Mine are Sasuke, Kakashi, and Naruto in Sage Mode.
To me Kakashi is, even in simple clothes like the typical male jounin uniform, very intimidating. It's because he, as a 2D character designed like many other 2D characters, gives me that feeling that I like the way they designed the parts of him that are not ordinary and his personality. I do like his hair, though, and the fact that, in making Kakashi the way he is, Kishi has always given us a mystery to look forward to seeing solved eventually, hopefully. That mystery being Kakashi's face, because I really wanna see it. But, aside from that, the mask just makes him look interesting and I like his whole eyepatch deal with his forehead protector. I loved it especially at the very beginning of the series when we learned there was a Sharingan concealed behind it.
My biggest thing with Sasuke is the outfits Kishi gives him. He's had the most outfit changes in the series, the Sand Siblings falling right behind him, I believe, and I always like his clothes. Another funny little thing I like is that he, at some point, must've totally put some thought into restyling his bangs. Went from framing his face to covering his forehead; I find it precious. The fact that he's kept his sword this whole time also makes me smile; when I see swords these days, a glint of light on katanas in other animes, I think of Uchiha Sasuke. Immediately. Gives him a sharp look.
Naruto is my favorite character and I, naturally, love the way he looks, anyway. But the first time I saw him in Sage Mode, seriously, I fell in love. His eyes just completely change; give off a completely different vibe along with the altered appearance. Not only his eyes, but I like the attitude his entire face adopts whenever he's in Sage Mode. He looks focused and calmly confident, always. I also, though it doesn't have anything to do with Sage Mode itself, liked the cloak he wore when he fought Pein. Just saying. That's part of his character design, though only minorly.
