Chang Tzu was is the scientific master of Oolong Island and employed as a weapon smith by Intergang. Chang Tzu established a collective of "mad" scientists dubbed the Science Squad. The Science Squad were chiefly responsible for bioengineering four immensely powerful beings, which came to be known as the Four Horsemen. One of the Science Squad members, Will Magnus, finally had enough of the evil being perpetuated by Chang Tzu's scientists and turned against them. With the aid of miniaturized versions of his Metal Men, Will Magnus killed Chang Tzu.
Though he has been killed on more than one occasion he never fails to reappear eventually. He has hinted that his "resurrections" are accomplished through cloning.
- Unique Physiology: Red eyes, yellow skin which resembles an eggshell, lacks arms and legs, areas around eyes and mouth have a "cracked" texture.
- Chang Tzu's name is presently unclear as it has been inconsistently presented; he is introduced as Chang Tzu, but is subsequently referred to as both Chung Zhu and Chung Tzu. It may be possible that he has multiple names; Chang himself explains that "Egg Fu" is one of his "Nine thousand and nine unmentionable names", and immediately kills a guard who laughs at his mention of it.
