Geodude. I picked Totodile and wanted something that would be super effective against Faulkner. Actually, Golem and Feraligatr were the only two Pokemon I used throughout the game, aside from HM Slaves.
My first was a Lv 2-3 Sentret, who was also the first pokemon to be in my Pokewalker, but scrapped shortly afterwards. However, I caught a Spearow in the Pokewalker with that Sentret, who is now a Lv. 55 Fearow.
the first i captured was a pidgey lvl 3 and its still in my team as pidegot lvl 64. i usually capture a flying poke early so pidgey was my first capture;bonsly; could someone trade me an arceus i have lvl 100 raikou and others
