I may be wrong about the actual reason for this - as ‘double V’ is also quite common - and it may just end up being some kind of ‘well when the printing press came to England’ thing, but:

In the classical Latin alphabet, the letter ‘V’ was not actually representative of what we today recognise as the /u/ sound (or its variants). It was in fact the written form of the /u/ sound (and related variants). So when the W was introduced to the English alphabet, I guess it was indeed a ‘double /u/‘.

This has been a necessary step for over a decade, honestly. Hoping it goes well.

‘Collectivizing power from the wealthy’ also known as… democracy? Is the anti-communist just saying the quiet part out loud here?

Sure, and that will be great I’m sure, but an evil version of a character we’ve just been introduced to won’t hit the same.

So I’m guessing it’s a combination of dun/den/tun etc being a common suffix in a lot of historical languages, and ‘ei’ being an extremely common diphthong worldwide just… leading to a lot of similar-sounding names that also converge in spelling in modern English?

MCU doesn’t really have a ‘proper’ Reed Richards, so the alternate universe Evil Reed from Secret Wars couldn’t work that way. The only brains of the MCU that could fill that role in that plot would be either Stark or Bannon, and the latter is a) still alive and b) already his own foil and his genius isn’t really played in the same way anyway. B-list alternative would be Hank Pym but he’s not been central to the MCU in anything like the same way as the other two.

Honestly I think it might work pretty well story-wise. Though actual reason is just… well, money. And the course correction aspect previously mentioned in these comments.

I’m sorry, but ‘crash when pressing Ctrl+C’ is a hilarious bug.
