“What was that?” asked Korrigan. The tightness of his voice betrayed his nervousness.
“Nothing,” muttered Dorlokk. “Stop jumping at every little sound. This is, after all,” he sneered, “the jungle.”
“There!” Korrigan hissed. “I heard it again!” He clutched at Dorlokk’s robe.
The mage swatted at Korrigan’s hand. “Unhand me, you child,” he commanded. “We paid good gold for this guide. He’ll tell us if there’s anything to worry about.”
Korrigan looked at the guide, a native tribesman who wore little more than a necklace of teeth and carried only a gourd of water and a crude spear. The man, his eyes wide with obvious fear, was looking back behind them. Behind them…and up. Up into the trees above.
Both Korrigan and Dorlokk whirled around, scanning the dense canopy over their heads.
“Come on,” said Dorlokk, his voice also sounding a bit tight. “The sooner we find this marker, the sooner we can–” His words died on his lips.
Korrigan turned to see what had silenced the mage, and he felt the blood drain from his face and the strength fade from his limbs.
Standing ahead of them in their path were a half-dozen man-shaped creatures. But their faces were those of great cats, and the menace was plain in their dark eyes. Tails twitched behind them, and their claw-like hands held weapons of steel…
No. Enc.: 1d6 (2d6)

These humanoid jaguars favor wooded or jungle settings. In their native environment they gain a +1 bonus to surprise and can track creatures on 1-4 on 1d6.
Due to their otherworldy nature, cat warriors gain a +2 bonus to saving throws vs. spells and magic and are completely immune to visual illusions.
Legend has it that these creatures must be killed nine times before they are permanently slain, but this may be nothing more than an old wives’ tale.
I imagine that there are various forms of Cat Warrior (tiger, lion, panther, etc.) with identical base numbers but modified special abilities.
I also suspect that classed Cat Warrior characters are possible for exceptional cases.
