Zekrom is a bipedal Pokémon of dragon- and dinosaur-like basis. Zekrom is mainly a shade of dark gray, with darker patches on various portions of its body. It has red eyes (although in some scenes its eyes are depicted as having white irises and red sclera) and a small horn-like protrusion on the tip of its snout, with its head sporting a plume tipped with light-blue coloration. At the base of its neck is a black, stud-like feature, and atop its shoulders are similar, larger features resembling armour padding. The bases of its wings also have such padding, and a fanned, splayed, seemingly webbed shape with a small "wing-spike" on one edge. The lower length of Zekrom's arms extenuate into splayed, seemingly webbed, somewhat baseball-mitt-like formations, with three-clawed, dark-colored hands on the undersides. The front portion of Zekrom's waist is black-colored, with its belly and thighs having thin striations down their length. Its knees are black, as are the foremost parts of its three-clawed feet and spiked heels. Zekrom's tail consists of large, round, conical and spiked formation, likened to an electricity generator, with a black inner portion and bands on the tip of the outside portion.
