Planet Core

The giant parasite looked like an albino fangless snake, it wriggled and writhed as it charged its head towards us, screeching in a loud deafening noise.

X and Y flew forward, heading to the serpent, their weapons ready. Y's swords were primed and hot as the spinning sawtooth on them whirred awaiting carnage.

Since Y was of a higher grade, and more sophistically built, he was far faster and arrived at the head of the parasite first.

The two-kilometer-long parasite opened its mouth showing a circular jaw of sharp teeth that aimed to consume Y whole. Only he moved one of his legs to the side, and exploded the thruster on the sole of his foot to the max, pushing him aside in a spiraling motion, dodging the chomp.

He then pulled all four of his swords and began spiraling around the parasite as if he was a Beyblade, spinning around the parasite several times from head to tail, leaving a splatter of gushing blood exploding out from its tender flesh.
