I am trying to make a team and need a list of all figs who were members of the sinister six. Thanks in advance.

I'm guessing a bit here, but wasn't the original Sinister Six composed of Doc Oc, Sandman, Electro, Kraven, Mysterio, and Vulture?

right on the money with that guess.

correct, & the 2nd Sinister 6 had Hobgoblin in it instead of Kraven. Was there a 3rd Sin. 6?

There have been multiple incarnations of the Sinister Six, but in one of my few comics the members are Sandman, Mysterio, Vulture, Kraven, Electro, and Venom.

THERE IS ONLY ONE TRUE SINISTER 6, AND THATS TGHE ORIGINALS:
ELECTRO
VULTURE
DOC OCK
KRAVEN
SANDMAN
MYSTERIO

ANYTHING ELSE IS A CHEAP SUBSTITUTE.....AND THAT INCLUDES THE SYNDICATE

Trying to remember, it was:

Doc Ock
Electro (We really need his Clix)
Sandman
Hobgoblin
Mysterio (Another great villian for Clix)
Vulture

Nevermind. Geez, four posts in the time it took me to type mine.

Doh', yes, mine was the Return, I forgot Hobgoblin replaced Kraven.

But one thing I thought, I didn't think Venom ever went along with the Sinister Six. I remember a time when Doc Ock tried to recruit him but instead Venom fought them all and defeated them. Of course, I could be wrong, my memory was already foggy of the original.

Bad Marvel Zombie, Bad, Bad (while ramming head against wall).

You want the entire roster history of the various 'Sinister' teams? Okay, here we go:
Sinister Six I - (Amazing Spider-Man Annual #1):
Dr. Octopus, Mysterio, Vulture, Electro, Sandman, Kraven

Sinister Six II - (Amazing Spider-Man #334-339, Spider-Man #18-23):
Dr. Octopus, Mysterio, Vulture, Electro, Sandman, Hobgoblin II

Sinister Seven - (Spider-Man Unlimited #9):
Mysterio, Scorpia, Vulture, Electro, Shocker, Hobgoblin II, Beetle

Sinister Six III - (Amazing Spider-Man vol.2 #12, Peter Parker: Spider-Man vol.2 #12):
Venom*, Mysterio II, Vulture, Electro, Sandmand, Kraven II

Sinister Syndicate I - (Amazing Spider-Man #280-281):
Beetle, Rhino, Hydro-Man, Speed Demon, Boomerang

Sinister Syndicate II - (Deadly Foes of Spider-Man #1-4, Web of Spider-Man Annual #8):
Beetle, Rhino, Blacklash, Speed Demon, Hydro-Man, Constrictor

Sinister Syndicate III - (Spider-Man Unlimited #12):
Beetle, Scorpia, Boomerang, Shocker, Jack O'Lantern

* - Venom was a member of the team for only a few pages. He didn't join in the first issue of the teams appearance, and was only a member for a short portion of the second comic before he was kicked off of the team by its leader, Sandman. Venom never was much of a team player ...

Mysterio, Dr Octopus, Sandman, Electro, Kraven the Hunter, and Vulture.

I think that was the original six.

Another incarnation of them was Mysterio, Doc Ock, Sandman, Scorpion, Kraven, and Vulture.

Actually, Scorpion has never been a member of the team. That's a common misconception.

according to the cartoon, the sisnister six was, I believe, Chameloen, Dr. Octopus, Mysterio, Shocker, Rhino, Scorpion, & later on Vulture replaced Mysterio I believe.

Great that mean that all these clix can arguably be used:
Dr. Octopus
Vulture
Sandman
Kraven
Hobgoblin
Scorpion (close enough to scorpia, right?)
Venom
Rhino
Boomerang
Constrictor

So why are Calypso, Kingpin, Bullseye, Whirlwind, etc. in the Sinister Syndicate in clix?

They've all fought Spidey at one moot point, or another, I think. Oh, & you've forgotten Mr.Hyde, & Blizzard, & maybe some others.
