The Base Figure is a Marvel Legends Abomination "Hulk" figure. The arms from the elbow down are the Build a Figure parts from a Onslaught figure. The head is from the BAF Brood piece. It has been drimmeled and sculpted to fit onto the body. The lower legs are from a Buzzing Beetle figure and the face tusks were taken from a ML Loki's helmet.
I felt the pieces fit together well making a impressive exoskeleton for this armored monstrosity. Anyone unfamiliar with an Umber Hulk from the Dungeons and Dragons Monster Manual, These 8' plus tall monsters are intelligent opponents. They usually dig to a point adjacent to a main corridor, then wait, peeking through a small crack they've made, until likely prey walks by. They will then spring out upon its startled victim.
