I am here again with my new theory;

Ben now have Omnitrix but once was in possession of Ultimatrix. Which allowed him to transform not only into alien species but was also able to evolve them.

The evolutionary function works on base of artificially forcing a specie over a period of million years for its survival.

This allows only survival of fittest and hence we get

From

But this all not stops here.....

Evolution never stops.

We now are considering that Omnitrix have evolutionary function(please just consider it true for a minute).Suppose evolutionary function forces specie to stay in stimulation for infinite years instead of million years than we will get

LEGENDARY ALIENS

Such aliens as Legendary Cannonbolt would be able to easily take down thousands of Ultimate Cannonbolt down.

I hope Legendary Alien X would be able to destroy Omniverse just by transformation.And his single thought would be able to create an omniverse inside quark.......

Please tell me about your thoughts.
