Blood Gavial is a non-playable race in Tactics Ogre: Let Us Cling Together. They are described as "a variety of lizardman with blood-red skin. Its violence is remarkable, even toward its own kind." These lizardman variants always have "Blood Gavial" as a class and are typically found in the lower levels of the Palace of the Dead.
"Gavial" is an alternate name for the "Gharial," a critically-endangered, very large Indian crocodilian.
