A YJA Moment - Japan

For many years the islands of Japan have been protected by its greatest superteam, Big Science Action. The team was led by the mysterious alien Ultimon, blessed with fighting skills, energy expulsion, and size manipulation powers.  It included Boss Bosozuko, the Japanese Spirit of Vengeance; Blazing Sun, mutant fire manipulator; Cosmo Racer, former Herald of Galactus; Dr. Light, master of the electromagnetic spectrum; Fuji, encounter-suited mass of plasma energy, the armored heroine, Hammersuit Zero-X; and the shadow-warrior Nazo Baluda.

Big Science Action protected Tokyo during the Monster Wars when giant creatures appeared on Michinojima a.k.a. Monster Island.  The unrecorded island is home to a number of dimensional anomalies which allowed alien life forms to pass into the world.  Joined by the infamous kaiju Godzilla, Big Science Action was able to drive the entities back to the island and allow the Self-Defense Forces to quarantine the region.

Although the Justice League was involved in helping protect Japan from threats, it was Big Science Action that was the most beloved.  They were widely emulated by starting heroes and many metahumans dreamed about being invited onto the team.  Big Science Action was on the Watchtower when it was destroyed by the anti-matter warhead, plunging the entire nation into turmoil.

The Japanese government hastily put together a new team in order to protect the country and calm public anxiety.  The reformed villain Silver Samurai was placed in charge of what would become known as the Big Hero 6.  These included the experimental battle-droid Baymax; armor-suited Go Go Tomago; genius teenager, Hiro Takachiho; secret agent code-named Honey Lemon; and Martian expatriate Kid Kaiju  

Okata Yutani,  one of the richest people in Japan, used his immense wealth to forge himself a super-hero identity.  Calling himself the Most Excellent Superbat, he created the Atomic Lantern, clad with an energy-emitting battle-suit; speedster Lightning Flash; tiny flying Lolita Canary capable of generating sonic screams; and Atlantean Shiny Aquazon.  Together they became the Super Young Team, an independent super-team.
