Legion Academy
Academy for the training of potential Legionnaires in the 30th Century DC Universe. Located on the shores of Montauk, New York.
Origin

The Legion Academy is a school based in the 30th century Earth, located off the coast of New York on Montauk Island. The campus houses a computer source library, various training gyms, student dorms, classrooms, an auditorium, med-lab, and a student activity center. The Academy has become the epitome of training for those with dreams of one day becoming a member of the Legion of Super-Heroes. The Academy teachers practice the belief that a solid institution can help mold its students as possible future heroes on they're own right, not only as hopeful members of the Legion of Superheroes.
Creation
The Legion Academy is a training school for members of the Legion of Super-heroes. It was created by Jim Shooter and Curt Swan, and has been re-used and revisited by subsequent writers many evolving iterations of the Legion published over the decades. The first appearance of the Legion Academy was in the Legion of Super-Heroes.
History
Silver Age; Original Continuity

Situated off the shores of Montauk Island within a metallic tower several stories high. At its base it expands onto its ground and rising back up as another smaller adjacent tower. Since it is located right on the southern tip of Montauk Island it also acts as type of beacon or "light house" with the tallest tower having a glass lit top. Isolated from the rest of the small population which also resides on the Island it is a perfect location for the school.
The Legion Academy history of training a dynamic and wide student body on how to perfect the various individual powers. Many form all around the galaxies would apply, all with hopes that as students meant exposure to the Legion of Super-Heroes when they would need to expand the roster.
The Academy training has also groomed several former students for eventual Legion membership. Chemical King, Dawnstar, Karate Kid II, Magnetic Kid, Tellus, Comet Queen and Timber Wolf are all graduates of the Academy. Training there may be deficient to some degree, however, as Chemical King, Karate Kid II and Magnetic Kid have all died in the line of battle. Although as two of those were selfless sacrifices made to save others, they clearly teach heroism quite well.
Bouncing Boy and Duo Damsel really found their niche when they became instructors at the Legion Academy, demonstrating to new heroes how teamwork, quick-thinking, and courage could make great heroes out of the weakest powers. At times they have had to keep truant students away from the areas oceanfront parkland, casinos, and clubs.
5-Year Gap; Five years Later

When increasing hostility from Earthgov and a lack of funding led to the closure of the Legion Academy, Bouncing Boy and Duo Damsel were tapped by one of the United Planets greatest generals, King Jonn of Pasnic, to become Co-Instructor Generals of the newly-opened United Planets Militia Academy on Xolnar. Along with many of their former Legion Academy students, they began training meta-powered beings to become soldiers and special operatives (militia, ground forces, as opposed to operating within the UP Starfleet where there powers would be wasted), helping to stiffen the UP’s resistance to invasion by the Khund Empire.
Retroboot; New Earth
The event of Infinite Crisis restored the original continuity before the Five Years Later and this would harken the return of the Legion Academy. Still housing its campus on Montauk , new York the Academy campus would be a major site for the students who were graduating from attending the school and becoming alumni. Several members of the student body such as Comet Queen, Dragonfire, Glorith, and Chemical Kid would join the Legion.
