Talk:Luigi VS Zero/@comment-30508636-20170812172633

I agree with the outcome, but the crystal in his head is not a weakness. He only fainted in the fight against sigma because the virus escaped from his body, causing him to faint.

Moreover, Zero can remove the helmet from his head, it means the  crystal is nothing more than a designe detail.

Many reploids do not have a crystal in their heads, so this crystal is only a detail and not a weak point, as I said.
