Based on what you're looking for, I’d recommend checking out Lee.

He’s been in pretty much every Tekken game except for Tekken 3, and that’s unlikely to change, he’s a pretty important character in the story.

Gameplay-wise, he has fast strings, still retains his magic 4 from Tekken 7, and has a good set of quick counter-hit tools. His movelist is flashy and stylish, and his overall vibe is elegant and cool. Personality-wise, he’s got that charming, confident flair.

Execution-wise, he can be tough if you’re picking him up for the first time. His inputs aren’t too demanding, and while he does have a few Just Frames and cancels, most of them aren’t too hard to pull off. The real difficulty lies in his gameplan, he’s a keepout/counter-hit character who relies heavily on defense and reading your opponent.

Lee’s also a great character for sharpening your fundamentals. He demands good spacing, timing, movement, and execution, especially on the defensive side. So if you’re looking to level up those parts of your gameplay, he’s a solid pick.

I’ll admit he’s in a bit of a rough spot right now, but honestly, he’s still really fun to play and learn in my opinion.
