Ultra Kaiju Monster Rancher Fusion Compatibility

 Check out the Tutorial!  The Fusion calculator can help you plan for and achieve the best fusions for any Kaiju, or simply see what two already raised Kaiju might produce. Save and load individual Kaiju, or your progress, your favorite fusions, and share them with others!

Tutorial: How to use Fusion Calculator

Ultra Kaiju Fusion Calculator explanation

The Research Center is Locked initially. Beat D Class official and acquire Breeder Rank 2 (R-2) to gain access.

How to determine Stat Gain Offsets

Use  Keyword Solver  or  Keyword List  to determine if the Keyword you used will create Stat Gain offsets. If they do, you can adjust the Stat Gain in the Fusion Calculator by double clicking the Gain Letter.

How do I use this to get a baby Kaiju with high stats?

The column you can enter numbers into are the Stats you raised with your monster. The column to the right of it, is a hidden modifier applied to the stat during combining which is based on a given monster's Stat Gains. The Stat Order (used to check compatibility) is determined by this modified value.
I have 2 raised Kaiju
Will they make a good Baby?
  1. Select the Main and Sub breed for both parents.
  2. Enter in the raised stats for both Kaiju.
  3. In the Predicted Result section, Click through each result.
  4. Combine Kaiju 1 and Kaiju 2. Refer to "Save Scumming Breed outcomes"
    below for getting the Fusion result on a given week.
Without planning ahead, you may not have any good results.

There are multiple variants with different gains.
Refer to the Monster Data to
determine which version you used, and
Adjust the Stat Gain letters if needed.

I have 1 raised Kaiju
What should I combine it with?
  1. Enter the "Fully raised Kaiju 1" stats for Kaiju 1.
  2. For Fusion Kaiju 2, Click "Suggest Kaiju 2" button.
  3. Click "Use as Kaiju 2" for a desired Kaiju
  4. IF you want a Lazy Fusion, click "Use Base Stats" button.
    • You may still need to raise/lower a stat to align
  5. IF you want an optimized Kaiju 2, Click "Optimize Stats" button.
    • If needed, use "Scale Down" button for something achievable.
    • You can also raise just a stat or two for a "lazy fusion"
      that will still yield higher than normal stats.
  6. Click through the Predicted Result table to
    determine which Kaiju you want to combine for.
  7. Combine Kaiju 1 and Kaiju 2. Refer to "Save Scumming Breed outcomes"
    below for getting the Fusion result on a given week.

There are multiple variants with different gains.
Refer to the Monster Data to
determine which version you used, and
Adjust the Stat Gain letters if needed.

I have 0 raised Kaiju
I want to start from Scratch!
  1. Choose ANY Main and Sub that can yield a Target Result baby you want.
    • For the highest Stat bonuses The Target Result will need
      to be as low a % chance as possible.
  2. Click "Optimize Stats" button after choosing each parent.
  3. (Optional) Use "Scale Down " buttons until they're at
    levels you believe you can raise stats to.
    • You can still fine tune stats manually as long as the
      Stat order stays in the same order after optimizing.
  4. Raise Kaiju 1 and 2 with the indicated stats after Optimizing/Scaling.
    • There are multiple variants with different gains which won't work.
    • Refer to the Monster Data
  5. Combine Kaiju 1 and Kaiju 2. Refer to "Save Scumming Breed outcomes"
    below for getting the Fusion result on a given week.

There are multiple variants with different gains.
Refer to the Monster Data to
determine which version you used, and
Adjust the Stat Gain letters if needed.


Choose your parents and input their stats to see if they align for stat inheritance.
You can adjust the Stat Gains to a given variant as needed (Important for calculation!)

Note the Stat Order: LIF, POW, INT, SKI, SPD, DEF

  • GREEN indicates the Stats align, you should get bonus stats on the baby.
  • RED indicates no alignment and you should get near baseline baby stats.
NOTE!!! Exact same parent Kaiju look mathematically compatible, but they will not work.

Dona's Messages

  • 6 Stats align: "This is wonderful! I can't wait to see how this turns out."
  • 4 Stats align: "That looks like a good compatibility. You can expect something good."
  • 3 Stats align: "Not bad. I bet the result will be pretty good."
  • 2 Stats align: "Not bad, but not great either. A mediocre combination, I'd say."
  • 1 Stat aligns: "That's poor compatibility. I can't recommend this."
  • 0 Stats align: "Hmmm, not sure about this combination. But hey, I'm not going to stop you."

Basic Fusion information

OF NOTE: There is a counter that is decremented. It's value is semi-random (>1) when the game is loaded. After resting or passing time, it is decremented along with all the random numbers being regenerated, if the counter gets to zero, then another random number regeneration occurs. Because of this, it is impossible to predict a date on which a fusion percent will yield a specific Kaiju, but it is why you will always get the same Kaiju on a specific date when resetting to try again on the same week.
  • Kaiju 1 should have the higher stats/techs when combining.
  • Stat orders of Parents are considered for stat inheritance. Baby's Stat order is not considered.

Optimizing Save Scumming

Perform your save scumming in this order. Doing so in this order should allow you to get every aspect of your desired outcome. each step in this particular order ensures the previous step is retained.
Baby > Likes&Dislikes > Techs.
  1. Figure out which Target Breed/Baby you want from Fusion, and use the Breed Outcome method below to figure out which week will give you the breed you want. Save on this outcome week.
  2. Get the Likes/Dislikes seeded for this particular week by using the Likes & Dislikes method below.
  3. Get the Techs you want by using the Tech Outcomes method below.

Save Scumming Breed outcomes

Outcome is locked into the current week/save point, but seems to make that determination when rolling into that week.
  1. Save on a given week just to have a permanent save beforehand, then attempt the fusion. If it's not what you want:
  2. GO to Title Screen & Load from the AUTO save spot, and progress 1 week forward (Use a junk monster to pass the time with 0 cost food & Rest)
  3. After progressing 1 week forward from the previous fusion week, Try Fusing again.
    • This means if you don't get want you want on say.. Week 1, you'll try on week 2, then week 3 etc.
  4. REPEAT steps 2 & 3 until you get the desired outcome. (It could take a year or more for very low % outcome)

You can stop here, or prepare for more save-scumming on this specific week. You can skip over the next section or, if you want to continue:
If you have the set week for the Breed outcome you want, now you can continue to refine other aspects of your monster if you want to...

Save Scumming Likes & Dislikes

  • On a given week, you can seed the Likes and Dislikes of Kaiju by Generating a Kaiju at the Altar.
  • Once a Kaiju is born with preferable Likes and Dislikes, you can stop here and Fuse your preferred monsters that should be born with the Likes and Dislikes.

With the week set for the Target baby, and the Likes/Dislikes seeded for your planned Fusion, If your Parent 1 Kaiju has a lot of techs to pass down, you can prepare for the last step in save-scumming.
This last step should retain the saved seeds from above and allow you to re-roll for the desired tech load-out assuming you have a number of techs to be passed down.

Save Scumming Tech Outcomes

  • Tech inheritance can still be randomized with traditional Save/Load:
  • Save the game on an available save slot, and Fuse. If the tech loadout is undesirable, load the save and try again.
    • Special techs are not inherited
    • ~60% of non basic techs can be inherited
    • Or 1 of each Tech Type if the baby main doesn't match Parent (1?) main.
