Ernst is both a surname and a given name, the German, Dutch, and Scandinavian form of Ernest. Notable people with the name include:
Prince Ernst Alfons Franz Ignaz Joseph Maria Anton von Hohenberg (17 May 1904 – 5 March 1954) was the younger son of Archduke Franz Ferdinand of Austria and his morganatic wife Sophie, Duchess of Hohenberg, who were assassinated at Sarajevo in 1914.
Ernst was born at his parents' estate at Konopiště in Bohemia. Following his parents' assassination, which precipitated World War I, Ernst and his siblings, Sophie and Maximilian were taken in by their uncle, Prince Jaroslav von Thun und Hohenstein.
In late 1918, their properties in Czechoslovakia, including Konopiště and Chlumec nad Cidlinou, were confiscated. The children moved to Vienna and Schloß Artstetten. In 1938, following the Anschluss the family were arrested, Ernst previously having spoken at pro-monarchist meetings and having publicly opposed Anschluss, was sent to Dachau concentration camp with his brother. They were freed in 1945 when World War II ended. Their Austrian properties were confiscated in 1939 but were returned in 1945.

Within the context of the stories, Ea is an action figure sized Celestial Machine Man carries and treats as an "imaginary friend". The story featuring Ea is unclear if he is actually a Celestial or a figment of Machine Man's mind as Ea disappears when the android resolves his mental issues.
Earth Sentry (John Foster) was created by Tom DeFalco and Ron Frenz, and first appeared in A-Next #2 (1999).
When John and his father Bill were investigating a UFO crash site, they discovered a Kree space probe. Upon nearing the ship, the automated defenses activated, and a robotic sentry was released. Bill activated a distress signal which was picked up by Mainframe and the rest of A-Next.
When the heroes arrived, the sentry robot attacked them. Thunderstrike's sonic blasts and J2's superstrength were not slowing the attacker. Stinger was able to blind the robot's optic sensors with sting darts, providing an opening for John to enter the ship and try to turn off the robotic sentry. When John made contact with the ship's console, a strange energy surge ripped through the ship's computers and struck John. The energy wave reconfigured John's DNA, making him genetically similar to a Kree warrior.
