Hercules

Pitch black and shaped after a supercar, Hercules belongs to Toshinori Yagi and runs on an artificial intelligence of its own. Its toughness is not for show: a grenade going off right beside it left the frame intact, and Toshinori remarked that most vehicles would have been scattered across the road.

Its name comes from the Roman deity associated with strength and heroism, and the silhouette invites comparison to the Batmobile. Behind the voice sits a small piece of casting history. At Kohei Horikoshi's suggestion, Mirai Shida, who voices Melissa Shield in Japanese, speaks for the car's intelligence, and the performance was steered to echo Melissa, given how much of Toshinori's late-series support gear traces back to her. Erica Mendez, Melissa's English actress, took the same double duty in the dub.

Beyond raw armor, the car works as a mobile base. It can put out a range of support items, and it carries cameras along with the means to broadcast what they capture.

Its intelligence is not sealed inside the chassis either. Hercules links to the Armored All Might, the equipment Toshinori brings to his final confrontation with All For One, making the two systems one operation rather than two.

Toshinori drives it while trailing Izuku Midoriya during the hunt for Tomura Shigaraki. Two villains ambushed him one rainy night with a grenade, and the car absorbed the blast without harm reaching him. A second attempt did more: propelled spears punched through the armored glass, and Toshinori had to bail out at speed and roll clear while the car careened into a wall. The wreck proved survivable, and Hercules was back on the road afterward.

Its end comes in the fight against All For One, where it throws itself between Toshinori and a devastating strike and is destroyed along with the rest of the suit. Eight years past the Final War it exists again, rebuilt and still his, and he uses it to bring Izuku back to his old Class 1-A classmates after handing over the armored suit that returns him to heroics.
