    About

    Catzilla adds a giant kaiju cat that players create by extracting uranium from ore deep in the bedrock zone and feeding it to a cat. To tame the transformed creature, players knock it out with explosives and feed it large quantities of uranium; once tamed, it can be ridden, healed with uranium, and bred, and it sleeps at night. Ridden Catzilla can swipe, sprint into a tail spin, roar to knock enemies away, and unleash an atomic breath that damages and destroys what it hits. Taking damage builds rage, which can eventually make Catzilla eject its rider and enter a radioactive frenzy before collapsing into a vulnerable hibernation. Six special items obtained by killing an untamed Catzilla can transform another Catzilla’s identity, changing its abilities and basic stats; documented forms include the 1954 variant, Burning, Tremorzilla, Legendary, Shin, and 2000. These forms offer distinct traits: 1954 blinds foes with faster-damaging atomic breath, Burning sets targets alight and can unleash a wide-area shockwave, and Tremorzilla charges forward while trading speed and breath range for impact. Legendary can grab nearby creatures for a powerful atomic-breath attack, while Shin is larger, tougher, and regenerates health with a three-stage breath; 2000 is faster and can combine its tail spin and atomic breath, but deals less damage with ordinary attacks.

    Security

    Not checked yet

    We have not checked its files for recent Minecraft versions yet.

    Why we show this: a mod runs on your computer like any program, so harmful code in it can take your accounts or files. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: malware means no grade, and a Warning in a latest file for a recent Minecraft version lowers it.

    How we checked · Not checked yet
    • FilesWe download the files from Modrinth or CurseForge and look at what is inside them and what their code can do, without running them. Fixed rules tell what is harmful.
      1 latest file, for a recent version. Recent versions: those released in the last 2 years, plus 1.20.1 and 1.21.1, among the most played in modpacks. 1 of them is not checked yet. See each file in Releases

    Privacy

    We have not read its code yet

    What it sends is not known yet.

    Why we show this: a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.

    How we checked · Code not read yet
    • Files readWe read the code without running it. We list each web address the code contacts while you play, and what it sends. Code that is never used is left out.
      None yet. See each file in Releases

    AI

    No sign so far that AI was used to make it

    We looked for AI tools in its texts and found none.

    We have not read its files, images and sounds yet.

    AI in the game: not checked yet

    We have not read its code for AI yet.

    Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.

    How we checked · 1 place read
