Ultraman Tiga Gaiden: Revival of the Ancient Giant (ウルトラマンティガ外伝古代に蘇る巨人 Urutoraman Tiga Gaiden Kodai Ni Yomigaeru Kyojin) is a direct-to-video special set many years after the end of the original Ultraman Tiga series, in which Daigo Madoka (human host of Ultraman Tiga) has a son with Rena, named Tsubasa Madoka. Tsubasa is a member of a new team, Neo Super GUTS, the successor to the original Super GUTS. This story is set in the year 2038 (18 years after the events of Ultraman Dyna).
This side story takes place after Ultraman Dyna. The protagonist, Tsubasa Madoka, is part of the defense team after Super GUTS, Neo Super GUTS. Then, due to time travel, Tsubasa ends up in an ancient civilization period 5000 years ago, before the start of Ultraman Tiga.
In the beginning of this film the narrator explains that 5000 years ago a giant of light protected this particular village from a monster but disappeared after that. One day while returning from a mission with Neo Super GUTS, Tsubasa (the son of Daigo and Rena) is caught in a sudden storm and encounters a monster. Tsubasa tries to contact Neo Super GUTS headquarters, but a wormhole appears and sucks in both of them. The two return to the past, 5000 years ago where Tsubasa crash lands into a mountain, the nearby villagers, one of which is a boy named Amui, rescues Tsubasa, but to their horror, afterwards the same monster that attacked Tsubasa attacks the village. On the other hand, a wandering monster hunter stumbles upon the legendary Sparklence beside a monster she just killed. Not knowing what it is she keeps it but when she approaches the village under attack the Sparklence starts to shiver. The village's wooden defenses are no match for the monster and the village is heavily damaged with the defenders of the village trying to confront it with spears. It turns out the monster was 'summoned' to this time by a sorcerer who wanted to prevent the revival of Tiga by destroying the golden pyramid in which his remains lay petrified (the very same one Daigo enters and discovers Ultraman Tiga in episode 1 of Ultraman Tiga).
When Tsubasa sees the Sparklence fall out the monster hunter's bag, he instantly notices it looks like the one his father used to transform into Tiga. He takes it away before the monster hunter can object and transforms into Tiga. The monster is defeated easily but at the end Tiga disappears as Tsubasa was not destined to truly wield his power, and the whole village is devastated. Later Amui tells the village he saw the giant of light, but nobody believes him until the defenders state they saw Tiga too. Hearing this, one of the seers in the village claims the prophecy is coming true and soon someone in their village will be the one to awaken Tiga. Despite their triumphing over the first monster the sorcerer then sends his strongest monster and his two acolytes to attack the pyramid once again. The villagers with help from another village's elites and the monster hunter fend off the two minions but Tsubasa fails to defeat the monster Dogouf who stuns Tiga with a kick to the face.
Tsubasa reverts to human form, exhausted and the Sparklence is almost trampled by Dogouf but Amui saves it and he turns out to be the one who fulfills the prophecy. He uses it to transform into Tiga to stop Dougouf using Tiga's Power Type finishing move after a tough battle. Tsubasa then fixes his jet and returns to the future with Tiga watching over the village ever since. Towards the end, the narrator then says: "Thus, this village also became known as the Village of Tiga, and Tiga protected it in the years to come, but the memory of this village also became forgotten with the passing of time..."

- The VHS (for purchase or rental) was released on in January 25, 2001, 31 years from the day of Eiji Tsuburaya's death.
- The DVD release was released on May 25, 2001.
- The extended edition of the movie was released in November 26, 2004.
- The extended/completed version is later available in the rest of the releases, such as the "Tiga / Dyna / Gaia Memorial Box The Final" DVD Set in November 26, 2007, and the "Ultraman Tiga Complete Blu-Ray Box" in September 24, 2014.
- In Malaysia, the original 2001 DVD version is released by Speedy Video. The DVD also features an additional Malaysian-English and Malay dubbing tracks.
- Mill Creek is set to include it in their Ultraman Tiga box set.
- The defenders of the village and the elites that help the main characters are the same actors that portrayed GUTS in Ultraman Tiga and Super GUTS in Ultraman Dyna. Although not all of them were present, below are three which appeared:
- From GUTS: Mio Takaki as Izare's Shrine Maiden, Yukio Masuda as one of the many defenders and Akitoshi Otaki as the leader of the defenders portrayed Seiichi Munakata, Masami Horii and Megumi Iruma respectively.
- From Super GUTS: Toshikazu Fukawa, Nobuyuki Kase and Joe Onodera as the elite villagers portrayed Toshiyuki Kohda, Kouhei Kariya and Tsutomu Nakajima respectively.
- Although Tsubasa is Daigo's son and may have the DNA required to transform into Tiga, he is not able to do so to its fullest potential. Therefore his transformation barely lasted a few minutes the first time, even less the next and was unable to grow in similar size with bigger Ultra Kaiju like Dogouf. In addition, he didn't seem able to change types like Amui or his father.
- Since Amui can transform into Tiga successfully, it is possible he is an ancestor of Daigo.
- This is futher implied by how Mahoroba's appearance is identical to Hikari Madoka, suggesting that Mahoroba and Amui have children together after the events of the film, who are the ancestors of Daigo.
- The time period that Tsubasa and Jomonoid are sucked into seems to be the Jōmon period of Prehistoric Japan around the year 3000 or 2962 B.C.E..
- Daigo was meant to return, but his actor, Hiroshi Nagano, had scheduling conflicts. Because of this, his son Tsubasa was created to replace him.
- This special was later featured in New Utraman Retsuden episodes 80-81.
- The shape and carvings of the stone in the village resembles the Bronze Sparklence.
- To date, the spin-off has yet to be released as part of the TSUBURAYA IMAGINATION's streaming lineup.
