More theories:
Moria (who looks like a Bat-man) will ultimately do away with Doflamingo (Joker)
Aokiji is the 10th commander, but also a double agent:
- After Block C, Luffy runs into Burgess, who is in the midst of talking with his captain about his distrust for Aokiji. Blackbeard reminds Burgess that the situation with Aokiji is like the situation with Shiryu (In which, Shiryu was also a member of the World Government, but is now a crew member)
- When Aokiji shows up on Punk Hazard, Doflamingo states that he's heard some unsettling rumors regarding the former admiral.
- And this is the one thing that has been bugging me since Jinbe stated it: Akainu let Aokiji live. Doesn't this just seem completely out of character? They were having a duel to the death. I mean, anyone who has seen the latest movie can attest to Aokiji's scar (which is starting to become Akainu's trademark), so there definitely was a fight. But why spare Aokiji? We've seen how heartless Akainu is, even against his own marines, so pity does not fall in line with Akainu's personality. DECEPTION, however, fits perfectly (as we saw with Squardo during the War of the Best).
Here's my guess. Akainu defeated Aokiji, and scarred him for good measure, but let him live so that he may serve a higher goal: To bring down Blackbeard. It's all an elaborate ruse. And that's precisely why Aokiji returned to Punk Hazard; it's his check-in spot with Akainu. Now, I'm not saying he met with Akainu there during those moments, but it's probably a "home-base" for whatever plot they devised together.
