Kori Blade

The Kori Blade is a large sword completely made from durable ice, forged and wielded by Sub Zero from the Mortal Kombat series.

Features
In the original timeline, the blade is a thick, long broadsword that simply spawned in the hands of Sub Zero, allowing him to slice his opponent up without it breaking. In the alternate timeline, however, Sub Zero wields a much small, weaker sword that breaks once it hits his opponent. However, by freezing the air around him into the shape of the blade, the ice swords are infinitely sufficient.
