Terebi-kun is the most obvious one - it's a magazine largely centered around revelations regarding certain TV and video game franchises, one of which is Pokemon, and it's also one of the magazines listed in the anime opening theme during the "as published in these magazines" list.
G50, do you know where you encounter said magazine? And about the summary you have a problem with Oshawott and Krokodile. Newtype is famous for misconceptions like that the exhibition match hasn't happened or thagt the last episode is only about Alder and fitting on the side the Dawn's departure. What do you think?
