It's a Future Trunks vs Black Goku episode

That's a nice meme for those who wish to appear more knowledgeable to other anonymous people on the internet.

It's one thing to be Stockholm Syndrome'd into believing you need to see every bit of Dragonball media to the end out of some sense of devotion and closure. Obviously all of those people know that Namek exploding was a thing.

It would be quite another thing to actually willingly tune into the horseshit that the series has become without having the nostalgia over when it was decent to make you watch it.

I seriously hope the latter isn't a scenario for anyone.

That looks like Chevy Chase

Honestly, I'm intrigued just for the plot holes alone.

Why does Future Trunks have blue hair when Normal Trunks has kept the exact same design he's always had?

Why is Mai there, and at the exact same age as Future Trunks when there are no Dragon Balls in their world with which she could wish herself younger?

Why?

A design change, most likely.

The same reason why Cell didn't disappear when his body was destroyed as a larva. There's some crossroading between different timelines.

The former is happening to the entirety of Mexico.

It takes place before the tournament where Goku meets Uub and flies off to train him.

How can it be Future Gotenks if Trunks is fighting him? Do you mean Future Goten?

Yes, that's obvious. I'm asking why bother to change Future Trunk's design but keep the regular Trunks looking exactly the same, purple hair and everything. It's not like people are going to confuse them.


I don't understand, elaborate please

Well, the way time travel works is in Dragon Ball is that actions in the past lead to the creation of timelines that are entirely separate from the main storyline.

Future Trunks was entirely unaffected when Cell was killed in the past (I'm talking about Cell's primitive larva form), so his own indigenous timeline would not have been affected either. IIRC Mai wished herself younger before everybody got slaughtered by the Androids, so Future Trunks will end up with her either way.
