Kraang Power Cell

The Kraang Power Cell is a source of power that was used to control The Kraang's portal to Dimension X but the mutant alligator, Leatherhead stole the cell to keep The Kraang from coming to Earth from their Dimension.
It served as a key element to their Invasion Plans.
It was destroyed in the final battle at T.C.R.I.
