... we're making costumes, not ZOMG WEAPON LENGTH LAWLZ, no need to be a troll about it. technicaly Kirby is like 8 inches tall, but do u see kirby as 8 inches in the game? NO. why? cus it would not work out.
I'm 100% sure if they're gonna make the alternate costumes, they can make it so the mesh of the swords either aline, or just keep the same hit boxes, and if u know how to program/render 3D mesh, u should kno wat I'm tlaking about.
Hector doesn't need to look like them to have a suit for them, some ppl even suggested Ayra as a suit for Marth, and we all know Eliwood is like a paladin, Lyn is like a sword master and hector like a berserker, if u play the game u would know.
