Yuusaku Hayakawa

"MegaSilver!"

- Yuusaku

Yuusaku Hayakawa is MegaSilver of the Megarangers. He is a 25-year-old leader of the Space Mega Project for I.N.E.T.

Megaranger
Although a major player at I.N.E.T., Yuusaku desired to fight alongside the Megaranger against the Nejireija, even against the wishes of higher authorities such as Professor Kubota. When he discovered a prototype silver version of the Megaranger suits used for the five Megaranger both for the video game and combat, Yuusaku takes the suit, and the Keitizer tied to it, and begins to use it to assist the Moroboshi High students. Though initially wanting to use it on his own, he becomes punished by Kubota for his reckless action until the I.N.E.T. leader realizes the importance of having another member, allowing for him to fight along side the Megaranger despite his other duties.

While desiring to be a Megaranger, Yuusaku's main concentration is the "Space Mega Project", which is revealed to be the Voyager Machines and the Mega Voyager mecha utilized to increase their battle capacity as their previous mech trump card became overwhelmed, most notably during the battle with Mad Guirail.

At first Yuusaku could only stay in his MegaSilver suit for 2.5 minutes due to a flaw in the prototype silver suit. Regardless of this flaw, he decides to hold off on any serious combat with the suit and manage any threat on his own before bringing it out, seeing all threats as easily defeatable within his 2.5 minute limit. However, after the completion of the Mega Voyager, Yuusaku turned his studies to fixing the flaw in the MegaSilver prototype using his knowledge and expertise to finally fix the suit and allow for him to use it without the 2.5 minute time restriction. The main reason for finally fixing the suit for Yuusaku was the fully finished suit would allow him to control the Mega Winger, his own personal mech. However, the management of I.N.E.T. nearly shut down Yuusaku believing he was going beyond the scope of his duties to help the Megaranger, who were supposed to be a team of five from the beginning while the MegaSilver suit was never to be used beyond initial testing. But when Hayakawa nearly sacrifices himself to save other I.N.E.T. officials and the Megaranger, Kubota vouches for him and the corporation finally permits him to continue with his MegaSilver duties.-

During the battle with the twisted Neziranger, Yuusaku assisted in a rather peculiar way. During several schemes Shun attempted to enact to prevent the evil team from fighting their colored opponent, he created a team with five MegaBlue using his illusion abilities. Further, he and Yuusaku developed a NeziSilver suit similar to the suits devised by Dr. Hinelar, with it's own twisted Silver Blazer weapon. Yuusaku as "NeziSilver" further confused the Neziranger by attacking all of the MegaBlue as well as themselves without discern, perfectly portraying the role schemed up.

In the climax of the series, Yuusaku was instrumental in Dr. Hinelar's downfall. During the invasion of Hinelar City, he used Hinelar's own machines to permanently seal away the Neziranger within data cards while setting the main base to blow, destroying the doctor's plans. Later, Yuusaku was the main force fighting to protect the I.N.E.T. moonbase when Yugande invades in search of the Megaranger. The Delta Mega is destroyed and his own Mega Winger is heavily damaged in the battle, forcing him to clean up and maintain the base as well as launch the Voyager Machines manually for the last time during the final battle with the Grand Nejiros. After Hinelar's final fall, he attended the main five Megaranger's graduation ceremony.-

Gokaiger
Years later, Yuusaku fought alongside not only his own team, but every single Sentai ranger in existence, against the Empire of Zangyack when it attacked the Earth in the Great Legend War. After fighting against hundreds of Gormin and their Zgormin commanders. AkaRenger noticed the fleet moving towards them, he gathered all the Rangers together and gave them the order to sacrifice their powers to wipe out the first invasion's armada. Being a sixth ranger, his ranger key was acquired by the Zangyack's ally Basco ta Jolokia. But it was taken by the Gokaigers in episode 16, then was first used by Luka Millfy in episodes 17 and 18 via the ranger keys.

After Zangyack's final defeat by the Gokaigers, Captain Marvelous returned all the Ranger Keys to their original heroes. Yuusaku and his team have their powers back.

Ranger Key
The MegaSilver Ranger Key (メガシルバーレンジャーキー) is Yuusaku Hayakawa's personal Ranger Key and what became of his powers after he along with the rest of the 34 Super Sentai sacrificed their powers to end the Great Legend War.

This key, along with the other fourteen sixth ranger keys and the ten extra hero keys, were initally acquired by Basco ta Jolokia and later used by the Gokaigers. Like all of his Ranger Keys, Basco used his trumpet, the Rapparatta, to turn the MegaSilver key into a puppet to do his bidding. The copy MegaSilver was one of the remaining ten sixth rangers after the Gokaigers defeated the first five, with Basco using these ten to ambush the Gokaigers and take all of them hostage bar Marvelous. When Marvelous rescued them, they defeated all 10 puppets and claimed the Ranger Keys.

While in the possession of the Gokaigers, the MegaSilver Ranger Key was mainly used by Gai Ikari (Gokai Silver), who used it to fight as MegaSilver. It was also used by Luka Millfy on two occasions.
 * Luka became MegaSilver when the Gokaigers used the powers of the sixth heroes while fighting Action Commander Almadon.
 * Luka became MegaSilver as part of an all-silver Gokai Change in the Gokaigers' fight with Action Commander Osogain.
 * When the Gokaigers became the Megarangers while protecting Jealousto from Gormin fighting in the name of propaganda.
 * When the Gokaigers became the Megarangers to reveal which Gokai Silver was the real Gai. Gai became MegaSilver, while Action Commander Vannain was exposed as he remained Gokai Silver.
 * When the Gokaigers became the Megarangers in their fight against Basco and Sally, thwarting their attempt to gain the greater power of the Megarangers.

After Zangyack were finally defeated, the Gokaigers gave the Ranger Keys back to their rightful owners. It is presumed that Yuusaku received his key and became MegaSilver once more.
