Benkei Hanawa features prominently in the film *Metal Fight Beyblade VS Taiyō Shakunetsu no Shinryakusha* as a core blader. He possesses a large build, short purple hair usually hidden beneath a white beanie decorated with a red bull's skull, and reddish-brown eyes. His attire consists of a red and black jacket, gray shorts, and black shoes. Benkei's personality blends toughness with deep kindness and fierce loyalty; he often masks his softer side to avoid seeming weak. He maintains an enthusiastic, determined spirit, especially during Beyblade battles, and shows a notable fondness for food, particularly burgers.

During the summer vacation setting, Benkei joins friends for beach activities and a Beyblade tournament. An early comedic moment sees him choking while asking for food and reacting badly to a beverage offered by Kenta Yumiya. He later competes in the tournament, battling Masamune Kadoya but ultimately losing the match.

When the antagonist Helios attacks the tournament venue, Benkei witnesses Gingka Hagane's defeat by Sol Blaze. He promptly joins other bladers in launching his Beyblade, Dark Bull, against Sol Blaze in a coordinated counterattack, though the effort fails. Later, finding Masamune and Ryutaro Fukami injured, Benkei helps transport them to safety. He then accompanies the group to confront Helios at his headquarters. During the battle, Benkei intervenes as Helios overwhelms Masamune, launching Dark Bull alongside Kenta and Yu's Beys to shield his ally. This intervention forces Helios to unleash his special move, Blaze Execution, which nearly destroys Dark Bull and the other Beys.

Benkei's actions consistently demonstrate his loyalty to friends and his willingness to confront major threats despite personal risk to himself and his Beyblade. His role aligns with his established traits from the *Beyblade: Metal Fusion* series, including his past as a former Face Hunters gang member and his subsequent growth into a supportive, protective figure.
