Oh wow! Tenchi Muyo! Now that's an anime show that brings me back to them good ol' days.
Everyone has their "first animes..." that gets them into it, and I'm no different. However, it was Sailor Moon that ended up being the show that introduced me to anime. It was the reason that got me tuning in Toonami back in 2000-2001ish. But.... Tenchi Muyo, being the second show, was THE ONE that got me hooked and made me a fan of anime (and made a fan of every type of animation later on, rediscovering cartoons I watched as a kid, like Aladdin). Anyway, it was the story, the characters, their adventures, the music, animation, everything! This show really drew me in with an array of female characters that interested me (even moreso than any of the ones in Sailor Moon). By the time I watched the OVAs, the 1st TV series (Universe), and even the 2nd TV series (Tenchi in Tokyo) off of Toonami, I wanted to go through the whole adventure again. Even to this day, its still one of my most favorite anime series.
I was going to list everything out, but soundmonkey44 and others before described everything better than I could.
You know, as silly as those digi-bikinis are, I always though the one they put on Ryoko looked best. Purpleish-spectre blue seems to look really good on her. At least she had one that looked good on her. It kept reminding me of No Need For Swimsuits episode of Tenchi Universe...
Well, it may not be one of the girls, but I always thought Kagato's english dub voice (both versions since they're voiced by the same actor) was sexy. To me anyway... >.> He just had that deep, silky, and smooth villain voice (kind of like Jafar's voice). Okay! I admit it, I bit of a Kagato fangirl (for some reason, I slightly prefer Universe's version, maybe its his green hair...).
