Fantastic Four Annual #3 (1965)

Reading a newspaper announcement of Reed Richards and Susan Storm's wedding day, Doctor Doom plots to ruin it by using his Emotion Charger to incite the entire super-villain community (whether or not foes of the Fantastic Four) to attack the ceremony. A crowd has gathered outside the Baxter Building, where the wedding is to take place, to watch the celebrity guests arrive. The onlookers include both Millie the Model and Patsy Walker. Nick Fury and S.H.I.E.L.D. are providing security for the wedding, and prevent a guest whom the Puppet Master is controlling from poisoning the Thing. While the Thing is considering whether to tell Reed about the incident, Mole Man and his subterranean Moloids attack from beneath the building. Professor X summons the X-Men to aid the Thing in warding them off. Meanwhile Reed, Sue and Johnny are attacked by the Red Ghost and his Super-Apes, until the latter are banished to another dimension by the newly arrived Doctor Strange. With the initial attacks defeated, Dr Doom increases the power inciting villains including the Mandarin, the Black Knight, Kang the Conqueror, the Awesome Android, and the Grey Gargoyle to attack. Whilst on his way to the wedding, Thor is attacked by the Super-Skrull. Daredevil spots Hydra agents attempting to collide a missile with the Baxter Building and succeeds in driving it off, dumping it into New York harbor: the missile's detonation destroys an attacking undersea force led by Attuma. The arriving Avengers, Captain America and Hawkeye battle the Cobra, the Executioner, the Enchantress, Mr Hyde and the Mad Thinker, with the help of Spider-Man. While Daredevil is being chased by the Black Knight, assistance from the X-Men is interrupted by the arrival of the Mandarin, Electro, the Unicorn, the Melter and the Beetle, whilst Quicksilver simultaneously battles the Human Top. These events rapidly culminate in an all-out battle between the heroes and villains, until Reed Richards is summoned to the Watcher's citadel, where he is given a device that will allow him to transport all the attackers away, with no memory of what has transpired. With the villains defeated, Reed and Sue are married. Outside, Stan Lee and Jack Kirby are turned away from the ceremony as they do not have invitations, and leave muttering dire threats of retribution.
