In the fusion au Ace would never doubt that he is loved/wanted... (which makes losing Sabo so much worse) Luce would be a chaotic/caring fusion, Sabo+Ace (Sace? Aabo?) ultimate big bro meets tricky bastard, Luffy+Sabo?(Lubo?Labo?Saffy?Saby?) Two words: FERAL BASTARD. ASL fusion would just call themself ASL, and probably be semi nonverbal because they don't NEED to talk, they are so content BEING that they don't need words unless spoken to...
Ace+Sabo: Asa (cue Luffy giggling childishly when he meets Aisa in Skypeia and tells her that his big brothers’ fusion had the same name as her) Sabo+Luffy: Saru (since Luffy’s name is pronounced Ruffy in japanese, and it sounds better than salu)
Yes to all of those (i’m wheezing at feral bastard, because you’re so fucking right). like on their own? sabo is the responsible big brother who usually keeps the other two in check. and luffy is chaotic but ineffectual and easily distracted by both his brothers. but put the two of them together? they get so much worse. it’s the exact reason that ace never lets the two of them fuse without him, if he can help it. they can’t afford the amount of destruction Saru causes every time he comes back lmfao.
ASL being semi nonverbal is so true though and I never thought about it??? Like, especially after the brothers move out of Dadan’s place, the only other people they hang out with on a regular basis are each other, and if they’re fused, there really is no other reason to talk.
After marineford in this au, i do think that the straw hat pirates still do the two year separation to train, so during that time luffy drops off the face of the earth, and sabo searches out the remains of the whitebeard pirates (what if they reform as the Phoenix pirates under Marco? that would be really cute, I think. not all of them would stay, but the other commanders, at least, would definitely join up).
when Sabo sees Ace in person for the first time in almost ten years, he throws himself into his brother’s arms, and when Asa blinks open his eyes for the first time in too too long, he’s so torn up that he disappears into his room for hours, refusing to speak to anyone else. he just sits there, alternating between happy tears, tears of grief, and manic laughter. he just doesn’t know how to feel. he lies in bed, thinking about how sabo had grown up in the revolutionary army. and the part of him that’s Ace is just so happy that his brother grew up safe and loved and surrounded by kind people. asa thinks about ace and luffy’s childhood together, and sabo mourns the fact that his supposed death had put them through so much grief. he mourns the fact that he had missed out on so many years with them. but he’s also so so grateful that he had lived to be reunited with them, and that he was able to see the memories of those days in asa’s mind.
ace knows when the straw hat pirates are supposed to regroup at the sabaody archipelago, so he makes sabo promise to meet him there in two years so that asa can surprise luffy,
sabo wouldn’t miss it for the world.
