I think any character is relatable in some way, it just depends on your own personality and experiences though. Unless you're Rune, who is a cyborg intent on taking over the world :p.
Nah, just kidding there Rune, I can understand what you mean as I mostly just keep to myself by choice, though it's a choice I make because I feel I wouldn't really fit in anywhere. I've started eating with a group during lunch simply because we all share an interest in Yugioh, but I am simply too different than them in several other ways to feel comfortable around them. Or to call them my friends.
