i first watched sakura cardcaptor and avatar the last airbender which i think is technically an anime, but it was after i watched inuyasha that i really got into it. although now i watch it and it looks sorta childish compared to some i've watched recently
Any anime that was on Toonami and Fox Kids back in the day. But it would have to be Yoroiden Samurai Troopers/Ronin Warriors that made me look up stuff on the net. Then Sailor Moon. Now it's whatever I find.
