How would you rewrite Piggard ?
For those who don't know, it's the nickname some people in this sub gave to the Pig King/King of Faubrey - Malty's perverted uncle.
In canon, I think he's just a misogynistic plot device to punish Malty - the beautiful woman being raped to death by an ugly old man really come off as Malty being punished because she's sexy above all else. His only characterization is that he's basically a stereotype about rapists : Ugly, threatening, doesn't bother to hide his intentions and animal-like.
Personally, I'd make him just as evil as in canon (or possible worse). Basically, I would rewrite him to be less ugly and to look like a jolly, almost affable old man at first, like Honest from Akame Ga Kill (here's what Honest looks like : Honest | Akame Ga Kill! Wiki | Fandom). My reasoning is this : Rapists IRL are actually not always as obvious to spot, they can look like normal people and most of them are acquainted with their victims. Plus, the reader/viewer would be subconsciously more encline to trust a grandfatherly man who vaguely looks like Santa Claus than a pig-like abomination, making the reveal that he's a depraved monster hit hard, almost like a betrayal !
In my retelling Piggard would also psychologically abuse and gaslight his preys as well - I find a stereotypical ugly monster with no depth besides "rape rape rape" less terrifying than a soft-spoken sadist who looks trustworthy and even safe, and minutes later is calmly whispering to his red-haired niece "I'm going to do a lot of interesting things to Melty once I'm done with you"
Also, I'd include Faubrey sooner in the story (by making people referencing the country/the Pig King in an offhand comment for instance)
What would you do if you had to rewrite Piggard guys ?
