[@Silverwind Blade]A quick question? Why allow the Pale rider if it has HADES unless the system was overhauled to just be a simple boost to performance. A reminder that the HADES system literally drives its pilot insane. Also unless I'm mistaken all the Pale Riders were destroyed.

There's enough ambiguity and wiggle room to allow for one Pale Rider (at least) to have survived from what I read about the mobile suit on the Gundam Wiki. And in discussion with Tate he's asked it to be equipped with EXAM instead of HADES, and I said 'sure' with the caveat that it'll come up as part of the story later, considering that EXAM is powered by [s]pure evil in a can[/s] the captive soul of a Newtype. 
I mean, I'm going to go with the idea that it's not common knowledge that's a thing, so our characters likely wouldn't be aware of that right away - which makes it an interesting plot point to deal with when it comes to light.
