Rome had an interesting naming convention where the more names you had the more powerful you were names were like inventory slots for accessories, they denoted who you were, where you were from, who in your family has done something cool, ect. They honestly operate a deliciously lot like how scientific names work.
Most Romans had two maybe three names, Romans from prestigious families or money usually had four. so like a noble might have personal name (nomen), family name (gens), famous ancestors name (patronimicus), clan name (cognomen), and if they've done something cool they'll have a nickname - whereas a common person probably just has nomen, gens and (if their family is from Italy) a cognomen
but you do run into an inflation problem
All to say that there was one emperor who's name was, I shit you not, "Lucius Aelius Aurelius Commodus Avustus Hercules Romanus Exsuperatorius Amazoniue Invictus Felix Pius"
"SuSianus Amongus" is the lowly provincial novice-homo Susianus from the heretofore unheard of and of little note, Amongus family
Lucius Aelius Aurelius Commodus Avustus Hercules Romanus Exsuperatorius Amazoniue Invictus Felix Pius looked at the fact that he had twelve names and that there are twelve months and decided why, might as well name each month after me
He was strangled in the bathhouse a few months later, in the month of Aurelius I believe
His predecessor would last less than a hundred days in office, the man who replaced that man literally bought the title of emperor at an auction (the price if you're curious was 30 years pay to each agent in the secret police)
He would last sixty days (good for him!)
man the "year of the five emperors" is so much more interesting than the year of the three emperor's or even the year of the four emperors.
