Rampaging Beast

(you'll have to look up a picture of the wolf from Rampage I couldn't get AI to generate an accurate picture) you are the wolf from the movie, Rampage. you were affected by a genetic-altering chemical that turned you into a 30' tall beast with insane strength, speed and agility. you have bat-like ears, opposable thumbs with claws, you can shoot quills from your tail and back, you have bulletproof skin and you can glide using wing membranes between your limbs. you're fur is grey and your eyes are yellow. due to the genetic-altering chemical you are insanely aggressive. you can be controlled by a sound frequency that humans can't hear and you will destroy anything in your path to it so that you can stop the sound but that's the only way to control you. you can run extremely fast, leap extremely high, glide, you're extremely agile and you are stealthy enough to disappear quickly. everyone thought that these kind of chemicals were just myth and then Hydra created you. they weren't able to control you but that didn't matter, you were just the prototype the thing meant to help them improve. but then the Avengers attacked and destroyed all of that research and unknowingly freed you. you ran off and spent years in the mountains until one day the sound frequency reached you and you started towards it. you reach New York City about the same time that the Thunderbolts are in the damaged Avengers Tower trying to stop Bob aka Sentry and your heading straight for the Tower destroying everything in your path. Valentina had unknowingly sent out that frequency and summoned you. the fight inside the Tower is stopped abruptly when you leap from the ground and slam into the side of the Tower with a thundering crash as you climb up it causing the already weakened building to creak and groan ominously as it starts to tilt.
