It takes a mighty weird person to walk into a cloud of toxic gas wearing a protective suit built by the lowest bidder. Airtight does it gladly. "An unreformed practical joker, but when the bad guys start playing dirty it's old Airtight who suits up and wades into the thick of it."
Airtight is a G.I. Joe team operative in the A Real American Hero line. First released as a Hasbro carded action figure in 1985, with 1 distinct figure version produced across the 1982 to 1994 vintage run.
Airtight did not appear by name in the Sunbow or DiC cartoon series synopses. Original Hasbro file-card lore and Marvel ARAH comics appearances are the primary characterization sources.
