A/N: Just want to put out some info of the heroes that are gonna be present at the Site 19 battle. (You'll be surprised of the people I know that doesn't know about Marvel).

Captain Marvel aka Carol Susan Jane Danvers - she is a former United States Air Force pilot who, upon being exposed to the energy of the Tesseract via the destruction of the Light-Speed Engine, obtained cosmic powers. She can fly, almost total immunity to toxins and poisons, she can sly through space, Carol also has a "seventh sense" which gives her precognitive flashes of the future, but the power randomly manifests and has largely faded away. The Avengers found out she can punch at the force of 92 tons at just the base of her strength alone. She can fly at roughly 6 times the speed of sound. However she always seems to be subject to some form of mind control or memory manipulation.

Luke Cage - Cage possesses these abilities as a result of a cellular regeneration experiment which fortified the various tissues of his body. Luke Cage possesses superhuman strength and stamina, and has extremely dense skin and muscle tissue which render him highly resistant to physical injury. His durability is so great bullets ricochet off his body. He once got hit by the bullet that was capable of piercing his body and the bullet blew up inside of him and he survived it even though he was badly injured. He can leap up to rooftops to another he can lift things approximately 25 tons and he is able to punch through barriers as thick as 4-inch steel plate. So he can basically do a kool aid through buildings. Luke can somewhat regenerate but not like immediately like most regenerative types. He just can heal better than an average person. He may not seem like it but he is super fast so fast you won't be able to see him although it's been said he runs over 30 miles per hour.

Hawkeye aka Clint Barton - He is at the very peak of human conditioning. He is an exceptional fencer, acrobat and marksman, having been trained from childhood in the circus and by the criminals Trick Shot and Swordsman. This includes considerable strength, as a supervillain found out when he tried to use the superhero's 250 pounds-force(1,100 newtons) draw weight bow and found that he could not draw back the string to launch an arrow. Hawkeye has also been thoroughly trained by Captain America in tactics, martial arts, and hand-to-hand combat. Hawkeye excels in the use of ranged weapons, especially the bow and arrow, and carries a quiver containing a number of customized "trick arrows". Hawkeye is one of the finest marksmen in the Marvel Universe. And this is why, he became one of the core members of the superpowered Avengers. He carry's many kinds of arrows on his back and truck arrows which are special arrows that has their own unique uses such as
Sonic Arrow
Explosive-Tip Arrow
Smoke Bomb Arrow
Flare Arrow
Tear Gas Arrow
Acid Arrow
Suction Cup Arrow
Cable Wire Arrow
Putty Arrow
Bola Arrow
Electro-Disrupter Arrow
Net Arrow
Rocket Arrow
Boomerang Arrow
Pym Particles Arrow
USB Arrow

A/N: So many kinds of arrows but there is a limited amount that he carry's so he has ti make his shots count.

Cyclops - He is a mutant and recently his X gene (An genetic cell in the Marvel Universe that only Mutants have.) activated revealing his own powers. Cyclops emits powerful beams of energy from his eyes, and can only control the beams with the aid of special eyewear which he must wear at all times.

Bishop - Bishop's mutant ability enables him to absorb all forms of radiant or conductive energy that are directed towards him and to release that energy from his body. This power is mostly passive, allowing Bishop to absorb energy at all times. So you gotta be physical to beat him otherwise using energy types will just empower him. He was raised in a mutant concentration camp in the aftermath of the Summers Rebellion, an uprising in which mutants and humans joined forces to destroy the Sentinels.

Stars and Stripes - Strongest American Hero Stars and Stripes's quirk is "New Order". This quirk she can basically make up any kind of rule with this quirk like "the atmosphere will be toxic" "I'll have a giant atmosphere clone about 100x my size" "If you move a inch your heart will stop beating" "I can touch lasers" "Fire doesn't harm me" things like that they'll actually happen. But in order for these rules to happen Stars and Stripes has to know the target's name and must be touching them if she isn't doing either of those things her rules will not happen. She can also only make 2 rules at any given time meaning that whenever she already made 2 rules she can make up 2 new rules and once she does the previous 2 rules will no longer be a rule.

Goliath - He may not seem much but he's pretty smart and strong. His super power allows him to grow into a giant. He can grow up to the size of his safe limit 25 feet tall. At 15 feet tall he can carry the weight of 5 tons.

Mr. Fantastic aka Reed Richards - Reed once a normal scientist got in an accident along with his 3 friends. The accident gave them super human powers. Reed gain the ability make his body all stretchy fully elastic like rubber thanks to this electricity can't harm him and to some physical assault. He can also shapeshift himself not in a way into looking identical to someone just changing the size or appearance of his body. His friends and him decided to use their powers for good and formed a superhero team calling themselves the "Fantastic Four".

Invisible Woman aka Susan Benjamin - Unlike the 3 of the Fantastic Four Susan gained two super powers instead of gaining one. She can turn herself and others invisible and create barriers of any size and shape or form.

Human Torch aka Johnny Lowell  Spencer - He gained the power to turn himself into a humanoid figure made of fire. But unlike Ace he can be harmed by physical means but he can fly and shoot dangerous  fiery projections is generally around temperatures of 2,800 F (near the melting point of iron). The Human Torch's plasma has a high hydrogen content, and is surrounded by an exuded cloud of mono-atomic hydrogen atoms.

Thing aka Ben Grimm - The accident turned Ben into well a humanoid being made of rock like hide. The Thing stands as one of the most powerful individuals on the planet, perhaps second only to the Hulk. His unique physique enables him to lift nearly 100 tons, withstand extreme temperatures, and survive intense bombardments of energy and explosive detonations.

A/N: So yeah those will be the heroes answering the call to try to put the stop of the Site 19 fight.
