Ralph is not thrilled at being suddenly expected to fight all sorts of terrifying aliens, especially when he realizes he's up against even bigger bullies than he was on earth. But to save earth, his new friend Joona, and himself, he's going to have to find some courage somewhere and fight back.
Splashy color and wild hijinks abound on every page. There's plenty of cartoon violence, but no real gore, even if there's a lot of serious issues going on. The wacky aliens and Ralph's horror at being forced into a sort of Luchador fighting suit are played for laughs while Joona is sexually harassed and threatened by the evil alien general and admits to having been outcast and abandoned by her people because of her differences. Although Ralph wins out in the end, the story isn't over - he might get pulled back to fight at any time - and he has some pangs of conscience about scaring off his bullies on earth by being a bigger bully.
Overall, however, everything is played for laughs and it's the kind of adventure that Captain Underpants fans are sure to love. As an adult, I find the "average or wimpy boy saves the day" trope to be annoying and overused, but at least Ralph is not white. The humor is mostly pretty childish and while the threats against Joona and earth are definitely mature, they're likely to go right over the heads of the target audience for this, which is definitely below the Pilkey Line.
Verdict: Add where you have lots of fans of Captain Underpants and other gross and silly comics.
