He is though his streak says otherwise.

Despite the statements I don’t think he’s stronger than jigen. It’s never stated which version of jigen either. Neither Amado or code have ever seen V2 Jigen or Juubi amped Jigen. Code is an absolute fraud and a clown. He claimed he could beat rinnegan Sasuke and SPSM Naruto. Then he avoided a direct confrontation with Sage mode Naruto and when he got his limiters removed and the 10 tails he lost an eye to a heavily nerfed sasuke. After getting two power ups! He claims to be powerful but then gets one shot every time he’s on screen.

Reasons why Code is a Fraud...

1. Said he could beat Naruto at his best with no Problem... Then avoided direct combat with Sage Mode Naruto, and was surprised Isshiki was killed (thx to BM Naruto)

2. Got his Limiters removed and was implied to be stronger than Jigen... Proceeded to get bodied by someone actually stronger than Jigen (Daemon) and later even lost his eye to a nerfed Sasuke with no Rinnegan...

3. Got dripped out like Dracula, than got bodied by a Base Boruto not even truly trying, and than also got bodied by the evolved Juubi's...

4. Runs from every fight his in, and uses outside means to win or get away...

His a fraud and a Clown... Followed up by Kawaki (man was it satisfying to watch him get one shot twice in 2 chapters lol)

Considering the fact that all of the cyborgs created that surpassed jigen were quite literally to kill jigen then I think he is also there'd be no reason to have all these characters state a falsehood

His power is, but he himself is an idiot who doesn't know how to use the power he's been given.

Code is stronger in terms of chakra. But as fighter and battle ability Jigen stomps.
