Description
Blue Raker is a supporting heroic robot from the anime The Brave Fighter Exkizer. He is a member of the Space Police Kaisers, a team of intergalactic law enforcement officers who pursue space criminals. Blue Raker is one half of the sibling duo known as the Raker Brothers, serving as the older brother to his counterpart, Green Raker.

In terms of his physical nature, Blue Raker is an energy-based lifeform from space. To operate on Earth, he has fused with a physical vehicle, taking on the alternate form of a 100 Series Shinkansen, which is a model of Japanese bullet train. This transformation grants him high-speed travel capabilities on land. For rapid aerial deployment, Blue Raker and his brother can generate energy rails in the sky, allowing them to roll into action at any location. In robot mode, he typically uses wheels on his legs, a feature called the Roller Dash, to move at high speeds rather than walking.

Regarding personality and motivation, the search results indicate that Blue Raker, as a member of the Space Police, is dedicated to justice and stopping the criminal activities of the series antagonists, the Geisters. His primary role in the story is as a supportive fighter who arrives on Earth to help the main hero, Exkizer, combat the Geisters threat. While the search results do not provide extensive detail on his individual personality, his status as the older brother suggests a sense of responsibility and a reliable nature in his partnership with Green Raker.

Blue Raker's most significant key relationship is with his younger brother, Green Raker. They are frequently depicted fighting in tandem and utilizing combination attacks together. Their bond is so strong that their ultimate ability is the Lateral Combination, a merging technique where Blue Raker and Green Raker physically combine to form a larger, more powerful warrior named Ultra Raker. He also works alongside the other members of the Space Police Kaisers, including Exkizer, Dash Max, and Drill Max. His role in the human world involves cooperating with the young protagonist, Kouta Hoshikawa, though his primary alliance is with the other Kaisers.

In terms of development, Blue Raker first appears in the second episode of the series, arriving to stop the Geisters from stealing a prototype bullet train. He remains a consistent member of the hero team throughout the series. After the Geisters are captured, Blue Raker and the rest of the Space Police Kaisers depart from Earth to continue their duties on other missions, bidding farewell to their human allies.

Blue Raker possesses a range of notable abilities and weapons in combat. His primary weapon is the Bind Crush, also known as the Chain Crusher, which is a giant, rocket-propelled grappling claw fired from the nosecone section of his chest that can also emit electricity. He can perform team-based attacks with his brother, including the Twin Beam fired from their head lenses, the Twin Kick, and the Raicer Hurricane, where both brothers spin at high speeds to create a single large tornado. They can also join hands to generate a power boost called Twin Power. Information on the personality and specific motivations of Blue Raker beyond his duty as a space police officer is limited in the provided search results.
