The evidence for this is overwhelming:
- Xebec turned out to be a good guy, and Oda doesn't allow good guys to kill.
- Xebec's moment was in the flashback, and Oda didn't even bother to show any of the supposed fight against the admiral. If Xebec defeated him, why not show something to hype Xebec up?
- Xebec is too weak to kill an admiral:
• It's already been shown that all the great pirates became much stronger after God Valley and far surpassed him.
• Even if Prime Xebec were a Top Tier pirate, he was clearly a novice; he should be far from an admiral in any scenario.
My theory is that Imu killed the admiral. Imu is the only one with enough power to do it.
Imu likely pursued Xebec, encountered the admiral, and they fought until the admiral was critically wounded.
This allowed Xebec to escape, and the World Government later blamed him.
