Right after Dairanger is the Kakuranger tribute having Teruaki Ogawa play another role of his as Ninja Red. I dont know much about Kakuranger, but I do have a feeling that they will make a comparison to KuroKishi for a joke since its the same actor. There could even be a chance for a Ninjaman ranger key to be introduced if possible.
I have a feeling that sword will be the power for the mecha
Next is Megaranger having Hayato Oshiba and Masaya Matsukaze to play as their roles of Megared and Megablue. I have seen over twenty episodes of this series and the team up with Carranger. It would be very cool if they use the Nejirangers for this episode because how awsome would that be. Seeing our new heroes fight an evil sentai. That would probably be very hard though to get all five voice actors though, but if it happens it would make fans happy.
Now another pre zyu sentai series tribute with Fiveman! Toshiya Fuji will return as Fivered and I saw about ten episodes of that series and I really like it. So I may not know a lot, but Fiveman is a series I want to see very badly. The fight scene will probably be awsome because the team will use the Five Tectors.
Next is a big pre zyu series Bioman with Ryosuke Sakamoto as Red One returning. I have seen a couple of episodes and I do know how big this series got with fans. It also got a lot of international fans so this will be a big episode for Gokaiger no doubt about that.
Now the 2nd sentai series will get their tribute JAKQ! With big toku star Hiroshi Miyauchi returing as Big One. I really cant wait for this episode because we will see the master of disguise at work again. Also he is a big star in the toku franchise playing as the Aoranger, Kamen Rider V3, and Zuubat. So seeing a big star like him is going to be a lot of fun.
Now this is the tribute I cannot wait for the Sun Vulcan tribute! Its another red returning, but its both of them! Yes both Ryusuke Oowashi and Takayuki Godai will return and how awsome is that both of the VulEagles will return it will be very interesting to see these two together. I do wonder though how will the fight go because Sun Vulcan only had three members. They should at least have Doc be VulPanther because seeing the three males fight it out as Sun Vulcan will be great.
Finally the last tribute that has been mentioned is Battle Fever J the thrid sentai series and the first one to have a robo. It will have Kenji Ohba who played as Battle Kenya and yes! Kenya is a favorite of mine and I so cant wait also he played as Denjiblue and Gavan the first metal hero so another big toku star will appear. for the mecha power because it will summon the Battle Fever Robo and it wont be a quick summon hopefully I want to see that robo in action because its the first robo in sentai!
So yea they took some cheap shots with using similar actors with Ninjared and Battle Kenya, but its very hard to get actors to play roles again because there could be money issues or something else with their lives. Just be happy there are even any past actors. Im also still wondering if there will be tribute for Changeman, Flashman, and Maskman because of episode 31 of Gokaiger if you saw it you know what I'm thinking about.
