Best melee class for an Ilithid NPC

This Ilithid npc is a big muscular man who uses sabers, and sometimes his own hands… he manifests nightmares and fear into his attacks to deal psychic damage (this part is homebrew) he is a leader of a radical and violent group of rebels, who want to do the right thing by the wrong means…

I thought about him being an Echo Knight because its cool asf… also thought psi-knight because se often uses telekinesis to wield his sabers, or deflect attacks… The telekinesis part is because of his Ilithid nature, so I thought it didn’t need to be a psi knight to do these things

I mainly want an intimidating warrior who can stike fear with looks alone, and can be as fearsome in battle, channeling nightmares into his attacks… any tips for his class?
