Continuing where I left off yesterday here are the seven remaining special characters. The vast majority of which fight their battles in black armour. Is there just me who thinks there's a bit too much black armour in this book with the addition of Templars?
Shadow Captain Shrike
High Marshal Helbrecht
An interesting prospect with his bodyguard of servitors. Essentially the servitors simply act as ablative wounds for Grimaldus. Combined with It Will Not Die they may make Grimaldus tricky to shift but then he's probably better joined to a normal unit to make the most of him. A 6" Zealot bubble is no bad thing I suppose but again it's a combat boost which isn't something marines do especially well. Maybe I'm missing something with the Black Templars but unless the meta changes significantly I can't see a decent way to make the most of them. I'll happily be correct though as they were one of the front-runners for which chapter I'd like to collect before the codex hit.
The Emperor's Champion
That's it for the special characters then. With the possible exception of Tigurius and maybe Lysander, none of them particularly jump out as being must-haves. Part of the problem is the ability to build your own character with some of the relic weaponry. This has the advantage of not restricting you to a particular chapter.
