After waiting for a decent episode of Ben 10 Alien Force, we finally got one from this one. Telling the story on why Kevin joined the group in the first place, other than being with Gwen of course. We also get to see how more developed he is from a pyschotic bad guy to a tough guy anti-hero with a soft heart. Changing Mike into this misshaped being was also a great idea since I never liked the guy when he first appeared. We also get to see more of the Kevin and Gwen love was also a very sweet twist the writers came up with.

mike morningstar made in awesome roll.Once I saw the dude in the mask their was no telling who that could have been.the reason i think their was character development.Is because kevin and gwen almost kissed,ben knows the master lock on his omnitrix and we finally know about kevins dad and how he faked a plumber.The other reason why I loved this episode is because goop and chromastone are my favorite aliens i mean who does not like them they are awesome.Blah blah blah blah blah i know thats alot but this episode was the bomb when i saw chromastones new transformation it was the best one of them all.

Now this is the way to start a season. A high-level Plumber appears, accusing Ben, Gwen and Kevin of impersonating Plumbers, a felony under galactic law. The kids naturally take exception to this, leading to the episode's first action piece. The Plumber's power is impressive; he bats Kevin aside like a rag doll. Goop's counter attack is equally impressive. The four of them reach a kind of stalemate, with the Plumber warning the kids to stop their vigilante activities or be sent to the null void. We soon learn that this has all been a setup engineered by Mike Morningstar, who now calls himself Darkstar. He's far more powerful than he was at his last appearance in the series, and he needs vast amounts of energy to sustain himself. The Plumber, Ben, Gwen, Kevin and even a Highbreed lord are on Darkstar's menu. The battle that ensues is eye-popping, arguably the best of the series. Ben has become much more formidable, switching alien forms so fast he essentially combines the powers of Echo Echo, Spidermonkey, Jetray and Humongosaur. Lots of funny quips, and we even get some character development involving Kevin. This is B10AF at its best.

This episode was simply one of the best so far. It had a great story a new character and a very interesting plot. You learn more about Kevin and get to see Ben turn into 5 aliens in 1 episode. Usually he only turns into a couple but It was a lot better this time. Also Mike Morning Star returns as Darkstar which is pretty cool. If you didn't see it and you wanted to know Ben turns into (in order) Cromostone, Goop, Humungasour, Echo Echo, Spidermonkey, and Humungasour again. I wasn't that crazy about the Alien X episode because I expected more from it, but this episode definately redeemed itself. If you stoppped watching the show because of Alien X start watching it again cuz it's back and better than ever!
