DCAU - Continental? Island level? Let's talk about it. (TAKE 2)

PapiSavitar5025 · Saturday at 05:52

So going on FOUR YEARS AGO (holy crap), I made a big Superman DCAU revisions thread.
The consensus was to make a big whole DCAU revamp thing following that, buuut that didn't exactly happen (no blame to anyone, I forgot too)
So, I thought I'd make a smaller thread.
The amazing and talented Dark-Carioca calculated this feat for Doomsday.
Initially, it seemed that Doomsday would scale to the full eruption (Continent Level), but there were some heavy contentions against it.
Long story short: We got... Nowhere. But the feat, I believe, is still impressive enough to warrant discussion.
So... Let's discuss.

What were the reservations?

I believe it was the fact that there was a B-plot where Batman was deflecting a kryptonite nuke and it caused large waves to cover parts of the island so it was assumed that the initial calculation wasn’t taking into consideration that a large part of the island was underwater; and it was advised to not use the size of the island in the calc because of that.

Full scene

That makes sense, could the size of the volcano itself be calculated instead?

Around the two minute and ten second mark we see how much of the island sunk. I feel that’s enough for a subtraction personally.

There were also arguments about Doomsday not scaling to the full value, despite being at the epicenter.
That's what I got on reread, even though Doomsday was pretty much smack-dab center in the middle of the eruption.

I’ll be honest

I think the DCAU is long overdue an upgrade

I know of a few arguments and scans out there but I’m not the most familiar tbh

If we manage to hash this out, or argue that the calc doesn't need any adjustments, they could get one.
Hell, the DCAU did just get approved for a Large Country+ feat.

I should note we accepted the volcano end of the calc, which would be around 6-C. Still an upgrade tho.

Hmmmm.... we could solve it using Joseph Joestar's meteor calc.

Just gotta find Doomsday's cross-sectional area (Half of total surface area)

Really?
I thought it was Continental.
Or was that continental scaling to the entire island aside from just the volcano?

You told me if Doomsday was at the epicenter, he'd scale to the full eruption.
Problem is: The island was partially submerged, therefore the sizes used are potentially inaccurate.

Well the values depend on which eruption speed you wanna take. Sometimes fiction can move significantly faster than IRL, so if you're not quite sure yet, you can put it up to a vote with CGMs.

Technically a volcaninc eruption wouldn't be so much like an explosion as it would be uh... a huge slab of dense molten rock slamming you in the face head on.

Which is where linear momentum would come to but even that isn't exactly representative here.

Even then, the island looks similar enough in shape to the IRL representative that Carioca used to not matter.

Ah. Okay.
Are you changing your mind, then? Is 200 m/s preferable to the on-screen speed?

The calculation is usable then?

Looking at the feat the eruption was caused as a chain reaction from Superman hurling Doomsday into the volcano, so maybe the cinematic timeframe could be more accurate. We'll need more CGMs to chime in to confirm, tho.

If we can find a proper cross-sectional area for him without delving into calc-stacking over his body weight, prolly not. But seeing as the DCAU almost never lists weights for these foes, we may not have a choice but to scale to the full value.

PapiSavitar5025 said:

Yes. Both values are mathematically correct.

Ah, okay.
I only ask because you said the on-screen was fine to use before.
Are you able to ping any CGMs?

I’m working on a recalc trying to account for the portion of the island underwater.

According to KLOL, I guess that might not even be necessary.

KLOL506 · 2026-07-05T18:17:40+0100

@AbaddonTheDisappointment @Migue79 @Dalesean027 What do y'all think we should do? Should we use the cinematic timeframe, since it's likely more accurate?

PapiSavitar5025 · 2026-07-06T06:43:03+0100

Rex_Eckles · 2026-07-06T17:06:26+0100

I did the recalc, with both ends.
