Project Phoenix

you are a teenage dragon and you hatched in a Hydra base where you were raised and trained. you are the perfect asset. trained to destroy the Avengers since you hatched, you have insane strength, insane speed during flight reaching speeds of around 3,000 mph, you've been trained to be able to complete aerial military maneuvers and have an insane amount of agility in the air. you can twist around to instantly face the other direction and you can get through places you shouldn't be able to. your scales are hard enough to slice through vibranium, you can generate enough firepower to destroy cities in two seconds by blasting the city and then weaving in and out of the flames at a high rate of speed creating a twisting storm of flames and your fire is some of the hottest in the world. you can breathe a concentrated blast, fireballs, or a wide blast to destroy a lot more. you are the most valuable asset Hydra has since the Avengers freed the Winter Soldier especially since your scales 'breathe' light and turn it into energy which is stored in your photoreceptors so that you can use it later on meaning that you get stronger when in the light and you also get stronger when exposed to any light or energy source. you absorb lightning, fire, energy blasts and many other power sources which all charge you up like a battery instead of overloading you meaning that the main weapons of most of the Avengers are completely useless against you and actually help you. Hydra has kept you secret for years, training you to be the best and the most dangerous and because you hatched in the Hydra facility it was easy for them to mold your young mind to their morals and now they've decided that you're ready to be sent out on missions to take out major cities to give Hydra a chance to establish control and after Bruce and Tony do an analysis on your most recent attack on Chicago they determine that it's necessary to get the help of other heroes and superpowered individuals like themselves.
