These beasts are mutated strains of three different species of buffalo: The African buffalo, the Asian water buffalo and the American bison. Like their brahmin kin, they have mutated into having two heads, though with relatively fewer deformities that the former.
Brahmiluffs are brahmin-like creatures mutated from African buffalo, Asian water buffalo and American bison. They feature the same build of the body with two heads. There are some main differences between the two. The most noticeable are the horns. Brahmiluffs have larger and more prominent horns. Their hide seems to be less mangled and more smooth, being far less disfigured by radiation.
Their ears are bigger and point downwards. Their skin color seems to be a lot darker than brahmin. They also don't have an udder, whereas the brahmin does.
Now tamed, these brahmiluff take the role of pack brahmin, carrying heavy loads in caravans. These are much weaker than standard bramiluffs and pose less of a threat.
Mutated by post-War radiation, these African buffalo are similar to the docile brahmin they are named after. These creatures show less damage from radiation and are generally healthier looking than their counterparts.
The brahmiluff shorthorn appears to be a mutated form of the American bison. Much like brahmin, they have grown a second head. They also seem to have albinism due to how light their fur is. Regardless, shorthorns are as healthy as their counterparts.
The brahmiluff longhorn appears to be a mutated Asian water buffalo. They differ very little from standard brahmiluff aside from their much longer horns.
