This was a small format graphic novel featuring two stories, "The Mask of El Toro Fuerte" by Capizzi, and "Enter...The Viper" by Slack. The artist in both cases was Tomás Montalvo-Lagos. The artwork wasn't bad, but the stories were really not particularly inventive or interesting, and worse, featured clichéd villains and uninteresting story lines. Why they're Jackie Chan adventures I have no idea because there's no kung-fu involved at all, not even vicariously. They were more like Indiana Jones adventures, but I guess Harrison Ford wasn't interested - either that or they couldn't afford to pay for the use of his name?
I dunno. The adventures were not the great. The first was about a magical lucha libre mask which gave extra strength to the wearer, and the other about some female thief which seems to have borrowed from a Doctor Who episode if I recall, but I really am trying not to! Admittedly these were written for a much younger audience than me, but even so they were pretty limp and despite being a fan of Jackie Chan, I can't commend this as a worthy read.
