| This is starting to sound like a bad comic book plot|
This character is non-canon to Spider-Man: The Animated Series.
Montana was a member of the Enforcers.
In the comics
Jackson Brice was born in Bozeman, Montana. Along with Fancy Dan and Ox, he was a founding member of the Enforcers. He has great proficiency with a lasso. As a member of the Enforcers, he first came into conflict with Spider-Man when they were employed by the Big Man and next when they were hired by the Green Goblin. They also teamed up with Sandman to kidnap the Human Torch, but they were defeated when Spider-Man freed the young hero.
In the television series, The Spectacular Spider-Man, Montana was a member of the Enforcers. Hammerhead later gave Montana a costume and a pair of Vibro-Shock Gauntlets and became Shocker.
