Ultraman Wiki

The Terrible-monster Attacking Crewテリブルモンスターアタッキングクルー (超獣攻撃隊 Teriburu Monsutā Atakkingu Kurū, Chōjū Kōgeki-tai), abbreviated as TACティーエーシー (タック Tī Ē Shī, Takku)[1], was the Earth defense organization during Ultraman Ace's time on Earth. They suddenly made themselves known to the public when the Terrible-Monster Verokron appeared. Their main HQ is based in New York City, and several subordinate headquarters are located in the South Pacific, based in Europe, Africa, and the Far East (Japan). They are always scanning for Terrible-Monster activity with radar, and study day and night to create weapons and tactics to repel the Terrible-Monsters. The number of weapons that were developed by TAC was made to be the best, the kill count of Terrible-Monsters and space beasts boasts performance equivalent to that of UG and ZAT. In addition, TAC's weapons have been able to give a large amount of damage to a few of the Terrible-Monsters, that allowed Ultraman Ace to achieve victory. In the 10th episode it was mentioned that they used a publication from MAT's files, thereby suggesting an association with the previous attack team MAT.


TAC Logo

The squad that helps Ultraman Ace is TAC (Terrible-monster Attacking Crew), which was formed by Captain Goro Ryuh. Members of the crew were Ichiroh Yamanaka, Tsutomu Konor, Kohzoh Yoshimura, Seiji Hokuto, Yuko Minami, and Noriko Mikawa. They have access to all documented Kaiju attacks from the past defense teams and usually use these to assist them in their battles.


Ultraman Ace

The 5 Ultra Brothers arrive at the Earth together in episode 1 when the two humans were revived. Ultraman Ace gives them the ring and merged with their bodies. Both soon join the defense team in fighting off the new era of monsters.


Far Eastern Base's location

The Far Eastern Branch Base (極東支部基地 Kyokutō Shibu Kichi) is in Yamanashi Prefecture in between Aokigahara and Fuji Five Lakes. The base's facilities are cleverly camouflaged by using the terrain and natural ostensibly, while the entrance is disguised as the weather station.

The main command room is located underground (bathroom facilities are also directly connected to the main room), it includes a library of ancient literature references, various laboratories, a shooting training field, the central atom power chamber, the hangar of large hand made missiles. A Terrible-Monster radar, a variety of welfare facility buildings, a general conference building, and a research building all exist on the ground-level portion of the base.

In addition, for protection against Terrible-Monster attacks, the base has been enhanced with defenses of the very best equipment, such as a large-scale field gun, and 4-twin and 16-twin rocket launchers. In spite of its top defenses, Terrible-Monster and aggressive space-aliens have managed to compromise its security, leading the base's front grounds to become a battleground between the invaders and Ultraman Ace.
