Digimon Xros Wars: Toki wo Kakeru Shounen Hunter-tachi

This season of Digimon has a lot of similarity with Youkai Watch: - The main protagonist is a boy who has a device that allow him to see Digimon/Youkai. - During the episode both of them have to face some problems caused by those Digimon/Youkai and they have to solve it. - Also, they both can capture a Digimon/Yokai and use it to fight their enemies.  

both show has the same number of hero and rival, 3 vs 3 Taiki was a legend before the first episode of this show, so does Kazanari Tsubasa Yuu and Yukine were previously an antagonist that had brainwashed by the main villain, and in their sequel, they both took the same role as a supporting character Tagiru (so does Gumdramon) and Hibiki are so stubborn and both have so much guts for being a main protagonist 

-The main characters in both animes have the same personality -The main characters in both animes have the same voice actor -Kakeru's Gyrozetter = Shoutmon x4 -Kakeru have a headset similar with Shoutmon -Chousoku Henkei Gyrozetter have deep Digimon Xros Wars feelings
