YMMV / Brennus

• Hilarious in Hindsight: One of the early Arc Villains is the Crimson Goblin - acknowledged in-universe as a blatant rip-off the The Green Goblin with a color switch. This was written five years before Go Down Swinging which introduced the Red Goblin as a canon Marvel character - specifically, Norman Osborn bonded to the Carnage symbiote. Admittedly, Crimson Goblin isn't nearly the same threat level.
