To a Power Unknown!

In America, a group of Autobots is forging relationships with humans, when an energy blast hits them and makes them aggressive. Similarly, a group of Decepticons is attacking a town when the energy blast hits them and makes them well.....nice!

When both groups have recovered, they track the source of the energy blast to the United Kingdom and a group from both factions sets off to find the source, each group believing the other is to blame for it. On a patrol, Starscream spots Optimus Prime in truck mode and attacks him. As he unleashes a missle another energy blast strikes the transformers, reversing their personalities again. Starscream wonders why everyone can't be friends and the Autobots travelling inside Prime (including Jazz, Mirage and Prowl see Prime as useless and try to attack him.

As the effects of the blast fades Prime orders the Autobots to leave and find the source of the blast as Starscream comes in for the kill. Prime is a sitting duck but Starscream is forced to pull out of the attack with a systems failure leaving Prime to realise that maybe the Decepticons are not the source of the blast. Badly injured, Optimus finds shelter in an old railway tunnel.

The source of the energy blast is in fact the Core of Pard, developed by the British as a weapon to abort attacks by making the attacker attack themselves. But a traitor, Hellman, tries to steal the Core of Pard, inadvertantly releasing a blast that both Jazz and Starscream feel. Jazz, slightly damaged by the blast, homes in on the research lab. Running out carrying the Core of Pard, Hellman sees the porsche as an escape ticket and jumps in. Jazz lets the human think he's in control for the moment.

In the meantime, Starscream is forced to land nearby after an encounter with the Red Arrows. Hellman thinks the landing plane is for him and runs towards it and climbs in. Starscream takes off. Jazz, transformed by this stage, fires a heat seeking missle at Starscream as the Deception plans to use Hellman to make the Core of Pard affect only Autobots. Starscream plans to outrun the missle with his hyperblast but his systems are still scrambled and he transforms instead, meaning Hellman and the Core of Pard are destroyed by Jazz's missle. Jazz and Starscream battle until being interuppted by the Royal Air Force.

The story ends with the Autobots, now fully restored, bringing a badly damaged Optimus Prime back for Ratchet to repair.
