Luvdisc are often thought of as a symbol of love, and often exchanged by lovers in Hoenn on Valentine's day, but they are often derided as a poor choice for this honor. If Luvdisc represent the power of love, then love must be a weak and brittle thing, something demolished at the first sign of adversity, for Luvdisc are among the weakest of all fully evolved pokemon in battle.
Certainly there are plenty of cynics in the world who think that to be exactly the case, but they are never the ones giving Luvdisc to their desired soulmates. Yet as long as Luvdisc have been exchanged, poets, authors, and dramatists have poked fun at their utter weakness in battle, and many a broken-hearted trainer has berated their Luvdisc after a bad breakup for being completely useless.
To their credit, it must be remembered that the Luvdisc did not choose to be symbols of love, but were chosen to be one by humans. And although they are weak in battle, battle need not be the only thing a pokemon is good for. Luvdisc are pokemon who possess long natural lifespans, are adept at escaping predators, and although washed away long distances in the rain, will always return to their trainers. And their heart-shape scales have the power to evoke memories in humans and other pokemon, strengthening them by bringing back techniques and passions that they should never have forgotten. Love, like the Luvdisc, can be a wonderful thing, but is of little use when expressed on the battlefield.
