Not likely, Ener is the most OVERRATED character in One Piece. As for how high his rank on the blue seas is concerned…....It will be as high as the clouds because his ass will be knocked back up stream to Skypiea!
You must have been on some other forum with a bunch of Enerist priests. Here, everyone either loves the guy (Like, 15%) or hates him. He is VASTLY underrated and most people bring up Luffy's quote on how "weak" he is. Luffy wasn't talking about random pirates like Foxy and Kuro, he was reffering to the big boys: Like yonkou, the stronger marines and the schichibukai. Saying something so bold becomes moot when the person your bashing can't hurt you.
Really, I don't get why you think he is overrated, bit he is indeed powerfull, this is fact.
Considering Bellamy's crew in the first half of GL never even saw a 100 million berry pirate, and that the East Blue's highest was 20 with an average of three, the other Blue Seas couldn't be too much higher. In the North Blue, I think Bellamy must have been one of the top dogs (Kind of like Krieg and Arlong in the East Blue). With a bounty of 55 million, he must have either gained his rep there, or got it in the GL.
Considering how often the North Blue is referenced, and that Bellamy's bounty was exaggerated, I'd say the former was the case. This meanse the average in NB must be no more than around 60 at best.
Now, Eneru's bounty would be 500…how on Earth would the regular Blue seas be any competition for him...? He can be veeery persuasive (your life), has mantra, and can wipe out an island. Definitely Schichibukai material. But his "Survival of the fittest" attitude would place him at odds with the W.G. They may try an all-out assualt and wipe him out while they have the chance (Most likely). Personally, I believe Eneru would raise an army, take over one of the Blue Seas (Since it would be much easier and the strong marines in the GL wouldn't bother going there) and do what he does. The W.G would have one of the Cipher Pols on duty in his area, but wouldn't attack first.
Enel seems really strong right now. but soon he's going to be outclassed to the point where he looks like a bug.
**Maybe Phenomenol was talking about you…your expecting too much from the bounties and Yonkou. Most of Eneru's huge bounty would come from what he can do to threaten the W.G, not from how many ships he can fry off the face of the Earth. You have to remember that bounties are issued by a government that goes crazy the moment anyone revolts. They hate revolutionaries and people who know how to take over nations (Like Dragon and Crocodile). Eneru isn't just powerfull, he makes an excellent tactician and is organized. He also knows how to use fear.
I'm not telling you to change your views on the bounty=Power-level issue (As you are actually very close to the truth on this issue), just saying you may be expecting too much from how high the numbers are climbing.**
