Kino fight scene. One of my favorites in all Gundam. Sold me on Heero's character and it was very cool to see him use Mercurius instead of a Gundam. Wing's biggest strength imo is the directing. It actually has some good directing behind its scenes to make them more visually interesting despite its mediocre animation compared to some modern Gundam series. Despite following some UC plot beats, I think Wing really went out of its way to make something unique. Just the way the Gundams are treated as disposable tools is a big example.
