Idaten Jump is an anime that was broadcast in Japan from October 1, 2005 to September 9, 2006. It lasted 52 episodes in its Japanese run, however only 26 episodes were dubbed into English.
These episodes were released by Hasbro and aired on Cartoon Network in America, YTV in Canada and Nicklodeon in India, in hopes of creating a new popular toyetic anime franchise (unfortunately, the marketing failed as Cartoon Network only aired the show in a 6 am timeslot). Both networks completed the full 26-episode run, however no DVDs were ever released of the show in English. Japanese DVDs are exceedingly rare, and due to the show's low popularity in North America there are slim to none online recordings of the show in English or Japanese.
However, later episodes of the show have been discovered thanks to a fandom in India, where the show regularly airs on the channel Nickelodeon Sonic. However, these episodes are dubbed in Hindi, Tamil and Telugu.
There is also an English dub by Animax, but they are not online.
Only the first episode of the English dub has appeared online, though there is photographic evidence some episodes were available on the Hasbro site despite the show's failure in late 2009.
