On Char, Zeratul met the former protossexecutorTassadar, a member of the Templar Caste, and the terranJim Raynor. Tassadar reacted badly upon his meeting with this leader of a forbidden caste and attacked Zeratul. However, Zeratul refused to take offense, even attempting to teach Tassadar the art of combat. Eventually Zeratul overcame Tassadar's prejudice, beginning to heal the rifts between the Khalai and the Dark Templar. The two leaders (and Jim Raynor) came to an understanding, joining forces and hiding from the zerg.
Zeratul’s ability to create havoc in the backline forces Auriel into really difficult situations. Zeratul is good at picking off the fragile Auriel, or her Bestow Hope target, without opening himself up to damage that would fuel Auriel’s healing. As an answer to this, Auriel might want her team whole team to group up together - but this can set them up for some nasty Void Prison setups.
Lúcio doesn’t have much Health, and his main source of protecting himself is via his knockback and increased Movement Speed. Zeratul preys on low-Health targets and has multiple ways to close the gap, making him an especially difficult foe to shake off.
Probius has trouble with heroes who can consistently get to him, and no one is quite as good at that as Zeratul. Zeratul has a plethora of ways to get to Probius, and he can often safely retreat if things go south once he engages. Both Shadow Assault and Void Prison are also great tools for catching and eliminating Probius if he is even a little out of position.
In similar fashion to Illidan, Zeratul can quickly combo his abilities on Stukov before the infected Terran can even get a Lurking Arm silence going. Zeratul’s Blink tends to counter both of Stukov’s Heroic Abilities as well.
Zeratul was conceived within the first two years of the game's development. He appeared in early builds of the game. His abilities allowed him to move quickly and confuse the enemy. He benefited from dexterity items. He had the following stats and abilities:
