Big money! Big fight scenes! I love it!!!
This is absolutely one of the most amazing pieces of Flash I've even seen. Easily the most stand-out aspcet of this movie is the professionally animated Vegeta (you used 3D Studio MAX...wow).
Voice acting is excellent; Scrooge McDuck and Launchpad McQuack sound like their original DuckTales selves (though Vegeta's voice changes from scene-to-scene).
I love the South-Park-esque feel to the realm of Duckburg, which you've retained from your previous DuckTales Flashes, and seeing a well-animated Vegeta clash with this world adds to the humor (Vegeta's foolish pride adds even more).
The fusion of DBZ attacks and powers is funny as heck. Huey's sacrificial attack from Chao-Zu, Vegeta borrowing Captain Ginyu's body swap power, Dewey and Louie's Fusion Dance, Super Saiya-jin Vegeta, Vegeta's Final Flash, and Christopher Walken's Kamehameha. Seeing "Scroogeta" is funny, with him being a well-animated Scrooge.
I also love all the references you threw into this movie. Here are the ones I can pick out:
*Star Wars
*Superman (Vegeta from planet Krypton?! ROFL)
*Matrix ("Stop TRYING to hit me and hit me!")
*The Flintstones (The Great Gazoo stained-glass window in the church)
*Power Rangers ("My queen! I've..FAILED YOU!" "Make my monster GROW!")
Excellent movie!
