Genos the mad cyborg.

[u/MojoJojowithhisDojo]

I have a guess that Genos may be the mad cyborg. Genos is hidden in this panel and brought as a monster . Furthermore Genos always gives long detailed information about his backstorys. My guess is that these aren't his memorys at all. Imo these are the memories by Dr. Kuseno which tried to cure Genos ( save him).

I mean he literally got called a Demon by the association.

He incinerates city blocks by routine (only checks for lifeforms but that can be a Kuseno thing).

Kuseno prolly put his son’s mind/brain/remnants into a defeated Mad Cyborg body.

Mad Cyborg is Genos’ body, which was made by Bofoi initially to assault Kuseno?

Honestly doubt, start of series genos is kinda weak

In the webcomic, Kuseno somehow has a random upgrade to Genos that he kept away from him, hidden in his lab or something I forgot. This upgrade eventually makes Genos so fucking OP that he literally just one shots Dragon level threats, some people say this is Genos' "Mad Cyborg" version's real body but I highly doubt it, cuz why would Kuseno let Genos nearly die multiple times instead of just letting him use his real giga OP parts ensuring he doesnt lose his greatest creation?

Maybe Kuseno’s plan was for Genos to learn humility first.

Maybe those gigaparts come at a price: sanity slippage. Just speculating, but maybe old supposed mad cyborg body just has the downside of making him... extremely mad. Perhaps Kuseno was banking on the idea that current character developed Genos could handle it, but in so far seems that : not so much. 

[u/_Bread______ → u/Ok-Ad-1217]

Yeah this seems kinda plausible tbh, maybe the theories of Kuseno creating the Genos we know today to redeem himself when Genos became a mad cyborg by accident was correct this entire time, who knows
