I don't mind the Glenda figure. I like it. Looks like we will get a retro Scarlett and a Flash sometime in the future.
Hasbro tried to release Glenda before, but ended up just making her a pilot Scarlett, probably cause they felt no one would know who Glenda was. I did make it into a Glenda though.
I plan to keep her though if it gets unlocked, and hopefully we do unlock it and the 3rd tier would be really good. However, she keeps saying as a callback to the Skystriker Haslab, makes me think the 3rd unlock really would be some version of Airborne as he is the co-pilot on the box.
I wouldn't be surprised if they made the base of an Airborne figure and called him something else or made it a generic trooper and then they can release the real Airborne to retail, or gave him a different color scheme.
