Bowser is a huge, yellow, burly, green-shelled Koopa with spikes, horns, and red hair. His bushy eyebrows and mane are fittingly a bright, fiery red-orange and he has bright red eyes. He sports two small horns, many spikes on his shell with brown-orange spike-rings, as well as along his tail (minus the spike-rings). He wears several spiked collars around his neck and arms. He has three claws on each of his massive feet, which support his impressive girth. He has three claw-tipped fingers and a thumb on each hand, and his arms are noticeably burly, indicating his vast physical strength. While his face and his shell are green, his underbelly and snout are flesh-colored, and his tail and limbs are an orange-tinged yellow.
As mentioned above, Bowser is a member of the Bad-Anon support group. When Wreck-It Ralph expresses interest to not be a bad guy anymore, Bowser reacts in shock by breathing fireballs.
- Bowser did appear in the arcade game Versus Super Mario Bros., which was essentially a mix of levels from SMB and the Japanese Super Mario Bros. 2 (later known in the US as The Lost Levels). VSMB was seldom featured in American arcades, so including Bowser is something of a stretch in a film designed as an homage to arcade games.
- He is the only Mario character that appears in the movie. The Super Mushroom makes an appearance in the Lost and Found in Tapper's.
