I thought Beast Wars was great cause of the humoungous cast of non-show characters. It's not that I didn't like the show, it's just that all the characters save Tigerhawk(whose fig I'm not huge on), and TM2 Megs and TM2 Black Arachnia, got properly charcterized, and I just don't feel the urge to track them down. Plus, I pretty much got most of the characters when I was a kid. The marketing worked!
Another vote for TM Waspinator. He is truly one of my favoirite Beast Wars, and the chrome or whatever they used on his eyes is pretty strong, as mine never chipped. The wings broke a few times, but that was probably due to overplay. Even then, the joints are still nice and tight.
Other non-TM's I'd suggest? Terrorgator, that is just one really cool looking guy with the gun and shield. Claw Jaw, calamar alt. modes rock

. Snapper, cause turtles are cool too. I know there are others.
TM2's that are cool: Prowl, even if he doesn't have a weapon. The hands remind me a lot of the old Marvel Superheroes Secret Wars figures. Ramulus, he's nicely posable. Optimus Minor. Don't let bad hype fool you! Get it and see your opinion! I think he's a great little basic. For balancing purporses, Scarem. Scythes for hands, awsome

. Finally, the Universe version Frostbite. This mold was meant to be a Pred, it just looks so awsome, with so many sharp spikes everywhere, a cool sword, just great. The only complaint is that the beast mode doesn't lock in.
