Finally, Roto Grip decided to call bowling balls after nutorious villains of the Marvel comics! We hope to test out Doctor Doom, Magneto, Venom (oh wait, Motiv already did that) and, of course, the Kingpin in the future, but now we will start with the new Gremlin! This latest addition to the HP3 line was born from experimentation, and the result is a clean, angular, and a little chaotic backend reaction that fills a very specific spot in your bag. In this Roto Grip Gremlin review, we’ll cover what makes the Gremlin stand out, how it performs on medium oil, and whether it deserves a spot in your arsenal.

What to Expect from the Roto Grip Gremlin?
The Roto Grip Gremlin features the new Rondure MaxD Core. Roto Grip increased both the core and slug densities to raise the RG and differential while slightly lowering the intermediate diff. This creates a clean look through the front and a sharp, controlled move at the breakpoint.
Wrapped in the brand-new V-R1 Pearl Reactive coverstock, the Gremlin offers a fast response to friction. The factory Power Edge finish helps it glide through the heads and snap hard off the dry - something rare for asymmetric pearl balls with this much control.
If you’ve ever wanted your big asymmetric ball to transition cleaner and finish harder, this one fits the bill. The Roto Grip Gremlin review wouldn’t be complete without saying - it really fills a gap many bowlers are looking for.

On-Lane Performance: Roto Grip Gremlin Review
The Roto Grip Gremlin shines when the front part of the lane starts to burn up. It gives you angle and power when earlier balls lose their edge. This makes it a great choice for medium to medium-heavy oil, especially during lane transition.
We found the Gremlin to be:
- Clean and quick through the heads
- Strong off the dry
- Angular but still predictable
Thanks to the V-R1 Pearl cover, this ball feels more forgiving than most asymmetric pearls. Even with its sharp backend, you still get control.
Who Should Use the Roto Grip Gremlin
The Roto Grip Gremlin works best for bowlers who:
- Need a clean, strong option for medium oil or transition
- Prefer angular motion without needing a ton of oil volume
- Want a reliable asymmetric pearl that moves hard off friction
If you’ve thrown the Storm Equinox or Storm IDentity, this ball fits a similar role—but the Gremlin brings its own unique blend of sharpness and control.
In this Roto Grip Gremlin review, we think it’s the ideal “bridge” ball between your heavy oil hook monster and weaker pearls.

Roto Grip Gremlin Review – Pros and Cons
Pros:
- Very clean through the front
- Strong and angular on the backend
- More affordable than Equinox or IDentity
- Bold colors and logo help it stand out
Cons:
- Might be too clean for fresh or heavier oil
- Could feel too sharp for players who prefer smoother shapes

Final Thoughts – Roto Grip Gremlin Review
The Roto Grip Gremlin brings something fresh to the HP3 line. It’s clean through the front, hits hard off the spot, and adds control without losing shape.
It also costs less than similar asymmetric pearls from Storm, making it a smart pick if you want performance and value.
If you're hunting for a strong pearl that looks good and plays even better, the Gremlin should be high on your list.
