I have checked the credits for the DLC since writing that post and it only credits Aevee Bee from Future Club as Story Support in Annie's story and is later credited for Writing/Story Support in Umbrella/Dahlia/Marie's stories, but I didn't see any other names, at least from the HVS or FC section of the DLC stories with express writing credits. Maybe they were further down. I know Kent Salvatore (with Christian Nutt) got numerous credits for pre-Annie story stuff. And of course know Alex was involved with the stories (although as you say, not involved in the writing per se).
But thank you for digging up that screencap. I'm really not privy to a lot of the more clandestine parts of the Skullgirls community (especially anything from the SGM side since I've never played it), so I not terribly familiar with Pen Stroke and MightyZug (Charley Price) beyond them being HVS devs. But that's good info, regardless.
A lot of the writing being team-produced or at least team-reviewed tracks, and that's what I've basically suspected. Individual writers get put in-charge of the brunt of a story and then it gets passed around and reviewed, edited, shored up and so on. There's probably a lot of lore checking behind the scenes and then some larger lore changes (such as the decision to confirm Franz was alive with his headless design which we knew previously wasn't necessarily canon). It's interesting. And it probably helps the stories keep some level of consistency even if, as you say, one could tell that there are some different styles at play.
Hard to say about Aeon's design. I could understand not taking the Robo-Fortune Story panel at face value, but it's also one of the two cases of Khronos' face being visible at all. At any rate, that drawing in particular does have some noteworthy/interesting details beyond two-headed Khronos, like Venus's boot having a winking face (which is a detail
that's shown up on occasion in Alex's drawings, but never in-game). Makes me want to see Aeon's model/design sheet.
