Changeman, they all became them in 33 (except Green) and all of them in 35. And then them all in a later eisode.
Kakuranger-Red Ninja and Yellow Ninja (Yellow became Black in ep3; Don, Ahim and Joe became Black, White and Blue in ep21) They all became them in Ep33.
Liveman (Don became Green Sai in 12, Marvelous became Red Falcon in 25, Joe became Blue Dolphin in 25 and Luka as Yellow Lion in 25.) The whole team in Ep 30.
As of July 31st, 2011, these were Gokaiger changes they haven't done, as of ep 29 and the movie (they become Battle Fever J). But as of October 15, they have ultimately done them all except for GokaiSilver being MagiShine, Go-On Gold and Go-On Silver.

When this post was made in July 31, 2011, Gai had yet to become AbareKiller, MagiShine, Go-On Gold, Go-On Silver, GaoSilver and DekaBreak. But ultimately, he became Dekabreak in Ep 26, AbareKiller in 29, GaoSilver in 33, MagiShine in 39, and Go-On Gold in 41. He never became a male version of Go-On Silver, only as Go-On Wings. http://www.super-sentai.net/go-kai/super-sentai.html
