I don't know if any of these items will be useful later in the story, but eventually Pulse and team will have a trophy room of their own. Annie might have one for just herself someday, but she'd have to be B-Class to be a solo hero, and that could be a long time in the future.
Oh yeah this is definitely batman approved. It's always good to collect possible goodies. If spider-man ever did that he could have hacked the goblins glider. Very batman indeed.
The movie with the fantastic car was Chitty Chitty Bang Bang. The screenplay was written by Roald Dahl (acclaimed children's author) based on a story by Ian Fleming (of James Bond fame). Kind of apropos that the film crew for that movie had just finished shooting a James Bond film (On Her Majesty's Secret Service).
