That was kind of what i was aiming for without just using the standard lorcia segmenta "oh heres a legionary look". One of my gangs for Gangs of Rome is called "The College of Mithras" they are a gang made up of ex-legionaries, led by an Ex-Centurion Titus-Decimus-Longinus known simply as "The Centurion". I have little back stories for them all but most were either invalided out or dishonorably discharged for misconduct or criminal activity.
The one in white is called Julius-Carius-Maximus, known as "Hippocrates" and was a medicus, he was discharged after 4 years with the 13th legion, nobody knows why.
The gang is 10 strong so far its members are;
"The Centurion" - ex-centurion
"Hippocrates" - ex-medicus
"Castus" - ex-legionary
"Felix" - ex-legionary
"Cato" - ex-legionary
"Pulcho" - escaped slave (the one holding the head up)
"Apollo" - Greek actor (archer)
"Narcissus" - escaped slave (slinger)
"Aurochs" - ex-batavian auxilliary
"Arminius" - ex-german auxilliary
I have a few photos of them actually
