Blazblue: Take-Mikazuchi fires a laser

Exactly what it says on the tin.

The Gigant: Take-Mikazuchi fires a laser from space, annihlating the 13th Hierarchal City of Kagutsuchi... and, well, much of the surrounding planet it was built on.

How much of it, you may ask?

-

In the words of one Simon Pegg,

"...lots."

The diameter of the Earth varies from 12714 km to 12756 km: for now, we'll go with the smaller of the two values.

12714 km / 2423 px = 5.247214 km/px

5.247214 x 177.89 = 933.427 kilometer wide crater. Halved, that's 466.7135 kilometers for the radius.

Unfortunately, we can't tell what kind of destruction it is: in the game cutscenes, nothing seems to be left, but we can't get a good enough shot to confirm this.

....however, we could use a nuke calculator, I'm pretty sure.

Using this one here, I found that a fireball radius of 466.7 kilometers can be attained with a 11625000 megaton yield: in other words, 11.625 teratons of TNT equivalent, or a low-ish Country level.

Now, how fast is this laser, now?

Here, the Take-Mikazuchi again fires at Earth: this time, though, Rachel Alucard is there to recite some technomagic mumbo jumbo, deploy the Tsukuyomi, and save that poor city from complete obliteration. More pertinent to us, we get to watch the blast get deployed frame by frame.

Now then...

Here, the Take-Mikazuchi is preparing to fire.
Not looking good for Earth.
There's the shot being lined up...
Almost there...!
And there! See that flare, how the beam thickened at the base? That's the laser, having just been fired.
And there it goooessss...
Wait, it's already hit the Earth?
Yes, it has. If you look closely at where the beam has touched down...
You can observe that the end of the beam isn't moving any further at all. It extends all the way down to Earth.
It erupts outwards shortly afterwards. Fortunately, Rachel's Tsukuyomi is already up, causing the shot to deflect.

...yeah.

It takes a mere 0.07 seconds (2 frames) for the thing to travel from directly in front of the Take-Mikazuchi's face to the Earth's surface. But how far is that?

Well, the thing's modeled after a satellite; it's been recommended that I use the figure for science research satellites, which the Gigant: Take-Mikazuchi is most similar to in design and purpose. According to this, these things float around at 3000-6000 km high, so there's our low and high end values. The average: 4500 km: can be our mid-end.

But wait, it's being shot at an angle! That means there's more distance to travel, yeah?

The problem is that, while it appears to be a rather steep angle, we can't get a clear shot of it enough to tell just how much. I can maybe go with 10 degrees as something of a lowball, but it's not going to make much of a difference.

(Plugs values into this calculator; remember, 10 degrees difference on the Take-Mikazuchi's part makes the other angle 80 degrees)

Yeah, our hypotenuses are 3046.3 kilometers for the low-end, 4569.4 km for the mid-end, and 6092.6 kilometers for the high-end. Barely even 1 percent more.

Anyhow,

Low-End: 3046.3 km/0.07 seconds = 43518.57 km/s, or 0.14516 C

Mid-End: 4569.4 km/0.07 seconds = 65277.14 km/s, or 0.21774 C

High-End: 6092.6 km/0.07 seconds = 87037.14 km/s, or 0.29032 C

Relativistic speeds. This thing was probably intended to be a legit, actual laser. No, it's not an outlier, either: Rachel, Jin, Noel, and Ragna have all proven able to react to this thing point-blank, light-based attacks are thrown around fairly frequently in the series, and if memory serves I'm fairly certain one of the characters has a technique with "Light-Speed" right in the name (don't hold me to that one though, I'm pretty rusty).

Point being, this isn't contradicted by anything else in the series.

At any rate, this scales to quite a few people, soooo... yeah.

Final Tally[]

Take-Mikazuchi's Power: 11.625 Teratons of TNT

Take-Mikazuchi's Blast Speed/Combat Speed: At least 0.14516-0.29032 C, possibly up to C
