Desty Nova's brain bio chips

[vahid]

How was Desty Nova able to create Nova II after Jim Roscoe removed Desty Nova's biochips from his body and they fell into the hands of Alita and ping Wu?
It seems, both the main chip and the backup chip were removed from Desty Nova's body, but later we saw that Aga Mbadi extracted another chip from inside Nova II's brain. Can Nova create new chips from himself? If so, why did he need a backup chip in his stomach?"

Nova II (later Super-Nova) is a sterotonomy clone create by nanomachines that triggered as soon as the original died. He is a 1:1 replica of the original down to the neural pathways.

Sterotonomy is what created Flan Nova and the numerous decoy-clones that caused so much trouble in chapter 120-122. This is explained in depth on the cover of chapter 122.

Nova made himself immortal, his nanomachines can rebuild his body (and brainchip) in almost any circumstance, however the process takes up a few days, so for the sake of fast recovery he carries a backup brain chip inside his guts.
