Synopsis
Four members of the Lightning Strike Coalition were captured by Shockwave (while the fifth one was left in stasis lock) after repelling his Insecticon hordes and re-engineered to become much more powerful and transform into alternate forms that resembled creatures he discovered on a distant planet. Though four of the team escaped captivity, renaming themselves the "Dinobots".
