UC Era Gundam from 0079 ~ 0100. The day Zeon surrendered is the day UC ended for me. I don't care much for F91 or Victory.
Nobody, and definitely no antagonists in subsequent series (AU or otherwise) had the flair Zeon had. They were truly good antagonists.
Besides, you will never get this:
Turn A - Truly enjoyable. It was a Gundam series with heart, and lots of it. Too bad audiences couldn't be more receptive to the titular Gundam.
SEED/DESTINY - Lots of likable characters here. Its unfortunate DESTINY suffered the way it did.
00 - Despite having a
wooden hero, other characters and the plot make up for it. Oh, the movie was good too. It was a very well depicted last stand.
- Tak (And, here is hoping Sunrise would animate Gaia Gear)
