Roblox Catch a Monster Fusion Calculator and Tracker
Roblox Catch a Monster has become one of those games that keeps coming up in our house. My kids love playing it, but the same fusion and evolution questions kept getting shouted across the room:
How many Starlight Shards do I need for Marigon?
Then it became:
How many more pets do I need to fuse into S-rank?
After answering that a few times with rough mental maths, tabs open, and a lot of “wait, how many do you already have?”, it became obvious that this should just be a tool.
Why We Built A Roblox Catch A Monster Calculator
Catch a Monster currently does not have a quick built-in way to see exactly how many pets and materials you need for a fusion goal or evolution. You can work it out yourself, but it quickly turns into napkin math.
How many gems do you need? How many shards? How many scythes? How many more pet catches before you can finally fuse the thing you are aiming for?
The Roblox Catch a Monster tracker is built to make that easier. Pick the monster, enter what you already own, and it shows what you still need.
Plan S-Rank Fusions, Materials, And Catches
One useful part of the calculator is being able to simulate different catch outcomes.
If your luck is awful and you keep catching E-rank pets for days, the tracker can show how many more catches you would need from that worst-case path.
If the Roblox gods are on your side and you start catching better pets, you can switch the future catch rank to B-rank, A-rank, or whatever is available for that monster, and see how much faster the path gets.
That makes the tool useful for both planning the grind and comparing whether it is worth farming materials, catching more pets, or changing the goal.
What The Catch A Monster Tracker Calculates
The current version can help with:
- Owned pets by rank
- Owned materials
- Fusion requirements
- Material shortages
- Evolution material costs
- S-rank progress
- Catch-only comparisons for different future catch ranks
It is intentionally browser-based, so there is nothing to install. Your entered inventory is saved locally in your browser.

Will this Roblox Catch a Monster tracker always be available?
Yes, for as long as my children keep playing Roblox Catch a Monster and other players find the tracker useful.
