<P> Lockdown returns to capture Optimus and the Dinobots , using a large magnet in his ship that picks up and drops metal objects , causing destruction to the city . After disabling the magnet , Optimus fights Lockdown at an abandoned factory . In the ensuing duel , Optimus kills Attinger ( who still angrily deems all Cybertronians aside from Lockdown as a threat ) to save Cade , and avenging the deaths of his fellow Autobots . However , this allows Lockdown to pin Optimus down by impaling his chest with his own sword , damaging his spark . Cade , Bumblebee , Tessa , and Shane fight Lockdown , with Cade ending up fighting him one - on - one while Tessa and Shane use a tow truck to free Optimus , who kills Lockdown before using one of his grenades to finish off the remaining drones . Galvatron retreats , vowing to return . As Lockdown 's ship leaves Earth , Optimus tells the Autobots to protect the Yeagers ( with Joshua offering to help the Yeagers build a new home ) and lets the Dinobots go , before flying away into space with the Seed to hide it away , sending a message to the Creators that he is coming for them . </P>
