I signed both petitions mentioned in this topic.
Possible alternate names:
Xemnas:Energy Blades
Xigbar:*currently no idea*
Xaldin:Tornado Lances
Vexen:Frozen Shield
Lexaeus:maybe Earth Hammer
Zexion:Mysterious Tome(It kinda fits, actually)
Saix:Lunar Sword
Axel:Flaming Chakram
Demyx:Sitar of Aquatics
Luxord sad I don't have anything short and sweet for him. the best I can think of is Giant Playing Cards. That's not really interesting.)
Marluxia:Rose Scythe
Larxene:Thunder/Electric Daggers
Roxas:Light and Dark G-Blades
And that's what I have. Let me know if you like any of these, or if you have an idea for Xigbar's.
