Dragon Ball Super: Broly officially made Broly a part of the series canon with a new background, design, and personality from series creator Akira Toriyama. Although the film provided an explanation for Broly's new look, some were left for fans to find out, and now, a fan has discovered a surprising connection between the adult Broly's new look and Beets.
As @InfernoDBZ pointed out on Twitter, the fact that Broly wore a pair of pants when he was discovered on Vampa was left unexplained but since Paragus killed Beets when it was clear that the three of them were going to be stranded on Vampa, he removed the clothes of the dead Saiyan and later gave the pants to Broly.
The green fur around Broly's waist is also explored in the film. Broly explains that his fur came from one of the giant monsters on Vampa. He became friends with a creature named Bah but one day, Paragus shoots off Bah's ear, and since then, Bah no longer trusted Broly so Broly kept Bah's ear around his waist as a reminder of the friend he used to have.
