Not to mention the speed of light, super-light speed is also possible.

For example, in the 13th episode of Ultraman Ace, after Ace received the fake Ultra signature sent by the Yabo people, he flew at super-light speed and traveled to the anti-universe to the planet Gogda. The same goes for the other Ultra brothers.

In addition to flying faster than the speed of light, you can also teleport. The speed of teleportation is infinite. Compared with teleportation, the speed of light is not worth mentioning at all, but it will shorten your lifespan. Basically every Ultraman can teleport, so I won’t go into details here.
