The roar sound effect sounds like this: https://www.dropbox.com/s/z5a8ff7ridnfqit/Roar%2015.wav?dl=0.

I've only heard it in the original Ben 10 series (2005 - 2008). The first time I heard it is in "And Then There Were 10", when the giant robot raises its head up when first landing on Earth. The second time is from "The Krakken", where it is heard 2 times. The first time is when the Krakken busts up through the docks to attack Jonah and his men who are making off with her eggs, and the second is near the end of the episode where the Krakken is about to eat Jonah before she is stopped by Ripjaws. The third time I heard it is from "Truth", where it is heard 3 times near the end of the episode. First, it plays quietly while Grey Matter is talking about controlling the escaped Null Void Guardian. Then, the second and third times are when Grey Matter is trying to fly the thing. The fourth and final time I heard it is from "Secrets of the Omnitrix", where Tetrax looks back at Ben and Gwen, surrounded by the prisoner aliens after having knocked out Sixsix. Is this a stock sound effect? If so, where is the link for it?
