I like the cries of a lot of pokemon, so it's kind of hard to remember all of them. Some that stand out to me are: Gothitelle, Victini, Trubbish, Virizion, Espeon, Froslass, Suicune, Mew, Mewtwo, Musharna, Swoobat, Maractus, Archeops, Rapidash, Articuno, Lugia, Lumineon, Glaceon...
..Yeah...
I used to know all of the cries of the first 150 pokemon -- I even knew which ones had the same cries, like Aerodactyl and Vileplume. I kind of gave up trying to memorize all of them after the original games, but I can still recognize most pokemon by their cries alone. =)
