What is the character on the left saying? I can read the character, but I can’t understand what that single sound is supposed to mean.

tl;dr: He is agreeing with what Doraemon is saying.
Detailed explanation: The character on the left (Sewashi, Nobita’s grandson from the future) is basically repeating the last bit of what Doraemon is saying. 〜な (as well as 〜ね) ending is used to imply that you want the listener to agree with you. If they agree, they would say そうだな、そうですな (less common)、or そうだ・ですね. We can just shorten it to な or ね.
For fellow Canadians, it’s like saying:
“He’s not very bright, eh?”
“Yeah, eh.”
I just realised you are the OP on this and the last post I commented on, and you’re posting questions and answering them yourself to provide examples. Derp on my part.
For anyone interested in why, Nobita (right) is already aware Doraemon (middle) is from the future and should understand the possibility of meeting his grandchild when time travel is available. Hence Doraemon calling him an idiot.
Haha, yeah, I had to “fake” activity to get the ball rolling. I really appreciate you joining in and adding more context!
Oh thank you. In that case excuse the pun but
k0e desu
k0e san
Just for fun, let’s see how Google Translate did on this:

(btw, I’m amazed how closely this work resembles Tezuka’s style!)
Won’t be losing my job to Google Translate just yet, it seems lol
It’s also convenient between japanese and English that “ga aru mon (mono) ka” is an established colloquial phrase. Both languages have the equivalent phrase “is that a thing/nah that’s not a thing”
