Weapon. I mean it.

Sapphire weapon, ah, whatever...
Diamond weapon, pretty cool, i'd say.
Ultimate weapon, damn weak and cowardly, but COOOOOOOOOOOOLLL........
Ruby weapon, what can i say? kills everything in contact.
Emerald weapon, dont need to say anything.

this is off the subject, but if you go to www.geocities.com/cronosergerulz which is a music video place, you can also download a made-up story of Aftermath of Meteor, which includes the Mako Weapon (hahahahahahaha!)
