1) Monkeys rule! (well, Apes and Monkeys) I love my monkeys. ahem... not in that way.
2) V'han is easily fixed by something I don't see Champions books address: Bring in the cosmically powerful entity who requires the heroes to alert it/them to the presence of the threat so they can spank V'han. Dr. Strange did this all the time; you know, Eternity, Living Tribunal, Eon, etc.
3) Takofanes not gonna get fixed by me. He's just too much work. I'll drop him because I can do without a weak version of Kulaan Gath.
4) Frankly, powerful mystical villains seems to be a weak spot for Champions. They come off pretty plain jane, vanilla - nowhere near as stylish as Baron Mordo and Dormammu.
