Before 5 Years Later
- Prior to the events of 5 Years Later, Crawnch's childhood was filled with challenges. he grew up on the poorer side of his home planet, where crime ran rampant, but he was always the one to oppose it. He received a lot of scars since childhood, always from protecting others.
He knew he wanted to become a plumber ever since he heard his father, Ez'rah failed to do so, why he failed was never revealed to him, but he most likely chose to stay to protect his family and community, rather then the galaxy. He was a military man at heart and raised Crawnch and his younger brother accordingly. Crawnch joined the plumbers at a young age, and he showed a lot of promise.

The life form alert then goes off, causing the Orion Squad to go to the teleport hub and prepare for action.
