Green slaadi appeared as the result of an infection of a humanoid spellcaster by a red slaad egg or a blue slaad's chaos phage. If the infected humanoid could cast sufficiently powerful spells, instead of a red or blue slaad, a green slaad appeared.
Beside their spellcasting abilities, green slaadi were also shapechangers and could assume the form of other humanoids. They usually chose to assume the form of their former hosts.
