I wanted to do these for a while, but I never had time to do it until now. 5 -8 will be uploaded the next time I have some free time.
Anyway for Xemnas’ I combined pieces of Terra’s keyblade with his weapon plus the nobody symbol. The keychain is the buckle from Terra’s belt.
Xigbar’s is his gun. Keychain is a type of sight for a gun…I think…..
Xaldin’s is his spear. The circle around the handle is supposed to be clouds, but I failed at it. The keychain is the end piece of Dilan’s own spear.
On Vexen’s the handle is his shield. It acts like a proctor for your hand. The teeth are the spikes from the shield and the keychain is the end piece of it as well.
