Wonder-Blue is one of the main heroes in the Wii-U game, The Wonderful 101, and a member of the CENTINELS Planetary Secret Service. His real name is Eliot Hooker, and he is an LAPD Detective outside of being a Superhero. He attacks with his Valiantium Blade.
Wonder-Blue is a Wonderful One whose cover occupation is as a detective for the Los Angeles Police Department. Though young, he has gained experience and success in a variety of missions: taking down warring mafia families, counter-terrorism, and even taking part in military operations. A master of the sword, he is one of the Wonderful 100's most powerful combat agents. He takes issue with Red being appointed the leader of the current operation, despite his novice status.
Regardless of his constant banter, his skills as a swordsman are second to none. This has earned him the nickname of “The Supersonic Blade”. It goes without saying that this name is derived from his Valiantium Blade, which he puts to devastating use in his Unite Sword attacks.
In his civilian form, Eliot is a young man who has light blue hair that is tied into a ponytail. His bangs are swept to the left side of his face; one of them is streaked with a dark hue of indigo. He dons a light blue shirt, black pants and shoes.
As Wonder-Blue, he sports a blue CENTINELS suit along with a slightly light shaded periwnkle-colored jacket. Likewise, Eliot wears black shoes, but with white accents and laces and the two edges folded. Like every Wonderful One, Blue wears a standard Wonder Mask and a Shirogane Drive, embedded on his torso.
Believing himself to be a cool and perfect role model, Wonder-Blue is shown to be hot-blooded, reckless, and absolutely arrogant, serving as the opposite of Wonder-Red. Blue is the most troublesome of the team, but is reliable enough to lead the team in success. His pride is also his weakness; Wonder-Blue doesn't take kindly to being led by Wonder-Red, a comparatively new member of the Wonderful Ones, and in the first battle against Vijounne (his brother's murderer), he flies at her head-on, but gets batted aside effortlessly, allowing her to get away.
However, he does have a sense of right and wrong. During the course of the story, Wonder-Blue goes from being a somewhat loose cannon who is out for vengeance on the people who killed his brother to being more willing to work with the team and actually caring about their goals. Likewise, when he hears of Red's backstory, Wonder-Blue realizes he's not the only person who has been hurt by the GEATHJERK and stops trying to pick fights with people.
