Captured on Monster Island and transported to an ARGENT laboratory in Millennium City only to be subesquently rescued by Professor Zack Zapperoni, Julius (also known as Dog of War) found himself learning to cope in an urban jungle.
With the Professor's help he was able to learn more of the City and the world. His education was swift due to the various brain surgeries he had undergone while in ARGENT's hands.
Deciding to remain and aid the Professor, Julius joined Science Heroes Against Felonious Threats; mainly acting as a bodyguard for the Professor but also carrying out missions where required.
Julius uses a device provided by Zapperoni to give him exceptional running speed, and also utilises his natural agility.
