This gentleman did not start out as a standard hero, but rather as a Standard bearer.
He started off life as:
At the time I wasnt interested in the Herald for my 30k faction, and I wasn't doing a 40k army back then either.
So using the 40k Ultramrines upgrade kit, and a very old Chaos Power Axe, I convert him (very minimal work here) into a Legion Praetor / Centurion.
And I threw a Legate Axe on him for Ap2.
Thankfully that all works to allow him to be a Lieutenant or Captain in my 40k army.. now just for some squad markings.
