Well, you've certainly set yourself up for a very stompy fic.
Which isn't a bad thing, stomp fics can be oodles of fun in their own right. Throwing an SI into an AU is a nice touch by the way, and I want to ask how much Crack this story will have?
When the title mentioned Planetary Annihilation I was prepared for yet another Commander waking up somewhere and immediately saying 'Fuck it' and start up the metal tide of units.
I am pleasantly surprised by the fact this did not happen (yet. It's a PA fic, the tide of Popcorn is inevitable.)
I'm liking this a lot, one of the few MHA fics I've seen so far that has objectively shady family dealings.
I gotta ask though, did you take some inspiration from the 'El Tigre' cartoon that had a similar family dynamic?
