Future Gohan could've been smarter

I believe Gohan hadn't known about the chamber before Goku introduced it.

Gohan not having any children is probably due to a combination of things. He could have been too busy training to meet anyone. He didn't want to meet anyone because he didn't want to make them worry for his safety. The darkest option is Gohan did meet someone and they did have a child, but they were both killed in one the cyborg rampages. No one really knew when or where the cyborgs were going to attack. If Gohan did have a family they could have easily been killed or the fear that they could appear anywhere at anytime could make him too afraid to attempt to have a family.

I doubt he knew about the time chamber. It is simply possible Popo never told him about it. Goku was the one who thought to use it in the first place to get quick training in.

It's possible that the Z-fighters chose not to go to King Kai's this time around. Piccolo was killed as well, meaning Kami and the Dragon Balls were gone too. Without the possibility of coming back to life in sight they may have simply chose to move on to Heaven instead of training with King Kai again. Vegeta got sent to Hell. He committed too many sins to have been allowed to keep his body to train with the Kais or move on to Heaven. King Kai has the whole Northern sector of the universe to watch over. Without any of the Z-fighters coming to him he simply never learned that Earth was under siege. Since 17 and 18 were only a problem for Earth not the universe they simply were too small to catch the notice of the other gods. Baba may have either been killed or left Earth for her own safety.

Gohan and Bulma had no idea where New Namek was and probably didn't know how to contact King Kai for help in finding it. Without that knowledge they would be forced to wander through space aimlessly. That is a dangerous risk to take. They could run out of fuel or food. They would need to know where inhabited planets that are space faring to help them restock on food or refuel etc. Goku not teaching anyone Instant Transmission bit them all in the ass. If at least Gohan knew it he could have gone to Otherworld on his own and got help from King Kai. 

You mean marry her vignette1.wikia.nocookie.net/dragonballfanon/images/6/6e/Future_videl_by_victor0822_%28color%29.png/revision/latest?cb=20160507160236 and have her vignette3.wikia.nocookie.net/dragonballfanon/images/7/7b/Future_pan_%28color%29_lower.PNG/revision/latest?cb=20160728075122 ?

Yeah it would be epic

Why not? Theire clean

You mean because the amount of SSJ7's there?

DB Fanon Wiki is pretty much awful as a whole. Awful pictures, awful articles (saw one where their character's article had pictures of Chaiotzu as their character), some awful concepts, and generally just terrible.

Anyway, I really don't see Gohan as the type who would hook up with a woman for the sole purpose of manufacturing children to fight androids. He'd likely wait until the world was safe before even attempting to date.

How are you today my friend! I just wanted to say that according to the rules, we're not allowed to talk about rape and/or molestation. We can talk about making love though!

All right, my point was twofold:

1. Making children for the sole purpose of fighting, while practical, is morally reprehensible. You're essentially making people to be used solely as weapons. What happens when your ultimate weapon succeeds, and all they know is how to fight?

2. It takes ~18 years to make a human capable of fighting well, even if you trained them from birth. Without the Hypersonic Lion Tamer, that's ~4 years of hiding with an irrational child (after this, they should have learned enough to STFU when needed), 15-18 years worth of food resources, and above all, time. The androids could find you at any point during those years and end both you and your offspring. With the HTC, that's time you're spending in a blank white room with resources that may or may not go bad before your time is up, with no other human interaction than you (and possibly any mother or sibling(s) that come in with you). You could very well end up with a psychopath worse than the androids.

I'm saying Gohan would rather deal with the androids on his own as a matter of practicality. I'm pretty sure the only reason he trained Trunks is because Trunks is also half-saiyan, and would really be the only other person on the planet who could possibly stand up to the androids. Tenshinhan simply prefers solitude.

F. Gohan's training seemed to be patchwork at best, as he did have Piccolo's training and mentally sparred with Krillin on the way to Namek, but he lacked the three years training for the androids F Trunks got them. As such, Goku wasn't around to guide him, and he may not have known there was anything past SSJ. He might have hit on the idea to stay SSJ all the time to master the form at some point, but he isn't the fighting savant Goku is.

That said, I agree. Trunks might have been able to go SSJ without Gohan dying, and the two of them, once trained up, would stand a solid chance against the androids.
