In the [i]BattleTech[/i] universe, the [i]Timber Wolf[/i], also known as the [b]Mad Cat[/b], is a Heavy-class Clan OmniMech known for its versatile armament and fast speed for a 'mech its size. The nickname "Mad Cat" comes from it bearing similarities to the [i]Marauder[/i] (MAD) and [i]Catapult[/i] (CAT) 'mechs.

The [i]Mad Cat[/i] is also easily one of, if not the most recognizable 'mechs in BattleTech and possibly one of the most well-recognized out of all mecha in media. It has gone from being on the box art of [i]MechWarrior 2: 31st Century Combat[/i] to being in the logo for the modern [i]Classic BattleTech[/i] brand. For many, this 'mech is the one that represents BattleTech and MechWarrior, a testament to its popularity. So, when you see it, you can probably easily say what giant robot franchise it's from.
