Direct sequel after DBZ by MCDaveG

[MCDaveG]

With the Battle Of Gods and now second movie on it's way being direct sequels to the manga (tough in the deaf part after Buu's demise),
I thought that I will write down what was my idea of continuation. Maybe it will bore you to hell, as it isn't polished fan creation, which I wanted to do as a manga at first, but job and normal life got in the way.

I enjoyed the GT a lot as a kid, but was later more critical to it. Also, instead of open ended Z, it gives you more definitive ending and as I take only DB and Z as canon, I wanted it to be a sequel from the moment when Goku and Uub fly away.
I'm also writing this, because after some time, I will probably forget what I thought out and I already forgot some plot parts over the years.

Maybe, if you will like the premise and basic idea, I can write down some full fledged story. But my english isn't that great to even acomplish some writing value.
The name I though is simple, it is Dragon Ball Ultimate Battle, meaning the last battle in the story and biggest in Universe.

The Story:
Goku flies off with Uub and they train together in various locations on Earth. Everything goes well, until holograms appear, with mysterious guy in some sort of armor from head to toe (with oriental/chinese markings, but looking more cyberentic and being white), that the time has finally come for him and his nation to assume the rule over Earth and later the whole Universe including Gods and also aims the message on Goku to try to stop him if he dares.
The armor is mainly plot point to hide his identity because he already appeared in the series (in filler actually). The armor is also amplified with magic technology to increase it's bearer strange so he can compete with Goku and co. but the fun is, that the main villain doesn't neccesarilly need it. After the message, mysterious armored warrior attacks Goku and Uub. His armor is simmilar to the villain's, but with a lot more simple design.
They fight with Goku not being Super Saiyan and the warrior being slightly stronger, until his armor starts to glow and he fights and almost kills Goku, until Uub joins him and they win.
In the same time, groups of simmilar fighters appear in God realm, taking Kaio's and Kaioshins trough the portals to the main villain and imprisoning them.
With universe starting to lose it's normal order, Goku and co doesn't know what to do. Until 7 portals open on Earth from which 7 powerfull wariors emerges.
The villain contacts Goku and tells him, that these seven warriors are his champions, who hold one key each, from the door that leads to the dimension he resides in.
If Goku and his friends can prove themselves by defeating the champions, they can reach him and he will destroy them himself and take over the known world as a ruler, as there are no others in the universe, who can stop him.
There is not much time, as the universe crumbles with the planets colliding and other crazy stuff, so the group separates and everyone goes to fight the champions one on one. That is Goku, Uub, Vegeta, Trunks, Gohan and Goten.
Which leaves one of the champion being strong as hell and the main character to get him is Vegeta, who aqcuires SSJ3 in the process.

That is first part of the story, as the second goes in the different dimension. It's not actually dimension, but I won't give the details away yet.
Damn, if I had more time I could draw it as a manga.
