Ben 10: The Phantom Ship

After the events of Ben 10 Omniverse, an unknown presence has arrived in space and claims to steal the keys hidden from the universe that lye within inner space. Ben must put away the rest and get back in the action. However, his omnitrix was stolen without trace, so a new, powerful replacement is given called the Phantomatrix. With a team of 4, Ben must stop this menace from destroying his town.

The Phantomtrix
The Phantomtrix, short for phantom ultimatrix, is by far the most powerful omnitrix Ben has wield ever. It has a search engine for aliens to make selecting easier. It also has the master control set by default. However, there's a chance that it can corrupt Ben forever.

Aliens
While 90% of Ben's aliens are all the aliens from over the years, he has collected a couple new ones (New aliens not been revealed yet).
