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

Jack is a Mini-Con from the Cybertron portion of the Unicron Trilogy.

Jack is one of the many Mini-Cons caught up in the events caused by the Unicron Singularity. He is teamed up with Dice and Plug.

He does not wield a magic sword, and he is not seeking a way to return to the past and defeat Aku. As far as we know, anyway.

And he's definitely not the Red SPD Power Ranger.



  • Jack (Micron Booster, 2005)
Booster ID number: 11
A redeco of the retooled Cybertron Street Speed Mini-Con Team member Spiral, Jack transforms into a modified Mercedes C-class luxury car. Available only as part of the fourth Micron Booster assortment in Japan, Jack came in a "blind-packed" box that prevented the buyer from knowing the contents of the box until it was opened.
The original version of this mold is also used by Servo and Skid-Z. It was originally meant to be used for the Energon Mini-Con Clocker to be packed in with Energon Ultra Magnus, but was ultimately replaced with a different mold set.
