If Tiga doesn't wake up, then the monster won't wake up either, and the world will be calm and peaceful.
Haha, just kidding. In fact, according to the plot setting, TPC's fighters were not equipped with offensive weapons at the beginning, and it was because of the appearance of monsters that they began to vigorously develop weapons.
TPC was originally a peaceful organization, but with the appearance of monsters, it gradually became a militarized organization, which can be seen from the development of TPC in the two works of Tiga and Dinah.
During the Tiga period, TPC was still led by doves, and during the Dinah period, TPC was gradually controlled by hawks, and the weapons it manufactured became more and more powerful, and even made a super killer weapon like the Nao Max cannon that was enough to compete with Ultraman's light.
Therefore, even without Tiga, TPC's weapon research and development strategy will definitely not change, and even under the threat of monsters, it will speed up the development of weapons, and it is not a big problem to develop powerful weapons that are enough to deal with most monsters.
If you have to talk about it, it is more difficult to deal with boss or bug-level monsters such as Guransfia, Gatanjee, and Goldras, and of course, at that time, I am afraid that TPC will create a weapon with nuclear bomb-level power.
If you want to follow the logic of the real world, even a boss-level monster like Gatanjee may not be able to withstand the damage of an atomic bomb, but the strength of the human side is excessively weakened in the special effects drama.
In my opinion, the actual combat performance of laser weapons is not as good as missiles, of course, it is a special drama after all, and the expressiveness cannot be completely consistent with reality, which is a limitation of interpretation.
In short, even without Tiga, humans can deal with most monsters, but in this drama, Ultraman is the protagonist, and humans are supporting characters, so they have to weaken the combat effectiveness of humans for the sake of the plot.
