Juken Sentai Gekiranger
Several of the episodes in "Gokaiger" feature and focus on the actions of one of the Legend Sentai. Those episodes are titled in a fashion similar to that of the original series. For example, episode 3, which features "Mahou Sentai Magiranger", has a magic spell as part of the title, while episode 7, which features "Juken Sentai Gekiranger", features one of the nonsense phrases that series protagonist Jyan Kandou would use.
