Tsuburaya have officially announced the details for (by their count) the 25th Ultraman series, Ultraman Trigger: New Generation Tiga. As you can tell by the title, the series will heavily homage Tiga, which is celebrating it's 25th anniversary. Trigger begins broadcasting on July 10th 2021 (9am, TV Tokyo Network). Veteran toku director Koichi Sakamoto will be head director for this series.
Ultraman Trigger fought against evil 30 million years ago. He managed to seal it away, but expended all his energy in the process and has lain dormant in a red star since then.
Kengo Manaka is a 21 year old botanist on the first Martian colony. When the colony is attacked by a monster he becomes merged with Ultraman Trigger and returns to Earth to join it's defense team, GUTS Select. And judging by the trailer above, he seems to have stolen Go-On Yellow's catchphrase! Kengo will be played by Raiga Terasaka, leader of the boy group Matsuri nine.
Much like Tiga before him, Trigger has three main forms. His default mode is "Multi Type." He also has a stronger form, "Power Type," and a more agile form, "Sky Type." His main weapon is the "Circle Arms" which also has three modes: a sword mode used by Multi Type, a claw mode used by Power Type, and a bow mode used by Sky Type.
Kengo transforms using the "GUTS Sparklence," a gun which transforms into the shape of a more traditional Ultra transformation device. It must be loaded with a GUTS Hyper Key (basically a Gaia Memory with the button in a different position) and he has one for each of Trigger's types.
