I'm looking for a word that means something that is powerful, unstoppable, but also fast. "Juggernaut" covers the first part, but it implies enormous size and sluggish inertia. I feel like there's a word that fits the idea, but I can't come up with it.

It's intended to be the name of vessel, so it doesn't have to be any particular part of speech.

Avalanche? Tsunami? Landslide? It feels like terms regarding forces of nature might fit your bill, but there may be other terms that are more human in nature if that is your goal.

  • Following up on that, you might look into explosions as well: blast, pressure wave, explosive etc. – Benny Bottema Jan 26 at 17:14

Meteor has been used in this context. They are not unstoppable, but they’re pretty close to it.

You could also try starting with the names of any of the larger Felidae.

However... you are not exactly the first person to face this problem, so a lot will depend on how original you want to be.


Wolverine? Badger? Honey Badger? oooo I know - fast, irascible, unpredictable, darn dangerous, large AND fast both in water AND on land - Hippopotamus!


In terms of powerful and unyielding, Dauntless has launched many a vessel.

incapable of being intimidated or subdued

-Merriam Webster

  • Hi Jimalaya, welcome to EL&U. I don't think dauntless and powerful are synonyms, but in any case your answer is too short: the system has flagged it as "low-quality because of its length and content." An answer on EL&U is expected to be authoritative, detailed, and explain why it is correct. It's best if you edit your answer to provide more information - e.g., add a published definition of dauntless (linked to the source) and examples of its use. For further guidance, see How to Answer and take the EL&U Tour :-) – Chappo Jan 23 at 7:29
