Who is the strongest character in Dynasty warriors 4 apart from lu-bu? I have had many opinions to this question but im looking for yours:) any thoughts to this topic i would much appreciate

That depends on your preferences and who you are good with. Thats the bueaty of the game you can literally take any of the characters and beat anybody if you know how to use them right. For example I have used Cao Cao since DW 2 and I have taken on hard or chaos mode on all the games since and I have yet to be defeated. Now in many faqs you will find that he is usually rated pretty mediocre. But the way his fighting style is suits me perfectly. He has a very anguliar attack structure which can make him extremely precise or extremely vulnerable. By equiping the right items and playing the angles just right he can be nearly untouchable. Also he holds one of the best horse attacks. Red hair + Cao Cao = your enemie's untimely death. I mean its pretty sad when you can clear Wu Zhang on hard without getting knocked off the horse even once. But the point I am trying to make is this there is no best character, its all in how use a character's strengths and weaknesses. What I would recommend is to pick a character that you like and that suits your particular fighting style and use him or her the most. Get know each of their moves, their strengths and weaknesses and find ways that best utilize these.

Thanks, i'll keep that in mind. I kinda have always like liu bei thats the character i have used to beat the game in 3,4 and 5! Anway thank-you very much for your advice!

Lu bu is the strongest. None else.
