The Transylian War 

In the enhanced episode of "The Return", It's revealed that the Transylians once shared a planet with another viscous alien species called the Vladats. The two species fought each other in a race war until the Transylians wiped out the Vladats with energy stolen from captive Pyronites.

Should we include this? The last time I did, it was removed.   

Well...since there is no objection...

Well, If you have TW On Demand, look under Kids>Cartoon Network> Ben 10, you will see what I'm talking about. Do it quickly though, the episode is only there for a limited time.   

It's not terribly relevant. So they had a war, it's not a big deal. We haven't even seen the opposing species. —  (T | C)
