Tommy Oliver, baddest-ass Power Ranger of 'em all. My favorite Power Ranger is the Black Ranger (Mastodon!- and I prefer Adam over Zack), but for sheer badassery you have to go for the green.
I never liked PR, I was too old for it & just saw it as a cheesy live action version of Voltron. But, my brother was just the right age for it & loved it, so I did get a lot of exposure to it growing up anyway, and have to admit that if there was one character that I did like it was him. It must be b/c he's the green guy & that's my favorite color. His dragon was cool too. I think I even still have the "morphing" figure of him too that my brother gave me!
I've always liked it, but can certainly understand why someone wouldn't. The first several seasons are terrible- almost unwatchable- when they aren't fighting. It's like a 'Highlights for Children' version of Saved By the Bell.
