Also the aesthetic here is much more French Freedom Fighter than a captain of the guard which I feel suits him better!
Aurelien ‘Antoine’ Montague D’Coolette, the son of a celebrated war general and formerly betrothed to Princess Solaris Concordia Acanthus ‘Sally Acorn’ as a child, is the team’s self-proclaimed Master Of The Blade (And I say ‘blade, not ‘sword’ because he’s packing half a dozen knives on him at any point of time like a coyote Machete. The fun part is guessing which ones are for kitchenwork and which are for shanking) though a lot of his bravado ties back to a childhood lived in the shadow of his father who pushed him to become a royal cadet and be ‘brave’ when he showed ‘softer’ tendencies ie. cooking and the arts.
So when he’s got front seats to Robotnik’s bloody coup and his traitor father attempts to use him to betray the Princess, he makes the split second decision to be brave for Sally instead of his father, who now terrifies him (and is who gave him his lip scar)
As much as he adores Sally who he essentially grows up with, he comes to realise that she has no romantic interest in him, and in making it clear that their friendship has always been the greatest gift she could give him, encourages her to put duty aside and follow her heart in this regard. (They’re still very BFFs—he cooks for her, she helps him with his hair, they both trade chaste forehead/cheek/paw kisses on the regular)
He and Sonic have a bit of an argumentative bash-brothers relationship, and he likes to think that he has more sense than this feral gremlin of a hedgehog but really, when they’re busting heads together they both have ONE brain cell, and Sally’s holding it.
Having helped care for a disabled war veteran uncle (who was more of a father to him than his own father was) as a child, he’s the first on the team who actually has an inkling of an idea on how to help Bunna-Marie ‘Bunnie’ Rabbot through her trauma and acclimatise to her cyborg limbs (he ends up building a little physio-rehab set for her and it’s in the banter of these sessions that they come to understand each other better beyond ‘uncouth lapine’ and ‘pretentious pup’)
