Broly is one of the most powerful warriors in Dragon Ball, infamous for his incredible strength and distinctive appearance, characterized by his green hair and striking yellow eyes. However, many fans may not be aware of Broly’s initial appearance in the anime. His debut occurred during the Other World Tournament, where he was seen in the audience while Goku battled Pikkon (another warrior from a different universe) in a martial arts contest under the heavenly arena.
The Other World Tournament arc aired in the anime from episodes 195 to 199. During the battle between Goku and Pikkon, viewers can spot Broly in the audience, making a fleeting appearance just before he transforms into his legendary form once again.

Broly’s brief cameo during the Other World Tournament went unnoticed by many Dragon Ball Z fans, as his appearance was quite quick and subtle. However, for dedicated fans who pay attention to the smaller details, this moment serves as a hint of the character’s eventual official debut in the franchise, which was released in 1993.
It’s worth noting that Broly’s fleeting appearance in the Other World Tournament is not considered canon, meaning it does not exist within the Dragon Ball manga storyline. Nonetheless, it is intriguing to see how the creators of the film franchise envisioned this character.

Broly’s first significant appearance in the Dragon Ball universe occurred in the film “Dragon Ball Z: The Legendary Super Saiyan,” released in Japan in 1993. In this film, Broly is portrayed as an extraordinarily powerful Saiyan, harboring deep-seated resentment towards Goku and his family.
