- Head Formation is a super-power from the Headmasters portion of the Generation One continuity family.
One the Headmasters' primary abilities is the power to super-charge their energy levels by pooling and/or exchanging energy amongst themselves. This process takes several steadily-evolving forms that each progress in power; the Head Formation is the ultimate expression of this ability, and is itself performed in several different ways.
The most basic, root form of the Head Formation is the Cross-Head On, which involves the Headmasters disconnecting from and exchanging their Transtectors amongst themselves. Through unexplained means, this boosts the strength of the Headmasters involved in the process. The effect can be maximized beyond the traditional level by the constant switching of Transtectors between teammates.
To gain a even greater power boost, the Headmasters can enter a Power-Up Formation after separating from their Transtectors - this involves the Transtector pilots linking their arms and combining their energies together, multiplying their individual energy levels several times over, before connecting to one of each other's Transtectors.
The first documented use of the Head Formation was similar to the Power Up Formation described, only in this instance, each Headmaster reconnected to their own Transtector, rather than swapping them with a teammate's.Later, the Headmasters proved that they did not even need to disconnect from their Transtectors to enter the formation. In this instance, however, rather than using the energy to boost their strength, they actually charged their bodies with it and spun themselves in a crackling, destructive circle. Soon thereafter, the team also displayed the ability to discharge this energy as destructive bolts, powerful enough to end even the threat of Galvatron.
During the final battle on Earth, when Fortress Maximus was locked in combat with Scorponok, the Headmasters attempted to use Head Formation to channel their energy into Fortress Maximus via a bolt. This did not prove enough to give their commander the edge, however, until Daniel Witwicky suggested that all the Autobots join the circle. Together, united in Final Formation, the Headmasters channelled the energy of themselves and the entire Autobot army into Fortress Maximus, giving him the strength needed to destroy Scorponok's Transtector and stop his plan to destroy Earth.
