- MadKat is the clothing and products brand of Rubius, formerly called RubiusCorp, which creates limited collections with licenses from franchises like Batman, Rick and Morty and Naruto
- The brand mixes internet culture, anime, skate and gaming with a visual universe based on a smiling cat, differentiating itself from typical content creator merchandise

What's up, folks? With the new trainers from Siroko, loads of people are asking the same thing: what exactly is MadKat? Let me break it down for you quickly and properly.
Where it comes from
- Started as RubiusCorp and ended up rebranded as MadKat.
- Its visual universe kicks off, according to the studio that designed the brand, from the face of a smiling cat with big eyes, a nod to Rubius's cat.
