The name or term Runamuck refers to more than one character or idea. For a list of other meanings, see Runamuck (disambiguation).

Runamuck is a Decepticon from the Cybertron portion of the Unicron Trilogy.

Oh, what's this? Is that a tear, Pantera? Is Daddy's little girl upset?

Runamuck was very very bored during the years Megatron was gone. Having served under him as a spy and messenger for centuries, the peacetimes under Autobot rule gave him little opportunity for his brand of fun: blowing stuff up.

With most of Cybertron's population on Earth due to the appearance of the Unicron Singularity, Runamuck has been given a chance to cause some real havoc, knowing that the Autobots are forbidden from revealing themselves to the inhabitants of the haven planet. He likes striking human settlements directly under the nose of the hidden Autobots and relishes their frustration in not being able to use their robot modes to stop him.

He was once hog-tied by Swindle.

Japanese name: Runabout

Unlikely and Unlikelier

A retool of the Armada Autobot Side Swipe, Runamuck transforms into a Nissan Skyline street car with exposed engine block. Inserting a Cyber Planet Key into his engine activates his spring-loaded transformation to "dragster" mode. In robot mode, this becomes individual trigger-activated arm-mounted attacks. In both modes, he can store his rifle in his rear-window compartment (which can also store the Mini-Con Nightbeat mold). The mechanism for the Mini-Con Powerlinx-activated left-arm "punching" gimmick from previous versions of the mold is still present, but may not work at all due to mold-wear. He came with a silver-bordered Earth-style Cyber Planet Key, plus an all-new, non-firing hand-weapon.
In Japan, he was only available in a double-pack with Longrack. He is one of the very few regular-retail Galaxy Force toys to not appear in the cartoon.
Though the other versions of this mold included a Mini-Con partner, no release of Runamuck had one. The Mini-Con partner mold was released only in the Galaxy Force Micron Booster wave as Gauge.
This mold was also used by the Universe Decepticons Oil Slick and Treadshot.

Runamuck is unfortunate enough to suffer from both "Hoodhands" and "Sideways-Knee".

Sold individually by Hasbro, this version is identical to the Takara release, save his Cyber Planet Key, which has the Cyber Key Code "dw3e" tampographed on its back.


  • Runamuck was originally created by Takara as an homage to the Generation One Decepticon Runabout and had that name. But for his Hasbro release, he was given the name of the G1 character's similarly named partner, "Runamuck", due to inability to secure the trademark on "Runabout".
  • The online version of Runamuck's Hasbro bio is different from the card-back version; while the front half is the same word-for-word, the final portion of the online bio places him on Cybertron, causing trouble for Longrack.
