Yeah, I was under the impression that Kaeru meant Frog and change, but if it means hero, then he's totally the greatest named character ever.
And holy crap, I didn't realize there were so many Marle haters until I came to this forum. I suppose killing her off could drive Crono and by extension, the story, but Marle is what got him into this mess. Until he met her, he was just some spiky-haired kid at the fair.
I've never been a fan of Lucca or Ayla, if anyone should be offed it'd be one of them two. Of course, I'm speaking merely from the parts of the story I liked...Both characters have their advantages in battle, but CT was never challenging enough for me to get over my in-game sexism (I rarely used any of the girls in the game: my team would be Crono, Frog, and Robo, until I got Magus, thus Robo gets the boot).
And did someone mention that Magus may just simply be a title? I've always agreed with that, and I believe the re-translation supports that theory: at one point Ozzie introduces his fort as "the Great Magus Vinnegar's place" or something.
