i am betting that kingcharizard is johnny rolo and he's sad that no one rated his jank stall team.
anyway, the most common leads are raikou, zapdos, jolteon, forretress, and cloyster. keeping that in mind, just use one of them, or a pokemon that beats all/most of them.
snorlax can make for an interesting lead. in fact, the set body slam, earthquake, fire blast, selfdestruct was referred to as "starterlax" because it was intended to beat all of the common leads. i guess cloyster wasn't so common at the time. that isn't the only set you can lead with though obviously, and you don't have to lead with it if you do choose to use that set, but it's a fine choice. lovely kiss makes it a decent lead as well. speaking of which, nidoking is a good lead. he was better before bitch hp legends were unbanned because now zapdos stands a good chance of beating him one on one. other pokemon with sleep moves are fine. anything that will scare off or take advantage of the common leads i mentioned before will do nicely, but don't use something that doesn't do anything immediately threatening like a wimpy, punkass steelix.
charizard is bad because it cannot do anything without belly drumming. the only lead it is good against is forretress. if you lead with charizard and they ARE leading with forretress, you'll probably just be met with starmie or suicune or zapdos right away anyway. don't do it. and aerodactyl is one of the shittiest pokemon there is.
