Do you think that would be good idea if Producers of DB, made a serie about the original one?

If they do I'll set tyhe serie in the Drgon-human wars and I'll change the behavior of original DB and Original Beau. and I will set the end of the series 3000 years afters when a teen Connor Penn gets the amulet

Sure, it would be fun to see a series on the original dragon-human war. We've talked about this a bit here and there on this forum. In the thread titled Is Dragon City on Earth? skip down a ways to where I talk about time travel and prophecies in the show "Babylon 5". In my posting a bit further down, I propose having Mortis, Artha and Beau travel back in time (using a suitable ancient device Mortis has been keeping just for the occasion) after having defeated Word in the present day. Mortis then becomes the dragon priest who makes the prediction about the second dragon-human war and another gold dragon choosing another Dragon Booster in the future (since it's all just history to him at this point), while Beau assumes the role of the last gold dragon in the first war and Artha his chosen Dragon Booster. We then get to watch them fight the first war and even see the now adult Artha leave the recorded message to himself that he plays back in "The Chromatic Dragon". And of course Mortis would then record a message that gets delivered to Connor that fateful night in episode 1 telling him he has to assume the identity of Mortis and of course he passes the time travel device on to himself as well so he'll have it when it's time to complete the time loop and travel back to the first war with Artha and Beau. Wouldn't that be cool?

I doubt anything like this will ever get scripted, but it's fun to think about anyway.

Sure
that sounds as back to future, but I was thinking as first SW trilogy, how all started, why human-dragon war started and how all started

We must remember that the Original Dragon Booster had doubted himself, just like Artha Penn. But he said, "But I have to try."

I'm not trying to be rude, but are you posting to these very old topics, just to add to your amount of posts or your rank? If you are, then you shouldn't, because it clogs the board and makes people think these are new topics they are responding to. Everyone adds to old topics sometimes, (they may have just thought about something or decided to share information) but to do it continuously, is taking advantage (example: responding to post questioning whether Conner and Mortis are the same, when the answer has been known for a few years and topic has been non-active since 2005. Also, you responded to the "is the show popular" topic which has been dead since 2005, with an answer that is irrelevant to the question and was-as you pointed out- already posted by ArthaPenn_1995 under another topic). If you are doing this to add to your amount of posts, please stop. If you are not, then I offer my apologies.
