If Eddie had to have a permanent Symbiote, why couldn't they have kept him as Anti-Venom? That was his best form! Aside from being stronger then most Symbiotes, the Anti-Venom Symbiote had NONE of the weakness that they had and he could cure ANY illness. The second they killed off the Anti-Venom Symbiote I was pissed off majorly, Toxin is okay and yeah he is the strongest Symbiote so far as he was spawned from Carnage but it doesn't really make up for it the fact that Eddie might as well be a mix of Venom and Carnage now.
Funny because (spoilers) he calls himself Toxin but his latest design has him look like a red Venom. Wonder if he's finally exerting some sort of control over the symbiote and is back on his anti-symbiote crusade again.
