I'm going over the traits that Eclipse got from Sun, vs the traits he got from Moon, and. Help me. I feel like there's a lot more than what I came up with
Anger and spite. Because think of how Moon used to be toward Sun, before he started changing
His intelligence. This one's a no brainer
His acting skills. Think about how Moon pretended to be Lunar a while ago during the first October Takeover, and it was convincing. Sun has attempted to act as well in different situations, but it was fairly obvious that it's not his strong suit
His knack for building and repairing things. Because we know Moon does these things pretty regularly
Any sort of home-ec skills (like cooking, sewing, cleaning, crocheting, knitting, house repairs, etc). Moon, for a while, couldn't cook to save his life. It's a skill he's still learning, while Sun seems to have a pretty good grasp on it. Sun, all around, is better at home-life sorts of things. Eclipse made it seem like being in a daycare attendant body automatically gives him these skills, but if that was the case, why isn't Moon better at those things?
The awkward "staring at someone I like through a window and breathing so hard that I fog it up" thing. Francis gave Eclipse a dream a while ago, in which he fell in love with every lady he saw. He stared at Ballora through her glass wall/window and was fogging it up. Sunny did the exact same thing recently with Roxas. Idk if Sun's done it with Roxanne (or if EAPS Sun has done it to Foxy), but there's a possibility that he might've
Being a magnet for dead children. Dazzle literally came out of the walls to be with people, and she almost immediately latched onto Sun. Eclipse also attracts dead kids. 3 of 4 are kinda stuck and can't really move on, from what I know, but like. Andrew probably could've passed on, but he hasn't. I'm pretty sure he's kinda sorta tethered himself to Eclipse, at this point
I've heard that Eclipse also got his charisma from Sun, but. Look at Sun. Look at me. Look at Sun again. I don't think charisma is something he has
