Shrapnel's Henchmen

Shrapnel's are a group of criminals that appear in Hero, Book 1. They all wear military grade tactical gear and a majority of them were ski masks to hide their identity. It is possible they are mercenairies given that Shrapnel has a paramilitary background. Shrapnel had three or four henchmen back when he was a thief but was shown to have an entire army after he became a Supervillain and started working for Silas Prescott.
