Benannt sind diese Grendels nach einem gefährlichen Riesenmonster aus der japanischen Mythologie. Wie bei den C3 Standard- und den Banshee Grendels steigert sich die Aggressivität der Orochi Grendels im Laufe des Heranwachsens um im Erwachsenenalter schließlich für Norns und Ettins lebensbedrohliche Züge anzunehmen. Orochi Grendels sind amphibisch.

Appearance: Orochi Grendels verwenden die Sprites der Banshee Grendels (Grendel-Slot B) und der Zwergbunt Grendels (Grendel-Slot M).

Farbgene: modifiziert, alterstufenkonstant

Description:

"The Orochi Grendels start out friendly and peaceful, creatures who prefer to play with toys then hit machinery. When childhood comes, however, they go after norns to hit when they are bored. Usually, they do not hit enough to kill the norn. Adolesence brings on an instinct to hit ettins, and the Orochi take on a smaller form that resembles what they will look like when adult. It is also the stage killing norns and ettins begins. At youth, a chemical reaction causes norns to make orochi angry. They hit norns when angry at this stage. Adulthood brings on the final hitting instinct (hit ettins when angry). They are at the most dangerous stage at this point. Fortunatly for norns and ettins, Orochi move slow." Grendel Man
