Stripe

Stripe is a creature found in the Big Empty in the Fallout: New Vegas add-on Old World Blues.

Background
Stripe is a Wild Wasteland encounter of a miniature deathclaw found in Higgs Village inside of Gabe's doghouse. In front of Gabe's doghouse is a "chicken" leg and Gabe's bowl, a unique dog bowl. Gabe's bowl can be brought back to Dr. Borous to complete the quest A Brain's Best Friend.

Biology
Same strength and attack power as a "Legendary Deathclaw", it can be safely assumed that Dr. Borous created him as either an intended pet or a stealthy weapon.

Gameplay attributes
Despite his small size, he is quite powerful. Having the same amount of HP as a Legendary Deathclaw, he may kill players who are caught off guard. Considering this and that his appearance is similar to that of a legendary deathclaw, he is likely just a scaled down legendary. However, Stripe will only pursue the player as far as the sidewalk before retreating back to the doghouse.

Appearances
Stripe appears only in the Fallout: New Vegas add-on, Old World Blues.

Behind the scenes
Stripe may be a reference to the lead antagonist in the film Gremlins. This is likely due to the somewhat similar appearance of a "miniature deathclaw" to a gremlin, and the fact that Stripe is a wild wasteland encounter.
