"Nice bike..."
"It's not a bike. It's the Middlehog."
- Wendy Watson and the Mirror Middleman
In the Mirror Universe, the Middlehog was the primary mode of transportion for the Middleman. It is an extensively modified Harley-Davidson motorcycle.
The Middlehog was sacrificed when the Middleman rescued Wendy and Mirror Lacey from Fatboy Command, as they were forced to escape on foot. However, before departing, Wendy raised the possibility that the Middleman might, "storm the gates and take it back".
