@TheWindel@KoL *Name Kerflufle.
Yes, KoL has it exactly, I meant KoL.
@floodtalon Alright, are you ready for some Fermi estimation? Cause buckle up.
Let's say Miyu's mech weighs 1/2 as much as an M1 Abrams. They're both heavily armored fighty vehicles. The Daimyo is 16 ft tall to the 8 ft tall M1 Abrams, but an M1 Abrams is 26 feet long to the Daimyo's probably 4-5. That puts the Daimyo at 30,000 kilograms.
Let's say the Daimyo jumps off a two story building, and lands sword point down on Henry. This is an unlikely scenario, but it's about how high the Daimyo could pull off a superhero landing from without damage, making it a good measure of the total power the musculature can withstand and put out under optimal scenarios, if everything lined up absolutely perfectly. A quick bit of math reveals that Miyu would deal about 180,000 Newtons a second from this impact, (30,000 kg * 6 m/s). And let's say her super sword provides about a 10x multiplier to that effective force.
So, 1,800,000 Newtons of effective force.
Let's round up, and call 2,000,000 Newtons one "Miyu Unit". Also you should note that I have rounded up on everything glossed over in the "quick bit of math." We are being generous. Now, from now on, I'll start rounding down to find a minimum of Juno's power.
Let's consider how hard Juno hits. Well, we do know that she decelerated without any difficulty the Daimyo Super version from full speed to zero so fast it seemed instant. We'll call .1 of a second an instant, as we've got people with hyper reaction speeds. Some quick math and an assumption about it's full speed (let's say 100 mph, which is rather slow on this battlefield full of speedsters so fast they leave after images), that's about 132,000,000 (30,000 kg * 44 m/s * 100 to go from momentum to force) Newtons a second. Or, 66 Miyu units.
Uh oh. A situation in which Juno wasn't even trying, and she didn't even consider her attack a direct attack, and was surprised the mech came apart, is 66 times Miyu's maximum damage output.
But this was not Juno's power when she's being serious. When she attacked Miyu directly, her strike was said to have the power of a small nuke? How much power is that? The smallest nuke we know of is W54, a tactical type. The only type that was generally consistently successful? Six kilotons. How much is six kilotons? 24 Terajoules. Terajoules. Say that to yourself. Terajoules. 24,000,000,000. Now, joules and newtons are not the same. So, let's transform Miyu's earlier newton's into joules by finding what her kinetic energy was (.5 * 30,000 kg * 6^2 m/s). We get 5,400,000 joules after we apply the x10 from the sword. We'll round up to 6,000,000, with our general being generous for Miyu and stingy for Juno. 24,000,000,000 is 4000 Miyu units.
But wait! You survived an attack from Juno after she transformed into Jorm! Let's put another x10 on that, because her speed went from "fast enough you can still dodge if you're at least partly speed type" to "fast enough it looks like teleportation".
That puts the strength of one of Jorm's attacks at 40,000 Miyu units.
Unless Miyu increased her strength by at least four orders of magnitude, she's not going to even start hurting you.
