Sinister Six


 * "Not our power, it was our plans that fucked us in the past. But together, now, we stand strong against the Spider and we can beat him together!"
 * ―Sandman

The Sinister Six is a constantly adapting group of mercenaries and thieves with different motives and views, but the thing that always stays is their equal hatred for Spider-Man

First Generation (Toomes's Team)
The Team was founded by Adrian Toomes, more notably known as the Vulture, who had been freed from prison. After realizing nobody would hire him, he formed the original teams to provide himself with an income

The team's downfall started when Rhino and superpowered thief Spot grew a conflict which led Toomes to kill Spot and replace him with Chameleon, the death hit the news drawing the attention of young Spider-Man. Peter was able to single handedly defeat the six but almost lost his life to Mac Gargan in a last minute attempt at an escape

Second Generation (Ock's Team)
The Second Generation begun with the lead of Doctor Otto Gunther Octavius who was later nicknamed Doctor Octopus by the colorful crimestopper and Daily Bugle, he had been fired and had his ideas stolen by Harry Osborn who began running Oscorp after the death of his father, Norman Osborn.

This led Otto to recruit several people to form a new generation, during his masterplan to deal with both Spidey and Harry he disposed anyone in his path, including Lady Stilt and Mysterio. This led Sandman to quit feeling unsure of his safety, Otto then sold him out to the authorities and he was later apprehended by such. Spider-Man later defeated the entire remaining six on the Oscorp building

Third Generation (Sandman's Team)
After escaping prison, Flint Marco started a new generation of the Sinister Six alongside some of Spider-Man's greatest threats so he could defeat him and the man who imprisoned him (Otto Octavius). His plans we're also foiled by Peter but the team mostly stuck together realizing how strong they we're together

Replacing Venom
After Otto Octavius escaped, he made a deal with the Sinister Six to make technology for them in secret. He didn't fully join until the Clone Conspiracy story arc which Venom quit in and moved to San Francisco.
