Takeshi's Castle

History
Takeshi's Castle (風雲！たけし城 Fūun! Takeshi-jō, literally Showdown! Takeshi Castle) is a Japanese game show that aired between 1986 and 1990, on the Tokyo Broadcasting System. It featured the Japanese actor Takeshi Kitano (also known as Beat Takeshi) as a Count who owns a castle and sets up difficult challenges for players (or a volunteer army) to get to him. The show has become a cult television hit around the world.[2]  A special live "revival" was broadcast on April 2, 2005, for TBS's 50th anniversary celebrations.

Noteable Episode
In one noteable episode, General Tani managed to take over Takeshi's castle. Beat Takeshi and his advisor Sonomanma Higashi gathered an army outside of the castle. (Not the first time this happened.) The unique difference is this time, a varity of Ultra Kaijus appeared to help Takeshi reclaim his castle and even lead the charge when the army had to climb over the first obstacle, effectively destroying it with various beam weapons.

Near the middle of the episode, General Tani has recruited the Ultra Brothers to help defend his seat in the castle. Towards the end, the entire army of Takeshi stormed the castle to take it back, fighting the Defense Troops in tanks with patenated squirt guns.

Ultraman
Ultraman has a history in the show, not just the one where Tani recruited him. Ultraman appeared to help the children progress in the Children's Only special. In another episode, he replaced General Tani (for unknown reasons).

Trivia

 * Godzilla himself appeared in some episodes for comedy skits.
