I apologize for the lack of content lately. I've been working on the book, and on the new comic I'll be releasing very soon! Keep an eye out, and I really hope you enjoy it! It will be replacing the one-off story-centric pieces for the most part as I feel a comic book medium suits the presentation of the story better. Anywho, here are the rival Buckball Champions.
The show alluded to the fact that Buckball has grown into a national sensation. I like to think it's grown into something on the level of American football, which is the obvious analogy in the show. I think there is a lot of financial investment in the sport, and as such, even high school/college level Buckball teams are highly sophisticated. As Twilight's School is not really all that sport-oriented, their school does not receive as much funding as others, which means Halien has to pull his weight a bit as Buckball captain.
