Nah, he only had an upper 2k power difference. It's probably less when you factor in both MC and Deryl combined power pool. Which should come out at around 1k to possibly 1.2k.
The biggest L actually goes to Origin MC. He lost to Deus, who's noted as being Level 4 by Lisa. Though Valravn states he has more power than even Nico, who is Level 5. Then Origin MC arrives again and gets one shot by Bernhardt. He's legit 0-2.
You might say those aren't bad, but when you realize he's potentially an Arbiter, or at minimum above the Apostles, he starts to look like a bum. Even moreso since he is aware of his past Ls and still chooses to go and lose anyway.
Bro the Eye, after possesing a level 2 Mc, was able to consume Michael, Deryl, Alice, and that diamond chick in a instant ( through his sentence regarding his hundreds of tails feeding on ''something'' ), he neutralized Alexis, a level 5, after a mere MOMENTS of battle, killed dozens of monsters instantly, and made Goliath submit with his mere presence alone.
Then a single evolution later he was able to consume EVERYONE in the artificial world made by the Hexenringe, correct me if I'm wrong but this includes SO many people, again, Michael, Alice, Liz, Amber, Thanos, Cole, Briar, the rune chick, Met, Rina and most of S.I.N, and since it stated he consumed everyone then it prolly means Shen aswell, and ofc the Hexenringe itself who is stated just gave up and waited to be consumed PLUS hundreds of monsters that were going rampant in that dimension, and this was MOMENTS after he got loose, think about it.
It is my understanding that he in both ressurections was looking for Ella, in pursuit of consuming / rejoining with the 3rd and 4th, hence him saying he ''needs atleast one'' of the two, when he thinks of fighting the big three.
When you consider who he lost against it is no wonder he lost, Deus literally went back in time to sever the timeline, and Bernhardt is literally the strongest being in existence bar the apostles.
You got 4 names who/can beat the eye in his two incomplete forms, 1 can literally erase you from existence by time travel and the other three are the last bullwarks of humanity. Yet FAR from complete the Eye would've stomped anyone else.
If we're being fair the biggest L goes to Valravn, dude loses his heart, botches his whole life's purpose, gets defeated and captured, then is set free only to lose to a level 2 and end up captured AGAIN.
