Kia has teamed up with DC Entertainment to build a series of Justice League-inspired custom cars for charity. The first five appeared late last year, and at the 2013 Chicago Auto Show, Kia unveiled the Superman Optima Hybrid. The Superman Optima is the sixth of eight planned Justice League cars being built to raise awareness of DC Entertainment's "We Can Be Heroes" campaign to help bring relief to people affected by drought and famine in the Horn of Africa.
