Lei Heng is standing at about seven chi, with a purplish face and a string of whiskers on his face. He possesses immense strength and excels in martial arts. He is nicknamed "Winged Tiger" because he could leap across a body of water several metres wide and jump over high walls with ease. Lei Heng is one of the leaders of the Liangshan infantry. At last, during the campaign against the rebel leader Fang La, he is slain in battle by the enemy general Si Xingfang.
