Epithets for Makedonian Kings

[Centurio Nixalsverdrus]

Hi,

I'm thinking about how to call my deceased Basileus Alkyoneus, looking back from 10 years onward now. I decided to give each of my kings a sort of "cognomen", like it was in reality with Megas Alexandros, or Demetrios Poliorketes. So, Antigonos "Gonatas" because of the greaves, or because of him being from Gonnoi (that's what I read in wikipedia).

I thought about calling Alkyoneus

-"Asiatikos", because under his 16 years of reign Makedonia conquered most of Mikra Asia.

-"Rhodios", because he conquered Rhodos, quite important given the humiliation that suffered Demetrios Poliorketes. That conquest was only one of many though, and long before his kingship.

Were the Greek at all fond of calling their kings or generals names for beating a certain faction, like the Romans did so frequently ("Germanicus")?

Then, my current Basileus Perseus will most likely be known for the tightening of control of the Hellenes of the south. How about "Autokrator" (meaning Imperator)? I know it's historically an East Roman or Byzantine title.

Any ideas are welcome.
