Notes:

 * I know no one likes ben 10 omniverse because of the different art styles but i would ben 10 is perfect as it is no matter how many fans hate it, I think its good, but you shouldn't judge people by their cover. And yes, i like the omniverse series.
 * I was originally gonna add the ben 10 reboot instead of omniverse, but after a look at it, i had the same reaction like when Michael Bay made a Voltron movie. So i had to add omniverse instead.
