I thought not. It’s not a story the rebels would tell you. It’s a Combine legend.
3650 was a member of Civil Protection, so powerful and so badass, he could use Lazlo’s algorithm to influence the rebel's turrets to shoot at…themselves. He had such a knowledge of what transpires in City 10 that he could even prevent the vortigaunt conspiracy from succeeding.
The good graces of the Combine is a pathway to many abilities some consider to be unnatural.
He became so badass, the only thing he was afraid of was losing his family cohesion, which eventually of course he did. Unfortunately, his colleagues dug the dirt on everything about his past, and 3650 killed them all on the spot.
Ironic. He could keep the humanity on other people, but not to himself.
