Gai Ikari is Gokai Silver, the Sixth Ranger in the 35th Super Sentai series, Kaizoku Sentai Gokaiger. He and his team joined forces with Gavan in Kaizoku Sentai Gokaiger vs. Uchuu Keiji Gavan: The Movie.
To be added
Gokai Silver is Gai's first and default/base Gokaiger form. It is from this form that he transforms into other rangers of the past.

As Gokai Silver, Gai was given access to the powers of the fifteen 6th rangers. Joining the rest of the Gokaigers, he now has access to the Gokaigers' treasure chest of keys and theoretically may transform into any Ranger he chooses. However with his link to the 15 warriors, an obvious preference for their forms or hybrids of their forms is seen. He has the ability two fuse any two Ranger Keys.
