In "The Marksman", Dino Boy teaches Ugg (Mike Road) how to use a bow & arrow, which comes in awfully handy when a pair of pterodactyls end up fighting over the kid.
Dino Boy makes his DC Comics debut in Future Quest issue 4, on sale now, which explains, at least in this narrative, how he lost his parents. Oh, by the way, Dino Boy's real name in the book is Todd Messick. His parents are named after Dale (creator of Brenda Starr) & Don (voice of Bronty, Scooby-Doo, Astro, etc.) Messick. The Impossibles will appear in issue 5, and Frankenstein, Jr. debuts in the back-up feature in issue 4. I am guessing they're planning to use virtually all of H-B's adventure heroes of the 60's in the book.
"The Marksman" merits an A.
