Inexplicable superhuman powers run in the Natzaus family, apparently. Just like his brother Arte, Piet was born with a gift neither his parents nor any else could explain. But while his older sibling posesses superhuman strength, Piet is blessed with a body that is virtually indestructible and behaves somewhat like one big piece of stretchy, bouncy rubber. Of course, this was something that had the potential to absolutely freak out other children, even more so than Arte's incredible strength (which was more of an actual, physical danger to people), so all throughout Piet's childhood he had to keep his unique gift absolutely secret.

But for someone like Piet, who likes chaos and risky things, who loves his invulnerable body and the freedom to do all sorts of insane things that comes with it, and who doesn't shy away from being the center of attention every once in a while, this was perhaps the worst curse imaginable. Only in the secrecy of their parent's home were the two brothers able to spend their free time without worrying about hiding or controlling their abilities. As a result, it is no surprise that the two brothers were thick as thieves from the start, and although they had fights often (as young boys do), they continued to be very close up into their young adulthood and beyond.

Considering Piet's special talents, he may seem at first like he would fit in perfectly at the agency, but even though his brother is an agency member, Piet has never even met Eos and his friends at all. Arte is keeping the existence of his miracle brother a complete secret from his colleagues at the agency out of fear that Piet's abilities might frustrate or depress them, just like Arte's own powers did to his former boyfriend, Sasha.

Piet likes travelling and going to scenic, exotic locations all over the world, which he documents in his popular travel blog and Youtube account. What his followers online don't know is what kinds of crazy shenanigans he gets up to while he spends time at these locations: Going for a bungee jump off the highest bridge in Europe, but without a rope, is still relatively tame on his list of favorite activities.
