^ The Garo themes are just awesome. Both of 'em. At least for me. The first one felt unique, and made really good powerup music. The second was well, plain awesome.
For Ultraman, I really like the first Nexus OP, as I've said. But Mebius was pretty good too. And Tiga, "Take Me Higher" is one of the most unforgettable TV show openings ever. And that's for all kinds of TV shows, not just toku.
