Would you be willing to answer a few brief questions about PlayStation Forums?
4. Pyramid head (big **bleep** weapon)
That's all I can think of as candidates...
how about a sentient sword that wields another sword?
pyramid head vs aya brea is the next rivals we need. they are perfect for eachother.
Capra Demon from Dark Souls fits the bill, he even has two of them big swords.
