Plot

At night, a strange particle rain from the sky, causing various mobile devices to go haywire. It spreads quickly to a global-scale cyberattack that threatens all forms of technologies the next day. In the midst of TPC branches experiencing the attack, the entity known as Dada made themselves known to GUTS-Select as they hacked into Nursedessei's systems, forcing its crewmembers to switch their control systems to manual while Nanase uses VR to fight off Dada's influence through an 8-bit style gaming platform. Tesshin managed to stop Dada from firing the first Nurse Cannon while Kengo and Haruki were forced to interrupt the second firing attempt on their own at the emergency panels. Seeing how GUTS-Select members managed to fight back, Dada hacked the King Joe STORAGE Custom and forced it to fight against Trigger and Z. A few Dada materialized in Nursedessei to attack its occupants, but they were killed by their opponents, including Yuzare in Akito's lab.

Dada materialize itself as a giant to participate in the fight against the Ultras. While transferring its essence into King Joe SC, Captain Tatsumi fired Dada's core, leaving the Ultras to forcefully scrap King Joe to put an end to Dada's reign of terror. After gathering King Joe SC's remains, Haruki gets Akito's permission to keep the GUTS Sparklence while his Z Riser is still under maintenance, allowing him to return to his home dimension with Beliarok's help. Akito returns to his lab after having lunch with Kengo to discover that Yuna is slowly growing awareness Yuzare's presence.

Trivia

• In a 2023 joint interview, Kiyotaka Taguchi and Keigo Koyanagi shared their fondness for Ultraman: Towards the Future and Ultraman: The Ultimate Hero. They were particularly drawn to the unique atmosphere of "Japanese stories unfolding overseas," which gave those series a subtle sense of realism.
• The Dada variant introduced in this episode, designated "PDO-3," was named as a playful nod to its origins. The "P" comes from Powered, referencing Ultraman: The Ultimate Hero's Japanese title, a reference to the original series—and "3DO," the game console .
  • Koyanagi recalled how, during the 1990s when both series aired, electronics stores often had demo units for Ultraman: The Ultimate Hero on 3DO consoles. When planning to include a Powered-inspired Dada in the episode, Taguchi wanted to distinguish it from the original and decided to give it a slightly different name. During a lighthearted conversation with Koyanagi, the name "PDO-3" was born.
• Compared to the original Powered Dada, PDO-3 features a larger head and a more slender body. The suit used for PDO-3 is, in fact, the original costume from Ultraman: The Ultimate Hero, which had been shipped back to Japan after filming in the United States and has been preserved in near-original condition. However, the original head mold no longer exists.
  • Although the suit appeared to be in decent shape externally, long-term storage had caused material shrinkage, raising concerns over whether anyone could still fit into it. Fortunately, a slim stunt performer was available during production, and the suit fit perfectly—making PDO-3's comeback possible.
  • During Ultraman Trigger, the production team considered recreating the original Powered Dada head for the character's return. In the end, they opted to craft a new mask based more closely on Mahiro Maeda's original design sketches.
