Pictures of Ultraman Jack Monsters -

The show features a new Ultraman named "New Ultraman" (新ウルトラマン, Shin Urutoraman), or "Kaettekita Ultraman" (帰ってきたウルトラマン). In 1984, he was renamed "Ultraman Jack" (ウルトラマンジャック, Urutoraman Jakku) due to licensing issues. Tsuburaya and Bandai (which had just bought the Ultraman toy license in Japan) held a contest for children to pick a new name for this Ultraman. Although he is called "Ultraman Jack" for licensing in and out of Japan, he is still sometimes referred to as "New Ultraman"/"Kaettekita Ultraman", by some fans (and also in some official sources). This change was done due to a last-minute decision as the original plan for this series was for the original Ultraman to return to Earth to continue fighting against aliens and monsters.
