You may want to arrange it so that the self-destruct ability will take out some of these items.
This is a lot like the drow-items-turn-to-dust-in-the-sun business. They make the encounter much more deadly and reduce the reward for overcoming him; I, and
SKR, recommend against it.
It may be a defining characteristic of the Predator, but I'd get rid of any Death Throes/Circlet of Blasting business you may throw at the PCs.
I'd make the class a straight Ranger, or Ranger/Barbarian. At least 5 levels of Ranger so he can get that second Favored Enemy. Maybe make one of them esoteric like FE: (Aberrations), so he can have Nagas and Mind Flayer sculls around and about.
Brachiation feat from Complete Adventurer, so he can jump from tree to tree.
Track feat, if you don't go Ranger.
Maybe the Run or the Dash feat, since his size belied his quickness.
Focus on the physical skills: Hiding, Move Silently, Survival, Spot, Listen, Climb, Jump, Heal, and probably Profession: Taxidermist, or Craft: Scrimshaw.
For weapons: Adamantine Net, Returning Chakram, Wounding Shortspear, Adamantine Claw Bracers. (Yeah, I know the net can't be adamantine because it's made of rope, but you might could bend the rule a bit here for the predator.)
Other gear: Healer's Kit, Chrugeon Artisan Kit, Acid vials, Fishnet Stockings of Awesome.
Why not give him a Spelljammer ship while you're at it? Make it something that the PCs would be able to use after
a lot of downtime research (like maybe when the arcanist of the group reaches level 15 or so). That won't unbalance the party since they'd be able to
Teleport anywhere they want by that point. But it would still be cool, eh?
