Leizhenzi

Lei Zhenzi is Yun Zhongzi's disciple and a young boy who can magically transform into a larger bird-man at will. He is considered the mascot character of the Fengshen Yanyi series.

In the English adaption of Mystic Heroes, he is known as Ariel and can be directed in the game's Mission Mode.

Role in Games
Soon after acquiring Wei Hu, Taigong Wang's party continue their march towards West Qi. A violent lightning storm suddenly interrupts their journey. The mystic Yun Zhongzi descends from the heavens and apologizes for causing the stir. He informs the leader of the party that he is present on Yuanshi Tianzun's behest. Offering his own student to assist the young taoist, the elder master calls Lei Zhenzi over. Though Taigong Wang is surprised to see a boy with wings, Ne Zha is unimpressed by the "brat" and tries to start a fight. In response, Lei Zhenzi morphs into his taller bird form to startle the mystical boy. Witnessing the boy's ability and thanking Yun Zhongzi, Taigong Wang agrees to the generous offer and accepts Lei Zhenzi as a member.

After the final battle, he returns to his master and is accompanied by Wei Hu. He also makes a small appearance at Kunlun Mountain with his master in Magical Fengshen, cheering on Sora and his friends.

Once Ne Zha breaks free from his pot in Fengshen Yanyi 2, Ziya and his party agree to continue looking for the other mystical comrade from Taigong Wang's previous journey before heading back to West Qi. Based on the advice of the boy's master, they head to the northern gate, Qinlong Pass. When they arrive, no one is there so Ziya asks one of his party members to cry out to him, which mistakenly attracts monsters and Savage Beasts. Defeating a group of them with some effort, lightning suddenly strikes the ground and Lei Zhenzi, in his bird form, flies in the air above Ziya's group. Ziya mistakes Lei Zhenzi as another monster until Deng Chanyu beckons the boy to land. Transforming instantly into his human self on landing, he pouts at how Ziya couldn't recognize him but brightens at the thought of another journey with his friends. While traveling through Emperor Ling's realm, his spirit momentarily takes residence within Huang Feihu's body, but this is reverted when Ziya's party disables the transmigration. He returns home after the final battle.

In Mystic Heroes, Lei Zhenzi is a NPC ally who assists the player's party by flying to high places.

Personality
Innocent and friendly, Lei Zhenzi is an excitable child who simply wants to play. Gifted with the ability of flight, he loves to explore new places when he is granted the permission to leave Kunlun. He refers to himself in third-person, often as "Rai-chan" (らいちゃん). As the youngest member of the party, he fondly calls everyone his "older sister/older brother". He especially likes Ne Zha but the latter simply can't stand his gushing affections for too long. While he doesn't do it often, Lei Zhenzi can speak the bird language (a series of chirps and tweets) and tries to teach it to his friends for fun.

Fighting Style
Lei Zhenzi is the only party member who can fly over people and obstacles, beating levitating characters with the height of his flights. For his first appearance, his luck and physical attributes are among the weakest in the party. However, he is quite fast and an adept spell caster. Specializing in offensive magic, he can perform hit and run maneuvers from a long distance. He can simply fly to a high spot on the map if he has sustained too much damage, as a majority of enemies will not be able to reach him. Players who use him well can also use him to punish the hard-to-hit flying enemies in the game, since Lei Zhenzi will have a significantly better chance of hitting them than his walking allies. His default ability is a powerful lightning attack; it is a cheap costing attack to help him hit his enemies.

His attack and defense improve slightly in the sequel. His attacks have also have an additional wind element attached to them, making him able to target groups of foes with relative ease.
