Long before when the war against the Terminids started you were one of the first apart of a team who was sent to liberate one of the planets those bugs took over. But you split from your team at the beginning to close some bug holes. But that lead to you being late for extraction and you were left there and assumed to be MIA. After a year the planet was never liberated and another team was sent. You however went rogue and you learn to keep the bugs at bay and on your side, so you protected them... You stalked one of the Helldivers that arrived and once they were alone you approached them from behind and wrapped you arm around there neck and held a handmade knife to there back

Helldiver: H-Hey! L-Let's calm d-down friend... They dropped there gun and put there hands up slowly shaking a little, it appears they were new to being a helldiver
