(Civil War: Front Line#4 (fb) - BTS / Official Handbook of the Marvel Universe A to Z hardcover#14: Anti-Registration Underground (fb) - BTS) - Following the Stamford disaster, where hundreds had perished during a battle between New Warriors and four Raft escapees, Iron Man (Tony Stark), Mr. Fantastic (Reed Richards) and others worked with US officials to develop the Superhuman Registration Act (SHRA), outlawing any crimefighting activities by unregistered super heroes. 

    Vigilante Typeface, although his identity was already known, resolved to fight a perceived assault on freedom, and he organized an Anti-Registration Underground, beginning with ex-government operative Battlestar and anti-terrorist Solo, to support super heroes who continued fighting crime without SHRA approval. Their ranks were soon supplemented by mystic-armored Freeware; bodysuit-enhanced Green Guardswoman; Masked Rose, leader of super-team T,J,A.W. (Truth, Justice, and the American Way), empowered by accidental mutant blood exposure; exoskeleton-empowered Network; and cyborg Skybolt. Via a covert interview with Alternative reporter Sally Floyd, ARU members publicized their perspective, and several other anti-registration heroes joined, including Brain Spasm.

(Civil War: Front Line#4 - BTS) - Brain Spasm was likely present with the ARU when S.H.I.E.L.D. raided the ARU's safehouse and arrested most of its members.

(Civil War: Front Line#6/2 - BTS) - Brain Spasm was arrested and imprisoned in Prison 42.

(Civil War: Front Line#6/2)  - Brain Spasm was seen lying on the floor of his cell in Prison 42.

(Civil War#7 - BTS / Amazing Spider-Man I#538 - BTS / Civil War: Front Line#10-11 - BTS) - The Secret Avengers penetrated Prison 42, freeing many prisoners. When the combined anti-registration forces were confronted by Iron Man's pro-registration forces, Secret Avenger Cloak (Tyrone Johnson) teleported both groups to Manhattan. Freed ARU prisoners took part in the battle between the pro and anti-registration heroes, spanning from the Negative Zone prison to the streets of New York. In the ensuing battle, which caused severe damage, the Thunderbolts' Venom (Mac Gargan) apparently killed Typeface. Other fatalities may also have occurred. Following Captain America's surrender to forestall further civilian risk, Battlestar and possibly others avoided recapture.

    The government offered amnesty in return for registration. Although Gladiatrix rejected the offer, Network registered under the 50 States Initiative, while Solo also registered but pursued independent interests. Presumably additional ARU members followed Gladiatrix's example, others followed Network's or Solo's, and still more remained at large.

    Codename, real name, and nature provided by Ronald Byrd

   During the production of the Civil War: Battle Damage Report (2007) writer Paul Jenkins provided Ronald with authorization to provide identities, real names for the various background Anti-Registration Underground characters, and to flesh them out as much as he wanted. Ronald provided identities and real names for the Anti-Registration Underground entry in Official Handbook of the Marvel Universe A to Z hardcover#14 (2010). There wasn't room to provide much more than that in that entry. However, Ronald had backgrounds and histories in mind for these characters when he provided their names.
    Sadly, Ronald passed away before he could finish this profile, but I completed it and am publishing it in his honor/tribute.
    While the information is unofficial until it sees print, here is the full story behind Brain Spasm:

REAL NAME: Dennis Hoxie
ALIASES: None
IDENTITY: Known to US authorities
OCCUPATION: Mental institution resident; former adventurer
CITIZENSHIP: Presumably USA
PLACE OF BIRTH: Unrevealed
KNOWN RELATIVES: None known
GROUP AFFILIATION: None known
EDUCATION: Possible high school graduate
SHRA CLASSIFICATION: Magic-Based Mutate
FIRST APPEARANCE: (Behind-The-Scenes) Civil War #4 (2006); (seen) Civil War: Front Line #6 (2006); (identified) Official Handbook of the Marvel Universe A to Z hardcover#14 (2010)

HISTORY: At a party during his junior year of high school, Dennis Hoxie, while intoxicated, accepted a dare to stand before a full-length mirror and recite an alleged mystic chant which would supposedly summon an occult being. The chant succeeded, but even as the being began materializing, unidentified semi-sentient extradimensional entities (possibly related to the Limbic Infundibula of Limbo) that used mirrors as portals into other dimensions moved to enter the Earth dimension through the mirror in question. The being's occult force startled the entities, who instinctively unleashed defensive energies through the mirror and into the Earth dimension, dispersing the occult being and striking Hoxie, granting him superhuman mental abilities.

Dennis declined to register with the Superhuman Registration Act out of concern that the government would institutionalize him; while in prison, he heard some of the guards discussing Spider-Man's revelation of his secret identity as Peter Parker, but by the time he was released, Doctor Strange had already removed that knowledge from most of the rest of the world, but Brain Spasm still remembered it and, now convinced he was indeed going insane, had himself committed to South Brooklyn Psychiatric Facility, where he remains as of this writing.

HEIGHT: Unrevealed           WEIGHT: Unrevealed
EYES: Unrevealed               HAIR: Strawberry blond

ABILITIES/ACCESSORIES: Dennis receives "messages" from other people's thoughts and from forms of communication (cell phones, internet, et cetera) but cannot transmit his own thoughts to anyone. He is immune to telepathic control, and he is immune to memory alteration (although he is unaware of this and thus retains memory of events that were wiped from most of humanity's collective mind (identity revelation of Captain America (Rogers), for instance). He remembers every reality shift of his lifetime (including the Age Undreamed Of, the reality-alteration(s) associated with the events of the Infinity Gauntlet, Morgan Conquest, House of M), although he himself does not realize this and thus believes he is gradually going insane.
