Famous Evil thri-kreen?

I’m running a con game where the pcs are villians from across the worlds of d&d. All monor named characters. I’ve been looking for a named evil thri-kreen but I can’t seem to find any. Does anyone know of one from the lore?

Any evil half-giant NPCs are welcome as well.

Thanks.

Sorry mate, can’t find any… maybe the Great One? Probably an Avangion, but that’s your choice since there’s not much information on it. Half-giants… same, nothing.

Dragon’s Crown has Hamanu’s squad of “evil mirror pcs.”

Among them are

Chtek Ch’re, a NE genderless kreen fighter 10.

and

Ulreg the Strong, a ?E female half-giant gladiator 8.
