Key points
[HIDE]-Asuka is the one who tells Zero to go to the other world
- In Dyna's world, they are celebrating the achievement of Asuka when some leftover spheres attack the base
- Taiga and some spheres get captured by bat seijin
- Zero is wondering why Earth has no humans when bat seijin returns, battle commences.
- Zero merges with Taiga
- Bat seijin inserts the captured spheres into zetton
- Lame scenes of Taiga and mute boy running from the monster before Cosmos appears in front of them to subdue the monster
- For some reason, Zero knows about Cosmos already (Never explained why)
- Bat seijin summons 2 monsters to attack, Musashi transforms but is losing. Zero tricks Taiga into transforming which backfires because without his cooperation, Zero can't transform to his full size but they still manage to win (though Zero gets totally humiliated)
- Musashi and Taiga learn about Dyna from team U but do not know his fate
- Zetton is unleashed the next day and attacks the base, Musashi transforms to protect the base but is overwhelmed by zetton's attacks (Cosmos has the most screen time and number of transformations in this movie but it is never revealed how he came to this world)
- Dyna's fate is revealed when his stone statue is seen
- Taiga finally accepts his duty as an ultraman when he finds out the truth about Team U being a fake team
- Zero and Cosmos fight Zetton, Cosmos gets knocked out in the middle of the fight leaving Zero to fend for himself
- Dyna is revived as glitter dyna and revives cosmos (just guessing cause Dyna was completely gold)
- the 3 ultras do some damage to zetton before defeating him with a powered up ultimate zero attack
- Bat seijin merges himself and his spaceship with zetton to create hyper zetton
- The 3 ultras are defeated and Zero 'dies'
- The 3 men do not give up, tranforming again but this time into Saga (wonder if Noa is involved)
- Saga defeats Hyper Zetton and all the humans are freed
- Musashi returns to his own world, Asuka makes a brief return to his world, telling his comrades they will meet again before leaving again and Taiga decides to stay in Team U's Earth
- Possible hint that this is Zero's last appearance as he says farewell to humans[/HIDE]
