Clicking on the units reveals various humorous phrases. One of note is by a Protoss hero unit, Artanis. He states that, "This is not WarCraft in space!"

The Protoss hero Artanis is Praetor of the Templar caste. However, as seen particularly clearly in the ending movie of the Protoss campaign, his psychic tendons (the 'dreadlocks' on top of his head) are cropped in the manner of the Dark Templar.
