Last I checked, sappers don't just dig, after they dig they place explosives and blow stuff up. Lack of Boom! aside I give this entry 10 stars because The Title of the story on page 20 makes me laugh like an 8 year old. "The Sapper's Funk Hole." bwahahahaha! Oh my what a difference 80+ years make.
I really dig the art on page 36.
So on page 43 he's apparently at Hogwarts. On page 49 they got it all wrong, Quicksilver is a mutant , not a human! Good fun, enjoyed skimming through that.
