Searched around, didn't find this as a topic. I thought it would be interesting to see what franchises aside from Pokemon people on here support. Also, which ones are commonly mentioned.
I'll go first, since three come to mind.
The movies, TV series, comics, etc. I've been a huge Batman fan for a long time. Overall, it may be the only franchise I know far better than Pokemon.
2) Kingdom Hearts
These games are incredible. Played them since the first one came out, and haven't gotten tired of them since.
3) Avatar TLA
First anime I ever saw as a kid (aside from some DBZ here and there). Recently re-watched them. Still love the series and franchise.
