i would have two:
1. The Heartless Blade: looks like the heartless symbol, the top of the heart will be the blade, double-sided, the handle is the cross looking thing at the end. Black with red out line and a red handle.
Str: 20 against Heartless, 10 against Nobodys
Mag: 20 against Heartless, 10 against Nobodys
(both 15 in a neutral state)
2. The Nobody Blade: looks like the Nobody symbol, the cross would be the handle and heart would be a double-sided blade, of course it would be silver.
Str: 20 against Nobodys, 10 against Heartless
Mag: 20 against Nobodys, 10 against Heartless
(both 15 in a neutral state)
Dual equipped for the Kingdom Hearts Drive Form (uses power of KH)
