What can I call a person or a thing that is very small yet capable of defeating big giants?

I need different words that can be connected closely to this meaning.

It can be related to success,war, or anything else.

    "big giants" is a taugologism (pleonasm) AFAIK... you seldom see *"small giants" IMHO.

David is often used in reference to David and Goliath.

Story here.

Edit based on comments: They are right. It is all about context. In many contexts you would have to explain that the person is a David trying to bring down a Goliath. I have though seen the term David used alone when there is a build-up. If you were talking about someone trying to take out giants and said, "He will act like David with his slingshot..." There are tons of ways to do this. Was not implying that just simply mentioning the name David is proper, although some people would still get the inference.

    "Be careful, that guy is a real David." Who would say something like that? At least I've never heard it, I know the story and still it doesn't sound right. I would never guess what you meant.

    As @WesleyMurch pointed out, you can't really just say "David" and expect people to understand. You have to mention Goliath to give the context. "He's a David versus a real Goliath", "He's David versus Goliath", etc.

Typically means "a competitor thought to have little chance of winning a fight or contest", but modern society almost always attaches the underlying concept that the underdog is capable of beating the giants, and is in fact cheered on to do so.

  • 1
    I voted up most of the suggestions but this one stumps me. I guess people feel this meets the need but in AE underdog could mean someone who has a 49% chance of winning - so wouldn't suggest that someone with a 51% chance of winning is a giant. Then on the other side they could have a .0001% chance of winning, which implies they are going to get their ass beat almost every time. This has no meaning of beating a giant to me, it just means they are not favored. Commented Mar 21, 2014 at 14:51

Giant-killer is also used. It seems a bit on the nose, but it is used in that sense.

cf. Jack the Giant Killer.

    Or "X-killer" where X is something known to dominate its niche. For instance, lots of new cellphones are marketed as an "iPhone-killer". Lots of new games competing with World of Warcraft are referred to as a "WoW-killer".

Bantam. Bantams are small but aggressive chickens. When stringent recruiting or conscription requirements were relaxed during the First World War, smaller men were allowed to join up. They were sometimes grouped together into units called Bantam Battalions. There's an interesting wiki article on them

PS 2 of them won the VC, the highest gallantry decoration in the British & Commonwealth armies: Sgt Albert Mountain VC and Pte William Boynton Butler VC. Both men were 5'1" tall.


You could label them a Pocket Hercules.

  • where does this come from?

  • Hercules is a legendary demigod, renowned for his strength; using "pocket" as a modifier indicates that he is small enough to carry around inside your pocket, which is pretty small.

  • I dont think so, my guess mighty mouse was a take off on the other. Used in sports and politics more than 100 years. Example Miller 'Mighty Mite' Huggins brought in to help the Yankees. Because of this 1000's of products have that in their name.

A competitor, about whom little is known and who unexpectedly wins. It is same as UnderDog but still used differently.


I've heard a small but powerful or aggressive person called a "firecracker."


A "Horatio Alger hero" would seem to match your "success" case.

The Horatio Alger Hero: Ragged Dick

In Ragged Dick Alger made a homeless orphan into a hero who became the prototype for the hundreds of heroes Alger created in the next thirty years. The novel covers the hero’s transformation from a ragged, homeless boy of the streets to a respectable clerk with a salary of ten dollars per week. Dick’s fortunes improve because he follows advice, works hard to acquire an education, and takes advantage of every opportunity. He also has the essential prerequisite to success—good character. The narrator describes Dick:


His stories all were based on someone coming from improbably poor/low/hard circumstances, and rising to positions of greatness, against all the odds.

("The Secret of my Success" was a modern version of this narrative.)

  1. small but terrible
  2. Unbelievable
  3. King David

I would like to offer two different pop-culture words that work really well here too:

Rocky: Not only does he beat a giant every movie in the sense of sport but Rocky is a smaller boxer beating guys much bigger than him.

Usage - "Dude no way you are going to beat that guy. He is huge. Do you think you are Rocky?"

And on the complete opposite side of the word spectrum...

Cinderella: Just like the story Cinderella this would convey the small-time person or team that came out of no where to beat the powerful. Used in sports metaphors a lot. Used too much during NCAA tournament time.

Usage - "Wow. That high school only has 50 students in their senior class. If their basketball team wins the state tournament that would be a real Cinderella story.


I've heard a person like that described as a "dynamo"
