Why Does Bowser Jr. Have Bloodshot Eyes In The Mario Galaxy Movie Trailer?

The newest Super Mario Galaxy Movie trailer dropped yesterday, giving fans their first look at two major newcomers: Bowser Jr. and Princess Rosalina, voiced by Benny Safdie and Brie Larson. While Rosalina’s appearance instantly won fans over, Bowser Jr. sparked confusion for one strangely unsettling detail: his eyes.

Bowser Jr. debuted in Super Mario Sunshine, typically portrayed as a fiery but charming troublemaker. However, in the new trailer, his usually bright, expressive eyes appear red, irritated, and unmistakably bloodshot—an unexpected visual change that caught the internet’s attention (h/t Kotaku).

No other character seems to share this intense, red-rimmed look, leading fans to speculate about the creative intent behind Bowser Jr.’s redesign. The trailer suggests he’s on a stressful mission to rescue his imprisoned father—a narrative choice that might explain the sleepless, strained appearance. Earlier scenes even include Bowser joking about needing eight hours of sleep to avoid “turning into a monster,” a line that now feels less humorous and more foreboding.

Some fans have pointed out that certain reptiles, including several gecko species, naturally have red eyes, meaning the choice may simply be stylistic. Whether symbolic or artistic, it’s one of the biggest talking points of the trailer.

With the movie releasing on April 3, fans are curious to see whether Bowser Jr. receives a visual adjustment—or if his “running on 30 hours of adrenaline and vengeance” look is here to stay. One thing’s guaranteed: the little Koopa prince is already stealing the spotlight.
