It’s a headcanon that's just in my head, but I picture Meltch Krakko (from the Maul book) as a massive man—like, even taller than Savage.
There’s nothing to suggest that; the book just describes him as an adult Mandalorian in full armor who is bigger than Maul (which, considering Maul was between 13 and 15 years old and malnourished—wasn't all that hard), implying an average-to-tall guy. Just a regular guy.
But in my head, the mental image of that scrawny Maul—or even when he's older, more lean and agile rather than heavily muscular— at a screaming match with this huge, fully armored, just as bulky and extremely dangerous Death Watch Mandalorian is hilarious.
He isn't the least bit afraid of the guy, and he’s so used to it—since Krakko already seemed like a giant when he was little—that he doesn't even notice or understand other people's reactions. Someone asks what species Krakko is, and he says "Human," and everyone goes, "Humans don't grow THAT MUCH!" And he just shrugs— Krakko did, what do you want him to say?
Also Savage getting outtowered by someone else, that someone being his brother teacher/father/bully, who will also scream at him at any moment if so confusing for him and makes things even funnier.
