Since the Soldier has a Centurion veriant, I thought that it would be cool if the All-Star had some Roman representation, since the Gladiator in ancient Rome is all about sport, it fits the asthetic vibe for the All-Star, since the Chum Champion is loosely based on the Retiarius Gladiator in PvZ Heroes, it would be great to have more Heroes Characters ported in GW3, and to that extent maybe his weapon of choice can be a blaster with a trident and a net as design and fish as his ammunition, it can fit perfectly as a Toxic variant for the All star.
