And later he is capture by Lahap and taken to their spaceship.





  • Ejo Jo is also known to be one of the most evil and insane antagonists in the series, with the other being Bora Ra, due to the fact he is way more villainous than Adu Du and nearly killed the protagonists. However, Ejo Jo is not Pure Evil like Bora Ra, due to his mild comedic traits, and also, he has been outranked by Captain Kaizo in Season 3. Despite all of this, he is still considered as one of the most serious threats that BoBoiBoy and co. has encountered.
  • Ejo Jo is the foremost antagonist of BoBoiBoy franchise because he forced Adu Du to leave Ata Ta Tiga.
    • The Emperor of Ata Ta Tiga is the other Heavy of the series.
  • He is the first alien who takes BoBoiBoy's gang's power bands, and the second is Captain Kaizo (although in the end, Kaizo decides to trust them and let BoBoiBoy and the other to take it back).
  • There were rumors that he was one of the famous team of mercenaries on the Planet Ata Ta Tiga.
  • A recurring gag over Ejo Jo is that whenever he introduced BoBoiBoy and co. his newest arsenal that is more superior than those of his rival Adu Du, they have notoriously humorous names that the protagonists laughed at him for it. This greatly dismayed him that he had to bring the seriousness over their situation back by demonstrating said arsenal's destructive capabilities as a result:
    • When he introduced his battle robot that later easily demolished Probe's original body, the robot's acronym in the Malaysian version, P.E.T.A.I, sounds exactly like the vegetable of the same name in some countries at Southeast Asia, explaining why BoBoiBoy and co. instantly had mere mention of said name at first.
    • When Ejo Jo made his return in Season 3 finale, he brought an advanced combat suit that has an even more hilarious acronym wherein the Malaysian version, it is called S.A.M.B.A.L. Because of said acronym sounds like a food condiment this time, BoboiBoi and co. understandably made fun of him for it. The humor from the aforementioned acronym was so great that even Adu Du and Probe briefly forget about their previous traumatic confrontation before that instance.
    • To maintain the humor in the English version, the acronyms of both weapons are changed into O.O.P.S.I.E and D.A.I.S.E respectively, which combined name alluding to someone who makes a mistake.
