Alex Kidd Magnet

Many centuries ago, on the planet Aries, there lived a boy named Alex Kidd, for seven years alone on Mount Eternal, where he studied and trained in the Shellcore technique, an ancient art that makes one strong enough to break rocks into pieces. This technique enables an Arian to alter the size and toughness of his fists through sheer willpower, and enables one to shatter rocks with one's bare fists.
