief can overtake her in an extreme way that she cannot control. It's similar to an irrational fear, she cannot control how she reacts, it's like the fear just takes over her body.
Trust and Betrayal
Esteria has major trust issues after being betrayed by Eddy, and she's never trusted humans ever since the story of her mother's death. She has a hard time working with unfamiliar dragons and humans because she doesn't believe she can trust anyone. She fears being betrayed by anyone she becomes too close with.
Esteria is overall an extremely insecure dragon. She believes she'll never live up to how amazing all of her friends are and how her parents were, and especially once she becomes Queen, she doesn't believe herself capable of doing anything. Though she is good at making descisions, she always doubts her choices. If anyone were to tell her that she is not good enough, she would believe them easily.
As most dragons, Esteria has a fear of eels as they cause her to be extremely sick.
Esteria, being jet-black and purple, is not super well-hidden or stealthy in the daytime. She can hide well in the shadows, but if she's flying in the sunlight, she's already slower, and additionally visible to any enemies.
Unwanted Aggression and Domincance
Esteria is very loyal and protective of those she calls friends, and would do anything to keep them safe. Often times when someone she doesn't recognize might be even talking to one of her friends, her titan side can "take over" and she enters what Nightfall calls, "battle mode," where she has unnecessary aggression towards another dragon. This makes her easily manipulated by enemies, for if they discover this flaw they can aggravate her into attacking others.
Esteria is not super strong when it comes to lifting heavy things, and can be considered physically weak. She does not spend much time on the ground, meaning her wings are very powerful, though if she is grounded for any reason she would not do too well.
Esteria cannot run long distances on land, becoming exhausted easily with little practice in that field of strength. She can run somewhat fast for short spurts of time, but that will follow with extreme exhaustion and the inability to fight.
Boom! 7 abilities and 11 weaknesses! I am proud to say, I think Este is not a Mary Sue! Of course, your opinions may differ, and dat's all gud, I only ask that you lemme know so I can fix her!
