The Great Gathering of 11 Sentai: The Glorious Opening Collection was a special episode that introduced Kousoku Sentai Turboranger and celebrated the 10th anniversary of Super Sentai with a teamup of the previous 10 Super Sentai. Himitsu Sentai Goranger and J.A.K.Q. Dengekitai were not included, this was because at the time of the show's debut, Toei had the Super Sentai series begin with Battle Fever J. However, when Toei marketed Chouriki Sentai Ohranger as the 19th anniversary of the Super Sentai series, Toei retroactively included Goranger and J.A.K.Q. as part of the Super Sentai series.
The Turboranger Special has the second largest amount of rangers gathered together, with 53. The largest amount is in the first episode of Gokaiger in which all 34 previous Sentai teams (182 Rangers) appear in the opening. Gaoranger vs. Super Sentai has the third largest amount of rangers gathered together with 25 of them being Red Rangers.
