STARFLOWER!
I went with Star Flower because she has:
1. A good pose
2. A beautiful blue body color
3. Nice, big eyes.
4. Pretty hair colors, with that nice bright green.
5. Coolio name reminds me of the G1.
6. Her symbol close-up is very intricate and pretty.

I don't have anything against Comet Tail, but frankly when I saw her in stores she just wasn't impressive enough for me to even shell out 5 bucks for.
Anyone got a close-up of Star Flower's symbol?
