I doubted this, so I tried it. I haven’t used google for ages, so I first had to search “google” in DDG, then I went to the main page. When I started typing it in, it suggested the full text of the search, so I thought it was even less likely that it would work like the OP said - that even if it had been the case that it previously did that, so many people have self-evidently done that search that the results would now be correct.
But no - there it was, right at the top - “While there are 54 recognized countries in Africa, none of them begin with the letter “K”. The closest is Kenya, which starts with a “K” sound, but is actually spelled with a “K” sound.”
And with that, I’ll contentedly go back to not using google.
Huh.
I had no idea Marvel Groot was that old.
That seems to make it more likely that it’s not a coincidence though, particularly since while Marvel Groot existed, he was still very obscure. I can see Moorcock slipping the line in, and even giving the character that name so he could slip the line in, just for a bit of amusement.
