Aha, I knew there'd be a MOC thread somewhere. So here's the Defender:
Made out of the current TIE Fighter, the 2010 TIE Defender, and a bunch of random spares (and some of those newish 1x1 brackets I pulled out of the microfighter T-16 and advent calendar A-Wing, because I needed them to hold the wingtips together and those were the only ones I could find). It's not accurate to most of the art I could find of the TIE-D, or how they appeared in Rebels, but I was going for how I remember them being back in the old TIE Fighter game where I fell in love with them (mainly because the tractor beam made chasing down those damned TIE-As a breeze), where I'm pretty sure all the warhead launchers were packed into the body rather than the wings, and the pylons didn't flare out around the base (not sure those are all entirely legal, there's a few pretty stressed parts stuck in there holding all that forward weight of the wings in place). Plus a custom pilot, because the only reason I went through all those campaigns as Maarek Stele was that I didn't have a choice.
