Let's discuss underused characters

I'm just fucking tired of Haruhi Doujins that include Kyon. Why don't we have more Haruhi&Mikuru Doujins? or Yuki&Ryoko? Same goes for Evangelion. Shinji, Shinji and more Shinji. or Kaji. Also, Tsukihime Doujins are way too obvious. Always include Shiki, character I hate, like Kyon. And also, does someone have Excel Saga Doujins? or maybe the Excel Saga Prototype(Daitenjin)?

mmm, I'd say I-no from guilty gear. she's defiantly the seductive character for the gg games, yet she's rarely in any of the GG doujins, hell, that guy bridget gets more action than i-no. :o (baiken's another one, but not as bad)

also, I wouldn't mind seeing some of the ladies from certain rpgs like grandia or wild arms.
