What metaphors are used in In Pharaoh's Army: Memories of the Lost War by Tobias Wolff?

Metaphor:

"My father was Toad. He wasn't playing Toad, he was Toad, and not only Toad, the audacious, Toad the shameless and incorrigible, but, as the story gave occasion, good-hearted Toad, hospitable Toad, Toad for whom his friends would risk their very lives."
