One of four survivors from the Splinter attack (in the game from which the manga is based, Metroid Prime 2: Echoes, there are no survivors), Samus Aran found Klaus being attacked by an Alpha Splinter, and just when it was about to move in for the kill, Samus shot it off of him. This killed the Alpha Splinter, but Klaus, recognizing Samus, urged her to finish it off before the "black fog" came and took it. However, she was too late, and Klaus fled while she killed it.
