An alien conqueror from the star system Antares.
Either Kroseth IV or an earlier incarnation, battled Honor Guard in 1959.
In December of 2002, after spending almost a year disguised as a ranch home owned by Rosemary Lucey, residing in the somewhat ritzy neighborhood of Goldwater Heights, Kroseth was discovered and captured by Honor Guard. Early that year, Honor Guard had used the same Repli-Matrix material to rebuild the small house shortly after it had been destroyed in a fight involving Samaritan and the Glowworm.
Circa 2013, using the moniker of Kroseth the Invader, he once again fought Honor Guard. This time in Montana.
Kroseth has the ability to mentally control other beings.
