Ultimately, it took a great deal of effort for Fang Zheng to change the way the little creature addressed him. In fact, he realized that the little one was hearing him but not understanding. Originally, Fang Zheng had hoped the little guy would call him "Elder Brother," but the little one clearly would not budge on this, so Fang Zheng had no choice but to raise his hands in surrender.
Now that the little guy could transform into a human, Fang Zheng naturally could not keep calling him "little guy." He had to give her a proper name. Originally, Fang Zheng wanted to choose "Onyxia" or "Chromie," but considering that both names didn't seem very auspicious, he eventually settled on a more conventional name—Wendy.
What surprised Fang Zheng the most was Wendy's abilities.
