Inter Universe (インター・ユニバース Intā Yunibāsu) is the seventh episode of Ultraman Trigger: New Generation Tiga.
Suddenly, a unidentified robot fell from the sky! Following that event, visitors appear one by one. An eccentric alien with a bird on his shoulder. A defense force member that's not GUTS-Select. And finally... another Ultraman!? A new battle for Trigger and GUTS-Select now begins!
Alien Barossa IV stole King Joe STORAGE Custom while throwing random junks at his pursuers, Haruki/Z and Yoko/Space Sevenger. He then summons a Bullton to conjure an inter-dimensional portal that caught all participants involved, but Z was able to spare Yoko/Sevenger from it. In the interdimensional rift, Haruki was de-transformed and had his medals stolen by a particular bird-like creature.
King Joe STORAGE Custom then lands on a different planet Earth, crashing down nearby a construction site. GUTS-Select met Haruki during their investigation on the mecha as the young man introduce himself to the team. Kengo and Akito are forced to drag Haruki to the lab when the latter almost blurted out Kengo's dual identity. With Z barging along into the discussion, the pair from another dimension express the troubles of their current situation and ask Akito to fix the damaged Z Riser at the moment while also providing them an alternative.
Having heard of the discussion through a peculiar radio, Ignis confronted Barossa IV in the middle of his search of the lost Juran seed by showing each others' valuable treasures until he took the Ultra Medals away. In the middle of chasing the alien treasure hunter, Barossa recover his Juran seed to grow giant, using it to attack Ignis before he could go home. GUTS-Select commences their attack on Barossa IV and Kengo heads on transforming into Trigger. Using the GUTS Sparklence created by Akito, Haruki used it as his alternative to transform into Z to join the fight, with Beliarok's late participation seals the alien pirate's fate.
At the end of the fight, Ignis returns the Ultra Medals to Haruki as a token of appreciation for saving his life before he went to chase Barossa's Zandrias companion.
