When All You Have Is a Hammer/Playing With

Basic Trope: A character uses one power (or a few powers) for every situation.
 * Straight: Alice, a great martial artist, almost always uses her finisher techniques Dragon Impact, Phoenix Tempest, and sometimes the Starlight Explosion, to deal with her foes.
 * Alice, a powerful mage, always uses her trusty Fireball, Freeze Ray and Lighting Bolt, not much else, to fight the baddies and to solve miscellaneous problems.
 * Exaggerated: Alice beats inter-dimensional overlords, wins political debates, fixes electronic equipment and educates her children by Dragon Impacting the hell out of everything.
 * Justified: Alice sticks with what she knows, because it's worked in the past.
 * Inverted: Alice uses a wide array of attacks, and might even be a Master of None.
 * Subverted: Alice busts out a never-before-seen attack...
 * Double Subverted: ...to use as a distraction while she uses the same Finishing Move.
 * the never before seen attack fails and so she was forced to use her usual techniques.
 * Parodied: "This Magic Armor is rather costly." "Let me use my negotiation skills to get a discount!" "What? I didn't know you had diplomatic abilities" "Just watch and learn" [Alice approaches the Shopkeeper and...] "...DRAGON IMPACT!"
 * The All Solving Hammer
 * Deconstructed: Emperor Evulz fights Alice enough to where he learns all of her moves, and absolutely curb-stomps her.
 * Reconstructed: Alice protects herself from eventual curb-stomping by using all of her moves creatively.
 * Alice has the ability to gain power if someone else uses the same move as her.
 * Zig Zagged: ???
 * Averted: Alice uses a fairly wide array of attacks, but nothing too extreme.
 * Enforced: "Animation is expensive, people! Let's use as much stock footage as possible!"
 * Lampshaded: "Hey, I stick with what works!"
 * When Alice is about to finish someone off, everyone shouts "DRAGON IMPACT!" along with her.
 * Invoked: "Fear the one that has practiced 1 kick a thousand times, not the one that has used a thousand different kicks once."
 * Defied: Alice learns a new technique for a climactic battle.
 * Discussed: "Let me guess...you're going to use your Magic Blast again. Yup, called it."
 * Conversed: "Isn't Alice supposedly a powerful mage? How come she only uses the same five spells?"

When All You Have Is a Hammer, you have to go back to that trope.
