Both the Marvel Database Wikia and the official Marvel Wiki agree that the Basilisk was killed by Scourge, but Wikipedia says that he was resurrected by the Hood to be sent after the Punisher.
Whatever. I just liked him when he first appeared in Marvel Team-Up #16 and went up against Spider-Man and Captain Mar-vell. Maybe it was the awesome Gil Kane art. Maybe it was that I appreciated a time (now long forgotten) when creators gleefully created new opponents all the time rather than going through the old vaults to see what characters could be revamped or revisited. Anyway, Basilisk deserved better than he got.
comicbook db has an appearance listing.
