Dave Bautista: 'Guardians Of The Galaxy' Star -- Drax The Lunch Box Destroyer

Step aside Benicio Del Toro ... the real collector from "Guardians of the Galaxy" is Dave Bautista -- and he just copped a one of a kind treasure for his collection.

Fun fact ... Dave is an avid lunch box collector -- he's got around 100 -- so "GOTG" director James Gunn had a custom Drax box made for the former wrestling champ. The first of its kind.

Bautista didn't just receive ... he also gave custom WWE Championship belts to some of his co-stars like Chris Pratt and Zoe Saldana.
