Chimera Slug

The Chimera Slug is a Chapter 3 monster assaulting Illiasburg. Luka does not fight her; rather, she rapes a trio of human men before Luka seals her.

Monsterpedia Entry
''“A Chimeric Monster created by Promestein that is based on slime-like monsters to operate in specific environments. Improvements were added at a gene level to increase her activity in high and low temperature areas. The basic data her creation and tested provided appear to have been used by the Next Doll program.''

Her combat capabilities are not very high (of course still higher than a normal monster), but she was added to the invasion forces to acquire more experimental data.

''Able to change the shape of her own body at will to assist in adapting to various environments, it also enables her to change the shape, size and formation of her sexual organs freely. Using that special technique, she can easily force males to ejaculate at near will.”''
