sentences:  When Superman is accidentally drawn into the future when the resistance attempt to retrieve a Terminator sent into the past (the resistance including a future version of his friend Steel), Skynet manages to incapacitate him using kryptonite, having acquired information about how to duplicate it based on data hidden in a salvaged Terminator skull by the Cyborg.Although Skynet sends Terminators into the past equipped with rockets and other bonus features to delay Superboy and Supergirl, Superman and Steel are able to destroy Skynet in the future by detonating a massive electro-magnetic pulse, Superman returning to the past to destroy the last of the Terminators.Although the storyline ends with Cyborg and Lex Luthor speculating that they will be in charge of Skynet when it is activated, this is never followed up.
