Borzel is a post X-Day Hyper-Zoanoid that appears only in the Guyver manga. This hulking creature is covered head-to-toe in shock-absorbent chitinous plates and the plates are covered in razor-sharp spines. Borzel's primary method of attack is to curl up into a ball and roll over the battlefield as a menacing wheel of death, shredding all enemies in its path.
A Borzel was seen defending Cronos HQ in Arizona when the base was attacked by Agito Makishima and his squad of Libertus.
