Ben 10 Vol 3 - Side Effects

Teamwork and selflessness are key if Ben, Gwen and Grandpa Max are to keep the Earth and the Omnitrix safe. When one of Hexlord’s mystic charms is found by Gwen, she must decide between her new-found lucky powers or defeating the sorcerer (Lucky Girl). 

Things go a bit haywire as Ben is stuck as Grey Matter and is kidnapped by a sci-fi geek (“A Small Problem”) and even more haywire when Ben catches a common cold — but the side effects on his alien transformations are anything but common (Side Effects). Finally, Vilgax is back and decides to take his quest for the Omnitrix into his own hands (Secrets)!
