Name: Spear of Tlahuizcalpantecuhtli
Origin: Toaru Majutsu no Index
Type: Knife/Spear blade
Powers and Abilities: Laser beams that disarm targets or destroy matter
Destructive Capacity: Large building level+ (but it ignores most conventional forms of durability so it should be to kill characters with significantly higher durability)
Wielder(s): Etzali
Material or Element: Obsidian
Needed Prerequisite for Use: The ability to use magic
Notable Attacks/Techniques or Alternate Forms:

- Reflecting The Light of Venus: The spear reflects the light from Venus to disarm or kill his opponent (Basically it forces the target to be dismantled). Etzali used this weapon to quickly destroy a large parking garage. This weapon has two weaknesses though. First, it can only shoot at one target. The original spear had enough power to annihilate all humanity with a careless shot. As such this limitation is very justified. Second, in order for the weapon to work the light of Venus must be reflected on the blade. In other words the Spear of Tlahuizcalpantecuhtli is close to useless indoors.
