Just because one has Eddie Brock's symbiote, it shouldn't make them "Venom". Venom is EDDIE and the Symbiote. Heck even the name Venom comes from Eddie's career working for "Venom spewing tabloids". Gargan should incorporate his Scorpion persona into like maybe have the suit produce a scorpion like tail and a Scorpion insignia on his chest, that's clearly a scorpion, though he might have that but its really hard to tell.
