Captain Dynamo, a superhero who first appeared in
Noble Causes: Extended Family #2 (June 2004) was depicted as a womanizing philanderer, and in
Dynamo 5 #1 (January 2007), following Captain Dynamo's assassination, his widow,
Maddie Warner, a former government agent posing as now-retired investigative reporter, discovers from his personal effects that he had been unfaithful to her countless times. Despite her devastation at this discovery, Warner realizes that without a full-time protector, Tower City will be vulnerable to Captain Dynamo’s legion of
supervillain enemies. She uses her skills to track down five people who could be Dynamo’s illegitimate children. Spencer Bridges is the third person Warner contacts to be on the team. He agrees to join the team only because Maddie is paying him. Gathering all five of the children together, Warner exposes them to the same unidentified radiation that gave Captain Dynamo his powers forty years earlier, unlocking their powers. Spencer, who manifests his father's
shapeshifting ability, takes on the codename
Myriad, and works to protect Tower City with his newly discovered brothers and sisters. At some point Spencer took on Dr. Bridges' last name, though when he did so is unknown. The origin of his first name, and the point in his life at which he adopted it has also not been specified. His siblings feel betrayed by his having kept his true nature a secret. Spencer sees this as hypocrisy, as all of his siblings have lied to their families about who their real father was, about their lives as superheroes, and allowed a murderer named Lionel Barstow to go free in order to free Neil Lewis, the father of Spencer's sister,
Slingshot, who was being held hostage by Barstow's former employers. This argument does not convince Spencer's siblings, and as a result of both this revelation, Warner's condition, the flooding of the Aquarium, and the need to return to their civilian lives, the team seems to fall apart. Despite this, Myriad decides to continue fighting crime in Tower City himself. He moves to a Tower City hotel, and uses his shapeshifting abilities to pose as a female masked vigilante named
Vigil, relying on his natural speed, martial arts and acrobatic abilities to fight crime. When he encounters Scrap, the only other team member who decided to continue protecting Tower City, Scrap, not knowing that Vigil is her brother, decides to team up with Vigil, who poses as a native of Tower City. The two later recruit three other superheroes, Quake, and the mother-daughter team the Firebirds, into a new Dynamo 5 team. The new team suffers badly against Widowmaker, who assembles a team of supervillain mercenaries to attack them, and during this battle, Vigil is revealed to be Myriad. The team is joined by Slingshot,
Scatterbrain, and
Visionary, who manage to defeat their enemies. Although Quake and the elder Firebird are seriously injured, the Dynamo 5 siblings are reunited as a team. In issues 22 and 23, it was revealed that in order compensate for the lack of offensive superhuman powers that lent themselves to combat situations that his siblings had, Spencer had been taking Flex, a street drug derived from the serum that turns humans into Whiptail, a monstrous, bipedal lizard. After he was discovered, he led his siblings and F.L.A.G. agent Augie Ford to his dealers, but agreed to stop taking the drug. He subsequently discovered, however, that his elevated strength, speed and endurance remained, which
Doc Noble speculated occurred because it bonded to his extraterrestrial
DNA. In issues 24 and 25 of the series, the team was attacked by their other half-sibling, the
supervillain Synergy, who used a weapon to erase the team's abilities and capture them. The team freed themselves, and used the weapon to restore their powers, but they manifested different abilities than the ones they previously had. Spencer found that he and his brother
Gage, had switched their powers. Now possessing
telepathy, Spencer took the new codename Wraith. In
Dynamo 5: Sins of the Father #3 (August 2010), Spencer learns, while battling another extraterrestrial who recognizes his race, that his people are called the Khandrians. During this encounter, the telepathic Spencer sees in his opponent's mind an image of a humanoid being held captive by Khandrians who were apparently experimenting on him. It is also during this battle that Dr. Bridges sees Spencer on television. ==Personality==
