PR Speculation: Broodwing was a member of Squid Inc. in selling weapons. Opportunistic as ever, he made off with all the company's assets after the Cosmic Fury Rangers destroyed them.
In fact, I'd bet that Emperor Grumm was one of their best clients until Zedd got their attention.
Stiiiiiill kinda wish one of their generals turned out to be Morgana in disguise in order to be deaged by Grumm. An after credits scene in the finale as all.
