Episode 17 introduces Gai Ikari as Gokai Silver. The episode starts out with Navi giving his prophecy, which was finding something or someone "sugoi in silver." This turned out to be Gai, who the others dismissed initially (although Luka found him to be cute). However, he transforms into Gokai Silver much to everyone's surprise and takes out the Gormin. Later, he's able to defeat the MOTW, and the other Gokaigers start questioning Gai at the end of the episode.
This episode reminds me a lot of Genta's debut in Shinkenger. Of course, personality wise Gai is a lot like Genta, hyper and flashy. He's also a wannabee Super Sentai senshi, like Genta was kinda a wannabee samurai, although Genta had a deep friendship with Takeru. I thought Gai kicked ass in his fight scenes and I love the Gokai Silver suit. However, there were two issues I had with this episode. The brief second in which Gai was fantasizing about being a Gokaiger, everyone's personality except for Ahim changed which kinda annoyed me, but this was a minor issue. The real big issue I had was with Gokai Silver's long, drawn out, and over the top roll call. I mean seriously, Gai's roll call is longer than any of the Gekirangers', which is saying something. It really doesn't fit with this show especially when the others have such a short and straight to the point roll call. I hope this was just a one time thing because I don't want to see Gai's roll call stealing the show every episode. About the character himself, I felt for this episode Gai was alright. It's only one episode and there's a long way to go before I can judge his character. I am, however, really interested in seeing the next episode with him obtaining the Zyuranger, Abaranger, and Timeranger grand powers. That will be interesting to see. Overall, I thought the episode was ok, so I give it 7/10. I'm just more interested to see what will happen next.
