Using his ability to morph his own flesh, Number 6 transforms into a more physically powerful four-eyed monster with a tail for propulsion and balance adjustment, with a body that optimizes respiration, visual input, muscle, and bone structures to allow for a state where he can permanently accelerate. Just like with Crawler Style, this was named after and inspired by The Crawler.
Number 6 can modify and restructure his body even further to grow two extra arms on his back, as well as lumps loaded with explosive substances to use them as bombs. While in this transformed state, Number 6 can reconfigure himself into "Sniper Style" for an alternative method of attack.
In this state, Number 6 also possesses a hard exoskeleton covering his entire body.
