Zero's body became a red blur as he dashed rapidly to avoid the spray of fireballs. They flew over his head as he moved in on Fefnir - with a gun that huge, the guardian couldn't exactly run and gun. Which meant Zero could take advantage of how stationary he was while firing.

The moment there was a pause in Fefnir's attacks, Zero charged in. The larger reploid was probably charging for an even more powerful fireball, but that left a window of opportunity to interrupt him.

The Z-saber crackled as its blade became pure electricity, and he lunged at Fefnir with a stabbing strike.
