Geodude is a Pokemon from the original 150, and one of my favorite starting rock-type pokemon. Obviously he has to evolve to do much good later in the game. But for a Pokemon that's easy to find, he's not bad.
His Japanese name is イシツブテ (Ishitsubute) which combines the words 石 (Ishi) which means "stone" and 礫 (Tsubute) which means "throwing stones". So literally he's a rock throwing stones.
