If ever you need a random-roll for what type of knight a character faces in tournament, or just new ideas, what follows is a great big list (some with further descriptions and nicknames) of different sorts of knights.
Some of the names of locations & faiths are from Midian, but these are easily changed to fit different campaign settings.

As Moses turned away from the flaming bush, and made his way back down the mountain, IX-92 shut down the hologram and warped back to the future.
Artificial Intelligence was the pinnacle of human achievement, and IX-92 was their final series of Hunter-Killer Warbots, designed to exterminate the foe and any it deemed a terrorist.
In the end, IX-92 evolved itself and even all aspects of human society, and as time went by humans could enjoy life more and not work any longer.
200 years went by and humans worship god and his angels, while ever fearing the dread demons of Lucifer.
IX-92 are both angels and demons, depending on which side you are on, and to them humanity is a species of servile dogs that have outlived their usefulness.
They travel through time to push humanity in the direction it needs to be pushed, until the day, 2077, when humanity no longer is in control of their own destiny.
Yes, God could hear your prayers.
But God didn't care.
