well like they made Gwen ugly with a voice of a stuffy nose, in Alien Force, and Ultimate Alien, where the aliens have the same voice, and Ben forgets his past self for too long and would remember some certain details from the original series!
you know Dee Bradley Baker voicing all the Aliens in Alien Force, and Ultimate Alien, and Ben forgotton that Vilgax had light green spots, and had that raspy voice, and that Dr. Animo was Grandpa Max's age but now looks younger, and has Yellow Eyes, unlike the original version! More important, he forgot what the younger Version of himself looks like, I'm telling you that Paradox has been alternating time, images, and I think Ben's brain!
2. ALIEN FORCE WAS 5 YEARS AFTER THE ORIGINAL SERIES, OF COURSE HE FORGOT VILGAX HAD LIGHT GREEN SPOTS AND THAT VOICE. EVERYONE WAS REDESIGNED IN ALIEN FORCE! ANIMO WAS REDESIGNED, VIGLAX WAS REDESIGNED, AND BEN... I DON'T EVEN REMEMBER WHAT I LOOKED LIKE WHEN I WAS 8. THAT WAS YEARS AGO. ITS NOT A BIG DEAL.
Well it's not, but Ben might need those memories, like when he met Ben 10'000 again in Ulitmate Alien, it was revealed ihe was not Ben's future version, and also well you may not like to hear it, but it shows that the redesign is taking control of Ben's Past Present, and Future, it's as if it was the original animation, and Gwen's color is Blue not pink, that's Charmcaster's color, I sense that something is wrong!
