i only know of one other line.
pokemon chronicles has an episode titled the legend of thunder which was released in japan in 12/30/2001, but was not released in the usa until 07/03/2006 for part one and 07/10/2006 for parts 2 and 3. it features 3 trainers whose names are: jimmy (based off ethan, the male player character from Pokemon gold, silver, crystal, heartgold, and soulsilver), marina (based of kris, the female character from crystal.), and vincent (based off no one) so jimmy, marina and vincent are from new bark town, and attempt to stop team rocket agents attila and hun from capturing raikou. again, thats the only other line I know of. there could be more.
thats all, folks!
