Guess wannabe space ninjas and their freaky-eyed bosses don't exactly count as arch-enemies.

Kai Leng doesn't even come close to filling the role for Saren. Sure, he is faster and stronger, but he doesn't have that "nemesis" element in him like Saren did. Saren was highly charismatic, a great leader, convincing the geth to work with him. Kai Leng's just some space ninja trying his hand at villainry.
