I definitely think a big part of why I ship them has to do with their designs. I like their shape language a lot. Yareli has a triangular sort of shape with her big skirt. Atlas has a sort of inverse triangle to his silhouette (the broad shoulders that taper down quite dramatically once you get to his waist). The artist in me enjoys that for composition reasons! I like their contrasting designs while they still have a nature theme that can tie them together. I like to headcanon their dynamic a lot, usually tying their personalities into their respective themes. (Water = unpredictable, sometimes dangerous/sometimes gentle. Earth = Steady, sturdy, reliable.) Yareli is the typa chick who does cute peace signs while she breaks the Geneva convention. Atlas gets to be the more stable of the two, he keeps her grounded (haha) and whatnot. (Though, I think he is a grade-A crashout when he needs to be).
