Monstrous Physique — Bowser (PF2E)

We are keeping things classic this week. I felt like taking a look at the various characters from the Super Mario games for this blog and decided to start with the big King of Koopas himself, Bowser. 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!

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.

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
