Spotlight on Frederick

As to whether he's a superhero, we're not quite certain. The extra chair in our house is always for Frederick. If there's an open seat in the car, Frederick is usually in it. If it's lost, Frederick took it. When there's no one to talking, Frederick seems to have something to say. Dynagirl is convinced he's a big hairy dog; Dash has joined that bandwagon. Cosmic Boy has a theory of his own. Mr. Incredible, one who has a long history of hearing voices and having friends that no one seems to see,
thinks he looks like Waldo, from the "Where's Waldo" fame. Wonder Woman doesn't even join in the discussion, I guess she's used to invisible things with her jet and all. Honestly, I don't know what the mystery is, I can see him quite plainly in the picture above, can't you?
