Well, I promised you some pretty weird stuff.
These were simply 'rhino man' when I wrote them out on a sheet of A4, and they appeared in an adventure alongside triffids, the party having to help defeat the triffids so the rhino men could get back across a patch of land on the other side of a bridge to reclaim their tribelands. I was a kid, cut me some slack :)
I've since given them a name derived from Hindi, and rarely used them. But they're there, and one day I'll pull them out again.
Gainda manaav (Rhino Man)
by Cab Davidson
Stat Gainda manaav AC: 5 HD: 4* Movement Rate: 120(40) Attacks: 1 horn/1 weapon Damage: 2d4+2/weapon +2 Number Appearing: 1d4 (2d4) Save As: F4 Morale: 10 Treasure Type: Q (D) Intelligence: 7 Alignment: Neutral XP Value: 75 Gainda manaav are large (7 to 9) tall, grey humanoids, stockily built and with elongated, rhinoceros like, horned heads. They arent in any way evil, but they have a tendency to be both territorial and bad tempered. Their vegetarian habit necessitates claiming large areas of savannah or woodland as their own, and they defend such lands assertively. They form small family groups, for a while, and are happier in their own company than in that of others. They are capable of wielding weapons, and favour longer weapons with greater reach their great strength conferring a +2 bonus to hit and damage. Close in, they may also gore a target with their horn, and they can also charge to inflict double damage with their horns in the first round of combat.
Gainda manaav are fiercely territorial, and rarely accept the presence of humans or humanoids in their homelands for long. While typically individualistic they will band together to fight off invaders, or when their collective lands are threatened.
There are tales of larger, more wiked, furry gainda manaav, referred to as oonee gainda manaav, inhabiting the frozen wastes of the North. If true, they would likely be solitary creatures.
