Awesome but Impractical/Fan Works

"A flashy feature that has limited usability for victory."


 * In Aeon Natum Engel and Aeon Entelechy Evangelion the Military views the Evangelions as unnecessary large Engel-prototype relics from the past. In the latter this view is somewhat extended to the conventional mecha, at least by the tank crews.
 * BlackMegaGargomon from the Tamers Forever Series has an unbelievably powerful technique known as the Black Moon Flare, which causes unfathomable amounts of devastation within a vast radius. Unfortuneatly, the technique happens to be a little too powerful, and D.C is only ever able to manage one use of it.
 * In Calvin At Camp, Calvin, Jason, and Marcus try to attack Kevin with medieval weapons, but find out the hard way that although the weapons look cool, they are impossible to lift.
