It's What I Do

"Leonard: "You betrayed us for money!"

Sheldon: "I'm a Rogue Night Elf; don't you people read character descriptions?""

- The Big Bang Theory

Characters are the sum of their tropes. Sometimes the Genre Savvy even recognize this about themselves. When another character makes a comment about their behavior that fits their character, they will usually respond with something like, "It's what I do."

Can be used in several ways:
 * 1) A comedic "Duh!" moment, which is most often.
 * 2) A Tear Jerker when they perform a Heroic Sacrifice.
 * 3) A villain berating the heroes for actually expecting something different from them.
 * 4) A Jerk Justification

An implication with using this line is that characters need to be consistent in their behavior, not just doing whatever is needed for the plot. But don't be too surprised if characters behave in a way slightly different than you expect, as an Out-of-Character Moment can be the opposite of this.

The underlying implication is that the character doesn't necessarily WANT to do whatever it is they're doing, that it's not a special case just business as usual. It's their nature and they can't help it. Can express a desire for emotional growth, or the lack thereof if "What I Do" is something the character has spent a significant amount of time trying not to do, or angsting over doing it.

Or, in the Type 2 case of a heroic sacrifice, the person being saved is someone who arguably doesn't deserve to be saved. The hero is expressing that it doesn't matter if the victim deserves to be saved; a trademark of someone suffering from Chronic Hero Syndrome. To not be the hero is unthinkable. However, since these heroes are very rarely stabbed in the back immediately after taking the bullet for a nemesis... well, maybe the victim did deserve to be saved. This situation lends itself to many a Heel Face Turn.

Comic Books
"Batman:Joker, why?
 * Wolverine: "I'm the best there is at what I do. What I do ain't very nice."
 * Deadpool: "Now I'm better at doing whatever it is Wolverine does!"
 * Batman (specifically, Gotham Adventures #60):

Joker: Why? Why? Because this is how it is isn't it? I do terrible, crazy things and you act all grim and gritty and stop me. And I go back to Arkham and you go back to doing whatever it is you do when I'm not around. Brooding all by yourself in the dark I suppose. That's just how we are. Or how we've grown to be. And it's never going to change."


 * Detective Comics # 823 has Batman trying to help Poison Ivy, before discovering a recording of people she tortured and killed. When he yells at her for it, she just acts amused that he's angry because he should know who she is by now.

 * In the Sci Fi channel TV movie The Fallen Ones, the Big Bad is a fallen angel who wants to destroy mankind with an army of Nephilim giants. The about-to-be-killed The Obi-Wan gives him a "The Reason You Suck" Speech, pointing out that such an event is mentioned nowhere in the Bible or in any prophecy, and the Big Bad's entire plan is doomed to fail. The Big Bad simply replies "I have to try. It's what I do." At the end of the film, in an Ironic Echo, the hero says the same thing to the Big Bad after the Big Bad tells the hero that he couldn't possibly stop him.
 * In Hobo With a Shotgun, Ivan walks around in ice skates to make his kicks deadly. Slick notes, "You're going to ruin your skates." Ivan smiles broadly and replies, "I ruin everything!"

Literature
""It's neither reason, nor logic. I'm a scorpion; it's my nature.""
 * Lighter Than Some, a Covenant Engineer in the Halo novel Contact Harvest, was ridiculously friendly. When pressed by a human-made AI on why he was helping her, he would simply reply "Lighter Than Some," which she figured meant "I help because that is who I am."
 * Helps it was also
 * In Stephen Donaldson's Mordant's Need, one of the heroes keeps getting into duels with the Big Bad's chief swordsman. He pauses to ask the swordsman why he doesn't simply overthrow the Big Bad (who is portrayed as an essentially impotent dupe of his supposed underlyings.) The swordsman replies with this trope.
 * Evil Lord Harry Dread, from The Last Hero, allies himself with his enemies the Silver Horde for one last adventure..
 * Another Discworld example is Dr. Hix, the head of the department of Post-Mortem Communications, in Making Money and especially in Unseen Academicals. It's his job to be "evil" because of his department, so whenever he does something underhanded or says something nasty he points this out, often indicating his official skull ring. (Most of the things he actually does are poodle-poking at worst.)
 * Lord Vetinari is also known to occasionally remind people that he's the Tyrant when they protest that he "can't do this!"
 * In the fable "The Scorpion and the Frog," the titular scorpion asks the titular frog to carry him across a river. The frog is afraid of being stung, but the scorpion reassures him that if it stung the frog, the frog would sink and the scorpion would drown as well, so that wouldn't be logical. This sounds reasonable to the frog who agrees to take the scorpion. But halfway across the river the scorpion stings the frog anyway, and as they both sink the frog asks why the scorpion did it, and the scorpion replies:

""I've never NOT stung.""
 * Alternate quote from the scorpion:


 * Averted in the Clan Scorpion Splatbook for the Legend of the Five Rings role-playing game, the scorpion's reply to the frog is, "I can swim."
 * A similar fable involves someone bringing a snake inside, or putting it inside his shirt, to warm it up, only to be bitten by the snake. In some variations the snake talks, and replies to the human's surprise with "You knew I was a snake when you brought me in." It doesn't reflect very well on snakes.
 * In Codex Alera the Vord Queen explains this as her reason for trying to destroy Alera. It appears to be a genetic imperative for the Vord to destroy all other species. She also offers the same excuse to

 * From the Doctor Who special "Voyage of the Damned".

Rickston Slade: No.

The Doctor: In that case, allons-y."

"Romana: I don't think we should interfere.

O'Neill: It's what I do."

"Marlowe: Hey, it's what I do. It's what I do. It's what I do."
 * In the Show Within a Show Wormhole X-Treme, this is the O'Neill-a-like's signature line, which the actor practices:

"(reading about himself) "He says 'That's what I'm talking about' too much... but sometimes that is what I'm talking about...""
 * In another episode ("The Other Guys"), SG-1 is trying to escape a Goa'uld, and hesitate when they learn that the Stargate is guarded by a lot of Jaffa. The scientist with them points out, "But you're SG-1!" Though the trope name goes unsaid, the looks on the team's faces clearly imply it. And their actions cement it.
 * Episode "Revelations": O'Neill agrees to help the Asgard while Hammond and Carter still argue over it with the explanation: "It's what we do, isn't it?"

 * Turk has been known to say this in more than one occasion: "Well you know I do what I do what I do what I do."

"Ecklie: "I'll have our public information officer contact his counterpart at the station. We'll also call Judge Anderson and get a warrant for the memory card, any copies, and the name of their source."
 * Star Trek Voyager had this in a story told by Chakotay "Scorpion" relating to how the Borg can not be trusted in an Enemy Mine situation because "It's my nature."
 * Later in the same episode, both Chakotay and Janeway are shocked to find out that it was the Borg who started the war against Species 8472. Almost as if they expected something else from the one species known to attack and assimilate everything it encounters without exceptions? Duh!
 * CSI: Ecklie, former less-competent CSI and now head administrator, has always been a thorn in the team's side, but as administrator he gets actual moments of respect, like this one: Catherine had a memory card of evidence photos stolen from her and been grilled earlier by Ecklie for it; the photos appear on the television news.

Catherine: (surprised) "Thank you, Conrad."

Ecklie: "It's my job.""

"Xander: I never said you were gonna die! I implied that you were gonna die. It's totally different.

A few scenes later, after taking out four guys by himself in the time it takes a bag Hardison dropped to hit the floor, Eliot turns to Hardison, and smiles.

Eliot: That's what I do."

"Maggie: You can't just make somebody do what you want them to do.
 * Later, in the season finale, we get:

Eliot: Whoa!

Hardison: T-That's what we do. I mean...
