Coloration Variant:

So, I actually did this study some time ago, and even if I'm still working on my Bowser's design, I still like this study enough to share! So I added some extra notes about him and his species.

About Bowser.

First of all, in my setting Bowser belongs to a species commonly called "Royal Koopas", linked both to other Koopa species (such as Koopa Troopas) and dragons, and thus their fiery appearance, spikes and affinity to fire. They also show some feline features in addition to reptiles and dragons' ones, resembling vaguely Tarasques from French folklore.

Bowser was born on a volcanic island under the supervision of Kamek and his council of wizards. Bowser's parents gave their lavic egg to Kamek with the aim that he would rise their son in a far away land, following the tradition of letting their children grow indipendently and conquest reputation and lands without interferences. Only when Bowser will prove himself enough as a Koopa King, the Empereor and the Empress of the Koopas will finally consent to meet him.

Bowser turned out to be a total brat as a kid, stubborn, arrogant and spiteful since his first months of life (Royal Koopas grow really fast, and in the span of a year or two he was already acting like a tiny, spoiled tyrant) and Kamek genuinely considered to drop his task out of desperation. Luckily, the High Witch Kammy and various other skilled Magikoopas where there to help him. But still, harder years of Kamek's already 300 years old life.

As a teenager and in his first years of young adulthood Bowser was quite the arrogant bully, still deaf to most of his tutor(s) suggestions. He also followed the long hair fashion that was popular those years, at least until he overheard Peach talking to Daisy about the fact that she liked men with short hair more.

He has currently reached his "full-adult size". By the standards of his species, which is already massive, he has emerged particularly sturdy and tall. He stands around 3.25 meters.

Note: these infos are still a WIP themeselves, and could become outdated in the future.
