the Symbiote had a nifty little family, most were made just to make money and were promptly killed off.
((these are the suit's not the suit's and the host's))
Venom
Carnage
Female Symbiote((Scream))
Carl's Symbiote((didnt name Symbiote))
Riot
Lasher
Purple Symbiote((was called shriek occasionally, but went nameless due to the fact there is already a "Shriek"😉)
the later 4 combined to form Hybrid, nothing special about them. Scream has appeared a few times and wasnt a bad character but the rest were pretty generic and pointless
Either:
Franklyn richards (Susan storm, Reed richards, johnny storm)
Magneto (polaris, quicksilver, scarlet witch)
Jean Gray (Scott Summers, Rachel Summers, X-man, Cable, Stryfe {cable clone}, Madelyne Pryor (jean grey clone), Corsair)
Psylocke (captain britain, jamie braddock)
Cant think of many other large marvel families, with most family members having super powers.
Malkavian, don't forget that Devil guy, Azazel, who is Nightcrawler's father, and the fact that he's got a bunch of other demonic kids running around.
Eleveninches, Magneto has more super-powered extended family. Crystal of the Inhumans was married to Quicksilver, and the Vision of the Avengers was married to the Scarlet Witch.
