Monstrous Physique — Bowser

We are keeping things classic this week. Over the last few months, I’ve been playing Super Mario Odyssey. The series’ villain, Bowser, seemed like the perfect candidate for stating up. He’s a big scary lizard and I know that those always serve as great monsters. Let’s-a go and have a look at Bowser!

This enormous lizard stands on two legs. Its large shell is covered in spikes and its arms end in terrifying claws.

Koopa Klaw (Ex) If Bowser successfully maintains a grapple, he can inflict damage and then throw the held creature into an empty square within 10 feet. The thrown creature is knocked prone unless it succeeds a DC 17 Reflex save. The save DC is Constitution-based.

Bowser, also known as King Koopa, is a monstrous creature from a faraway kingdom. He is an enormous creature which resembles a lizard or dragon known as a Koopa. From his personal castle, he plans assaults against the citizens of a neighboring kingdom, the Mushroom Kingdom. On many occasions, Bowser has even kidnapped the ruler of the Mushroom Kingdom, Princess Peach Toadstool, only to have his plans foiled time and time again. Although he has failed countless times, Bowser remains a formidable creature. He is able to breath flames and throws his foes around with great ease. Rumors hold that Bowser holds within him the power to unleash a monstrous force capable of empowering him to cause great destruction, but few seem to truly believe this to be the case.

Monstrous Origins

Bowser is a actually a scary fellow, when he’s not driving go-karts or playing sports. As with a number of great Nintendo icons, I turned to Super Smash Bros. to help me determine Bowser’s abilities. The obvious thing is his bite and claw attacks as well as his ability to breathe fire. In order to make things more interesting, I decided to “port” over his Koopa Klaw move from the games which lets him toss his opponents aside after grabbing them. As a whole, the stat block is very simple, but that’s Bowser in a nutshell, as well. He’s a simple villain with simple plans that is simply fun to beat. I added a nod to his Giga Bowser form from the Smash Bros. series, which is a surprisingly terrifying upgrade to the Koopa. I would consider stating Giga Bowser up as well, but it would mostly just be a larger version of this Bowser. For anyone that wants their own Giga Bowser, I would recommend increasing his size to Huge, upping his HD to about 15, increasing the size and damage of the breath weapon, and possibly giving his claw attacks the options to automatically add Awesome Blows. Maybe you can throw on the kaiju subtype for good measure!

That’s it for this week! If you end up introducing Bowser into your game or you have any request for a future Monstrous Physique, please drop me a line at
