Character Love Meme

In a rather hopeless effort to prove that I am not always a terminally grumpy old sourpuss who angsts about everything, I've stolen the Character Love Meme from lyras.

Name a character from one of my fandoms, and I will write no more than 100 words on why I love them.

So - name your characters! Fandoms: Harry Potter, A Song of Ice and Fire, Star Trek: Next Generation, Star Trek: Enterprise, Robin Hobb's Farseer and Golden Fool series, Alastair Reynolds's Revelation Space quartet, (a lot of, but not all) Terry Pratchett, Lord of the Rings, Mina de Malfois.

No reasonable (or unreasonable) offer refused...
