Who is Clara Oswald? Well it is clear that this version of her character is a shallow vacuous non-entity...The way that she suddenly turns into some kind of military commander who can handle open warfare with the Cybermen is just taking the piss. There is no sense that this kind of responsibility bothers her or makes her doubt herself; nope, she takes to the stage like General Custer and barks orders like she has been doing this all of her life.
More common in works revolving around warfare, a Mary Tzu is a character, usually a military commander, with unrealistic tactical abilities. They can pull a win out of any battle no matter how outnumbered, outgunned, or outmatched, can guess any enemy commander's plan no matter how convoluted or how little information they have to work from, and any plan they come up with will work perfectly, often employing Hollywood Tactics
, resulting in total enemy defeat and another smashing success for General Tzu's track record. As per the standard Mary Sue
traits, such a character is usually treated as a paragon and/or revered by the other characters. Sometimes they come complete with a Big Book of War
, possibly self-written.
To be clear, this trope only deals with unrealistically
good tacticians. Merely great
commanders wouldn't apply, as long as they're fallible, or if they're written well enough to make their victories seem plausible. If it looks like they play Gambit Roulette
instead of more sound and realistic plans
you've got a Mary Tzu. Another test you can do: Are the character's victories all perfect? Or do they suffer losses and pay prices? Even if there isn't a Gambit Roulette
every other victory, having plans that are unrealistically successful, such as losing no
troops who were sent in to distract heavy fire, that's also a Mary Tzu.
In some respects, one could argue that this is a case where "show, don't tell"
apply. If a character is simply described as an excellent commander, but the writer doesn't actually describe the tactics involved, it's a lot easier to accept, since the actual maneuvers can be left to Take Our Word for It
Sometimes, this character will merely be a plot device, but other times it can be piled onto the Common Mary Sue Traits
of your fourteen year old sparkly invincible teenage girl
. Those are only worst case scenarios though, as most characters associated with this trope tend to be older men (which sometimes makes them popular despite being invincible
In Real Life cases exist of brilliant strategists successfully predicting their opponent's plans, only to then dismiss their own prediction as depending on ascribing Mary Tzu-like powers to their enemy.
Named for Sun Tzu
, a Real Life
(maybe) Ancient Chinese general
whose Art of War
is still used by many militaries around the world and is considered one of the greatest treatises on warfare ever written, as well as Mary Sue
, the archetype of the unrealistically perfect protagonist.
Compare to The Chessmaster
or The Strategist
, which are for masterminds that push, but don't destroy, Willing Suspension of Disbelief
. Also see Hollywood Tactics
and Idiot Ball
as (like all Mary Sue
types), a Mary Tzu's main ability is to make everyone else incompetent so that they look good.
No examples please, this just explains the term.
