Pre-series: Sinbad conquering the very first dungeon fourteen years ago.
Alibaba revealing his superiority over Jamil in every way in Amon's dungeon.
How about when Aladdin tells him that he is unworthy of being a King Candidate? Considering what Jamil has done, it's nice to see this spineless bastard getting an emotional kick to the groin like that.
Morgiana overcoming her fears and traumas of slavery.
Alibaba and Aladdin beating their first dungeon together.
Hakuei revealing that she's a general in the Kou Empire for a reason.
After being constantly overshadowed by the magically gifted Aladdin and physically powerful Morgiana, Alibaba steals the spotlight with his first appearance blocking the ultimate attack of Reim's top general, that had the potential to destroy an entire city, with an attitude of casual finesse.
Try the arrival of Sinbad and his Seven Seas Alliance, all Djinn Equipped and ready for battle. And to top it all off, Morgiana finally appears after 20+ chapters to save an exhausted Alibaba.
Of all people, the two Flame Djinn users, Ren Kouen and Alibaba, work together to destroy the defensive wall of Al-Thamen's father.
Basically, ANYTHING AND EVERYTHING HAPPENING ON THE BATTLEFIELD BETWEEN THE FULLY DJINN EQUIPPED METAL VESSEL USERS AND AL-THAMEN'S FATHER.
Such sights include stuff like 13 Djinn Equipped metal vessel users utilizing their Extreme Magic at the same time!. And that still wasn't enough to beat him back!
Chapter 208: Alibaba was requested to kneel in front of Kouen, in Balbadd. Considering Alibaba is the prince of the country, there is no bigger shame than a prince kneeling like a commoner in front of the entire court. Balbadd's soldiers were about to grief for him for bearing such humiliation but Alibaba's answer is, he told to Kouen's entire court and Kouen himself that he doesn't mind kneeling in front of him, but it's a custom in Balbadd to kneel in front of a pregnant woman to wish for safe childbirth, terrorizing the thoughts of Kouen's court that by getting Alibaba to kneel before Kouen is to treat Kouen AS A PREGNANT WOMAN!! Yeah, Alibaba, the Butt Monkey for the past few chapters, outsmarts the entirety of Kouen's court. AWESOME.
Chapter 244: Though it also doubles as a case of Moral Event Horizon, you have to admit that Hakuryuu and Judar forcing a Djinn, a freaking Djinn, into submission against his will speaks volumes about how many levels in badass they took while off-screen.
