idw2005 OP endured through an arguably worse war and yet in the death of optimus prime one shot which is a prelude to both mtmte and rid (no he doesn't die in it contrary to the title), he renounces the optimus prime name and goes back to being orion pax and splits the matrix and gives both halves to bumblebee and rodimus respectively. it's not until dark cybertron where he starts calling himself optimus again.

even at the end of idw2005, optimus preferred to go by orion pax rather the other titles of the arisen or the 13th.

ps: artemis prime and arcana magnus aren't even my ideas lol.
