Glitter Tiga is Tiga's final form that is achieved when humans or other beings (i.e. Giants of Light) give their inner Light of Hope to Tiga. This form is also called Final Version in some older merchandise.

Tiga's final battle took place upon the appearance of Gatanothor; the master of all darkness which Gijera and Zoiger bowed to. Tiga was defeated by the evil lord and was petrified once again, but he was later revived by the hopes of the children of the world which transformed them into beings of light to merge with the Titan. This rejuvenation allowed Tiga to transform into his Glitter form with tremendous power and destroy the evil god. However, Tiga's victory came at a cost: Daigo lost his power and couldn't transform to Ultraman Tiga anymore as the Sparklence disintegrated into dust. However, Daigo tells Rena he believes that every human could also become light with their own power.
