They Came from the Gateway: Part 2 is the fourteenth and final episode of the second season of the animated series, Martin Mystery. It was originally released on October 27, 2004 and it was also the continuation of the first part of the episode.


It's the final episode of the season and things are looking pretty final as monsters appear all over the world and overwhelm all the Center agents while the now evil M.O.M. and the Gatekeeper unite to destroy Martin, Diana, Java and Billy. Is this the end of the line for the gang and the Center?
