He revealed to Ryo about Asuka's alter-ego as Dyna and his planned to used him to create Terranoid. Despite its success, due to his careless spending of energy, his color timer soon began to blink and he soon fell. Because there were still a few more Sphires left, the Sphires morphed him into his next form, Zeglanoid and attacked the TPC Mars Base.
Zelganoid then began to wreak havoc upon his creators. Ryo tried to brought Asuka to safety but the latter refuse to give up, almost killing himself in the process by transformed into Dyna to fight the monster. But due to his previous drain of light energy, his color timer quickly flashed. Just then, Super GUTS arrived and also attacked the beast. Watching the battle from underground is Ryo and Gondo himself. Ryo then headed towards the "life-force extracting device" to lock herself in and sacrifice her energy so Asuka can live when he un-transforms. Seeing this as an opportunity to redeemed from his mistake, Gondo throw Ryo aside from the device and lock himself in. He then switched the machine on to max frequency and turned it on. Gondo bids farewell to Ryo and performs Asuka's signature thumb up. In a flash of yellow light, the machine exploded, and Gondo became energy, which was then transferred into Dyna. With renewed strength, Dyna managed to turn the tables and defeated Zelganoid. Soon, Zeglanoid exploded, and the base was safe. However, Ultraman Dyna has also then vanished with Zeglanoid after the battle with what's left was the Reflasher, much to Ryo's dismay.

However, Dyna managed to save Ryo from Neo Gaigareid, allowing Super GUTS to fire a special laser that destroyed him, but not Gransphire.
Back in the Kolakerf, Asuka's secret was no longer made a secret though everyone accepted it. Arranging a new plan, they used the Kolakerf to fire the Neo Maxima Cannon to cleared the path to allow Dyna to target Gransphire. Asuka/Dyna successed in the mission, but the victory turns somber due to Asuka being sucked into the wormhole. Along with the others, they believe that Asuka still alive and set on a journey to the Planet of Ultra .
