Many of the side characters in Captain Tsubasa could’ve been very generic stereotypes but I really do believe almost every single one of the main rivals that Tsubasa encouters are not only very interesting but interesting enough to be main characters in their own series. Truthfully I prefer almost every one of those rival characters to Tsubasa who I find to be really boring (but I guess that is usually the case with most protagonists of shonen series.
In any case, I have said it before and I will say it again. The best character is Hyuga Kojiro who very easily could have been that cool bad character that one loves to hate but is usually very one dimensional for most of the series until they decide to flesh them out. But instead they decided to show just how much of a hard worker Kojiro is and how selfless he is as well right from the start. Aside from his rather combative and harsh personality in the field, he is a person that one could look up to and admire. His life is not easy, as he has to support his family who is struggling financially by both working and taking care of his siblings. He not only does it but he understands the situation and doesn’t hold a grudge against anyone for his predicament. And finally, despite all that going on, he decides to continue doing what he loves and works towards his dream of being a soccer player. He truly is the antithesis of Tsubasa who was born a genius soccer player with a whole family who not only loves him, and has financial security but they also do everything they can to allow Tsubasa to pursue his dream of becoming a pro soccer player. One has everything given to him and the other has to struggle to achieve his goals.
Hasta la proxima,
