Stalker was released carded in the thirteenth series (1994) as part of the Battle Corps subset. The Battle Corps figures were numbered 1 through 13 - Stalker was number 9.
In 2002, Stalker was renamed "Sgt. Stalker". So while there are several names, there are a total of seventeen figures based on the character "Stalker".
In 2006, a Lonzo R. Wilkinson figure was released, showing Stalker from his years prior to G.I.Joe.
Accessories:
Stalker came with three different black guns, a black machete, a black missile launcher (spring loaded, actually fired), two black missiles, and a black figure stand.
Except for the missile launcher, all of Stalker's accessories came attached to one plastic "tree". The accessories were removed from the tree.

Variations:
There were two variants of the Stalker action figure. The first variant
has yellow highlights on the figure's chest and has the date stamp "MADE
IN INDONESIA." The second variant does not have the yellow highlights
but does have the inner leg bands painted. It has the date stamp "MADE
IN CHINA."
There are also two variants of the packaging. The earlier first variant featured the G.I.Joe logo horizontally at the top of the card. The filecard on the back of the packaging was the "standard" size. The later second variant featured the G.I.Joe logo vertically on the left side of the card and the filecard was reduced down to "baseball card" size.
Body Construction:
Stalker's body is entirely original - no parts were taken from other figures. None of his parts were ever used to create other figures.
