Thaddeus Bach was a promising Peacekeeper. He soon moved up to the ranks of Eidolon Elite. He caught the attention of Quartermaster Temple and was recruited into the Wraith. The Wraith was the embodiment of the Eidolon. Only the best of the best were able to join the Wraith. They take on the most dangerous missions that no one else is capable of. This concerned Thaddeus' pregnant wife, Elua Bach.
On a mission to meet a weapon dealers. Tower decided to kill him and take his weapons and money. Thaddeus had a severe problem with this. Even though the dealer was a bad alien, they had trials and procedure. Tower told him the Psi-judges aren't perfect and it's their jobs to punish those who are evil. He tells Thaddeus that all he needs from him is five cycles and then he could retire from the Wraith.
That night, while Elua is sleeping, Thaddeus wakes her and says they need to leave, now. Unfortunately, there were a couple Wraith members were in his home cloaked with invisibilty tech. He is knocked out from behind.
Later, Thaddeus wakes with Tower telling him how disappointed he was. He also finds out that his wife and unborn son were brutally killed. Thaddeus snaps and attacks them all. Out manned and out gunned, he he shot. Later, Tower announces that Officer Bach was killed in the line of duty along with his wife and unborn child. He is beaten some more and left to die on a ghost planet.
Thaddeus is saved by an alien named Solomon. After over a month, Solomon revealed to Thaddeus a secret he'd been keeping from him. He said he was only going to share it with him because he knew he was a good man. He tells him how he was born into war and also created weapons. It was the creation of those weapons that killed everyone on his planet while he hid in shame and cowardice. When Thaddeus sees a ship, he asks if it works. Solomon can see the lust for revenge in his eyes and pleads for him to not follow that path. Donning the power bands Solomon created and wearing a hood and cape, Space Ghost is born.
