Chad is a regular healthy male cow, capable of making sounds and moving. It doesn't belong to a specific family however.
Chad has regular behavior for a cow, such as moving, looking at humans, mooing sounds and much more. It's required that it can be served grass and milk to keep it alive and healthy. It is also recommended to keep it and its habitant away from any propiatary building, including Morning Star and the various buildings once owned by or currently owned by E-001, alongside preventing it from escaping by any means and keeping his habitant on 24/7 watch, see incident 'The Cow's Game' for explanation.
Whilst the team was on a lunch break, Chad managed to get out and walk away from its habitant. When Morning Star researchers made their way back to feed it, they found him missing and conducted a search for him. Morning Star employees would later find Chad in Wario's Fast Food Factory, which had many people inside during business hours. Although people were confused at first, chaos ensued after Chad began to exhibit anomalous behavior, such as summoning E-040 and replicating effects pertaining to E-095.
Morning Star would arrive 10 minutes later, evacuating everyone and setting the building on lockdown as they contained Chad and took him back to his habitant. E-040 would be re-contained and E-095's effects would be neutralized in the building, allowing them to lift the lockdown.
