Should this be tagged time paradox?

Well, comment section isn't of any use so I'll try here instead. Would a situation like post #656228 warrant the time paradox tag? A forum search didn't show anything except T5J8F8's question that nobody responded to. (forum #38078)

Yes

Okay.

What about my question? *tears*

Actually, I hardly remember asking it, though it seems like an obvious "yes", until considering if use of a "time travel" perspective would actually be a paradox (see: Trunks).

If you mean

Can a character of a future age interacting with characters of past ages be a time paradox, like a grown son in the same pic with his young dad?

yes. Any character of any age interacting with a character whose age does not match that which it should be is a time paradox.

Yeah, what fence and log said. That image is definitely time_paradox.
