Huck (ハック Hakku) is the robotic companion of Captain Ultra and the only sidekick who remains by Captain's side throughout all of his missions across the series.
Huck went through lots of hardship in the series. He was possessed, broken into pieces and shut down at different points. But, he is always able to help Captain and the crew of the Silver Star defeat whatever foe comes their way, be it the Alien Vandel or a completely different enemy.
