Official Description

The purple adolescent is the youngest and most undisciplined of the triplets. Yes, someone actually figured that out... the hard way.
  Dragons: Rise of Berk  


Meeting His Adoptive Father

In the episode "Bing! Bam! Boom!", Ruffnut Thorston and Tuffnut Thorston named Bam. Like Bing and Boom, they were chased by wild dragons from Dragon Island to the sea stacks but is taken care of by Thornado on Dragon Island.

Boom's name was originally going to be Lloyd as chosen by Tuffnut but was changed by Fishlegs to make more sense. But Tuffnut still wanted his name to be Lloyd or Darren.

Answering a Distress Call

Bing, along the rest of his family, was seen among the dragons that were summoned by the Berserker Bewilderbeast during the final battle against the Dragon Hunters.

Escape from The Reaper

During the events of the Expansion "Call of the Deathsong" in the School of Dragons, the player discovers that Bing, Bam, and Boom were mysteriously locked up in the Reaper's hull. After rescuing them, both they and Thornado return to the School of Dragons to live there.

Physical Appearance

Boom shares his purple color with the wild Thunderdrum that appeared in "We Are Family, Part 1" as well as Whirlwing, who appeared in "How to Pick Your Dragon".


In "Bing! Bam! Boom!", it was shown that Bam is very mischievous like his brothers. He is also very friendly.

According to the Book of Dragons in Dragons: Rise of Berk, he is the most unruly of the three brothers.
