Big Damn Heroes/Tabletop Games


 * Most RPGs have you appear in the villain's lair just in time, after fighting your way past all his henchmen. This occurs even if you Take Your Time getting there.
 * It could be said that Exalted takes this to an extreme, as not only do you show up in the nick of time, but you are all but guaranteed a flashy, even gaudy entrance that defies all logic.
 * The ridiculously extensive battle history of Warhammer 40000 has hundreds of these moments on every side, to the point where in the latest Space Marine codex, Vanguard Veteran Squads have a 'Heroic Intervention' ability exclusively to pull off these moments...though it doesn't always work.
 * Though if you have them show up to help a Scout squad (the second wimpiest unit in the Codex) equipped with a teleport homer, it does always work.
 * The Legion of the Damned is an entire Space Marine chapter with this as their schtick., the surviving members of the   chapter remain loyal to the Imperium, and have since then dedicated themselves to teleporting onto the battlefield when all hope of victory for the forces of the Empire has been lost, and soundly beating the crap out of the enemy before disappearing back into the warp only to show up somewhere else.
 * Fear of this trope was the reason Horus dropped the deflector shield on his flagship at the Siege of Terra (and thus allowing the Emperor to attack him) - the entire Ultramarines legion (that's 250,000 Astartes) were on their way. The Space Wolves and Dark Angels (nearly as many marines again) were on their heels. And they were pissed.
 * Nobilis has a fairly basic power available to starting characters which ensures they always show up in the nick of time. The more powerful version ensures they ALWAYS show up in the nick of time...even if the bad guys did it 35 minutes ago, or sacrificed the princess last week.
 * In Magic: The Gathering, the aptly-named instant Dramatic Entrance lets you turn any given massive creature into your very own Big Damn Heroes.
 * There's also Avatar of Hope, which can block anything. What's so big damn heroic about it? It costs only two mana to play when you have three life or less.
 * Some cards from the Yu-Gi-Oh Card Game have effects that emulate this trope.
 * For example, Gorz - Emissary Of Darkness is special summoned when you take damage while having nothing on your field.
 * Starlight Road negates the destruction of two or more cards and special summons a Stardust Dragon from you extra deck.
 * Not surprisingly, both cards are part of the Metagame for that exact reason.
