I'm getting pretty tired of the many Pokemon parodies that are on here and not to mention mixing Dragonball Z and Pokemon is a very tired and outdated concept and considering I've seen it done better than what I saw here, yeah I'm not very impressed. I could direct you to two other animators who made better Pokemon/DBZ mashups known as Pegbarians and WingDog and they're better because they didn't stray away from what they wanted to parody and they found a way to make the parodies work. Here, you were on track until that FLCL reference which wasn't a problem until Canti came on screen...
Speaking of which, you claimed to want to mash-up several anime together when I could direct you to your Superman vs Goku animation which only focused on them for a minute but then went off track. To be honest, looking back at that you were a lot worse with losing the focus there than you were here which I'll give you props to that. Besides ToonSmyth and Haitam didn't go too far with making uneeded references.
Anyway as for the animation, it's decent and I do like Ash's mom's dancing animation but I noticed that some tracing was used here or some of the things seem a little trached because some of the characters look really off in some scenes. However, I won't blame you for tracing the kame house as I have trouble with drawing buildings myself. I don't mind the CGI animation and I like the modeling as it's much better than mine. However, the animation did seem a bit off but it was good entirely.
For future reference, work on your writing and try to limit the amount of characters you insert in to your animation. Cluttering up a parody with an unnecessary amount of characters from various shows or games tend to kill the mood a bit. Also try to stray away from tracing, too. While it is an easier route, it doesn't make everything look appealing much unless you stylize it a bit to make it fit.
