From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Kyokugen Batoru!! San Daichō Saiya-jin Supesharu (極限 バトル 三 大 超 サイヤ人 スペシャル, Kyokugen Batoru!! San Daichō Saiya-jin Supesharu) is a very rare TV Special that is part of the Dragon Ball Z series of anime. The TV Special is believed to have been aired on Fuji Television sometime after July 11, 1992 between DBZ Episode 148 and DBZ Episode 160.
The setting of this film is identical to that of Dragon Ball Z: Super Android 13! except that Son Goku and Son Gohan appear in the streets wearing sharp tuxedos. In fact, it is noted by Goku himself that the events taking place in this TV Special are after that of said film. In this film, the two Saiyans discuss the first three movies of Dragon Ball and the first six of Dragon Ball Z. In the end, both Goku and Gohan power up and change into their normal outfits.
This TV Special has not been released on DVD, and it has not been translated to English either. It was not included on either of the Dragon Boxes.
This film is often confused with the third Dragon Ball Z TV Special, Zenbu Misemasu: Toshi Wasure Dragon Ball Z.
