Wolverine and The X-Men - Rover

When an explosive event shatters the lives of the X-Men and takes away their mentor, the beaten heroes walk away from it all. Wolverine, the most legendary of all X-Men, reunites them to prevent the world's destruction. In the future, Professor X is trying to learn of the events that led up to the war so that Logan can try and stop them from happening in the present. Bishop suggests they sneak into the original housing facility of Master Mold to collect the data storage from its last upgrade, which might hold some clues. But the facility is heavily guarded by Sentinels, and they would need a distraction. Bishop suggests Rover, an old model Sentinel that has been accompanying them since the Badlands. But Marrow refuses to lead him into a suicide mission for the sake of the Professor's personal agenda. Bishop reminds her that he is the leader, and she does not have a choice. Once inside the facility, they find the data storage core just as the exits seal shut, trapping them in. Bishop radios for Marrow, who has taken Rover and abandoned the team. Rover turns back to help, seeing the facility under attack, despite Marrow's pleas. Her teammates make it out alive with the core thanks to Rover's heroic crusade. But soon more Sentinels arrive, overwhelming Rover. He gathers the last of his robot strength to fight them off, for just long enough for Marrow to escape. The victory of the recovered data is bittersweet, as the team lost a dear comrade, and Marrow is especially upset. They successfully extract the info they were hoping to find, and Professor X contacts Logan with the news that he has eight days to stop the war that is to begin, and that will push Jean to use her devastating powers.
