A streetwise New Yorker and the team's tunnel-clearing EOD specialist, trained to crawl into the dark places no one else will and defuse whatever is waiting. Visually modeled on writer Larry Hama himself.
Tunnel Rat is a G.I. Joe team operative in the A Real American Hero line. First released as a Hasbro carded action figure in 1987, with 3 distinct figure versions produced across the 1982 to 1994 vintage run.
Tunnel Rat 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.
