[Lord of Nukes]

Ultralisks are awesome with Zerglings. The Zerglings do huge amounts of damage, but the Ultralisks are higher priority attack units. That emans they'll soak up damage from the enemy as Zerglings decimate the enemy base. They work best to soak up damage, usually they aren't worth spending a lot on, but sometimes they can be incredibly useful for a Zerg player.
