Diplomat is a troll, who's wandered over to the Diamond Jubilee celebrations in Varrock. He isn't very diplomatic, though, but he ate a human diplomat when he was a child, that's why he's called "Diplomat".
He just wants to eat and doesn't like peace, at first he came to eat everyone at the Jubilee, but because they were friendly, he didn't eat them, because he hasn't got friends at home. He ate them all, because he's hungry very often.
