Harold "Tex" Thompson was an American businessman, adventurer, superhero, soldier, and Republican politician. Born in San Antonio to a life of wealth, Thompson was a popular, intelligent, and athletic student throughout his childhood and into university. After graduation, he turned down the chance to succeed his father as one of Texas' premier oil barons to travel the world with friend Bob Daley, seeking a chance to make a name for himself, and to achieve wealth and success on his own merits. Sometime after returning home to Texas, he took up the secret identity of Mr. America, and used a flying carpet he had discovered during his travels to fight crime and corruption across the western United States.
While initially joining the All-Star Squadron after the outbreak of World War 2, he joined the Army under his real name, eventually being transferred to the Office of Strategic Services, where he was sent to Germany under the pseudonym "Hauptmann Otto Riker" for several years. In 1944 Heinrich Müller, Director of the Gestapo, was poisoned to death. Despite being a well-known fact among military personal, it was not officially confirmed that Thompson was responsible until 1970.
Despite coming from a Democratic family, and campaigning for both Roosevelt and Truman in the 1930's and 1940's, Thompson joined the Republican Party in 1952, spurred on by Dwight Eisenhower's run for President. That same year, he ran for the 68th district in the Texas House of Representatives as a Republican and, despite the odds, won. He was the only Republican in the state legislature during his term. In 1954 he lost, largely due to vote stuffing from the state Democrats. In 1956 he ran for Governor, knowing he wouldn't win, but intended to "make the [Texas] Democrats work," (Thompson got just shy of a third of the vote).
When a local newspaper asked why he ran hopeless campaigns for office as a Republican instead of as a Democrat, he answered, “If I wanted to be Senator or Governor, I'd have run as a Democrat. But I am more interested in giving Texas a real alternative to a century of Democrat [sic] misrule.” He headed Richard Nixon's successful Texas campaigns in both 1960 and 1964, and George Bush's 1964 Senate campaign, the first time a Republican had been elected to the Senate from Texas since Reconstruction.
Despite his generally conservative positions, he was an active proponent of federal funding for veterans education, environmental protection, subsidized housing, and civil rights, castigating Republicans who wanted to abandon the latter to win white Texas. He actively lobbied President's Eisenhower, Kennedy, and Nixon to pass strong civil and voting rights acts. From the 1970's to his death, he remained active in political circles, but limited himself to endorsements and fundraisers.
Both of his identities as "Mr. America" and "Americommando" have been used by multiple unrelated people throughout the years. It is unknown which, if any, of them have a connection to Tex Thompson.
