"Osiris" is a program to revive Deltron's consciousness long after his death.
In Melding of the Minds he came so close to death he saw fit to back up his mind in a server—which was eventually found and downloaded into the cyberbrain of a different cyborg centuries later. This is the only time he refers to himself as "Deltron Osiris" apart from the timeskip to the year 4010 where he finally "rises from the ashes."After threatening a building with a rocket launcher in Verse 2, he suffers severe injuries and is brought to a safe haven:
"With needles and threads, trying to sew him back
After his neck explodes, fade to black
Deltron Osiris, he made it back
To the underground Matrix, a maze for the haters
A place where danger's seldom brought in"
As he creates the backup to implant his mind into who finds it:
"No casual contact, so fuck the format
Consider this a melding of the minds
A secret message transmission to all kinds
Undergo my process of understanding
Assimilating, absorbing knowledge as the hand swings"
Nearly a millennium later someone finds his message and downloads his mindstate, taking on his persona and becoming the new Deltron of their generation:
"Who was kin to the previous champion
In three thousand thirty, but now it's four thousand ten
From the ashes I arise with
The new style is Deltron Osiris
Osiris, I'm here in the afterlife"
He's "in the afterlife" literally since it takes place after the original Deltron's death.
