Chara doesn't fight because he knows he's too valuable to his team to be gone for 5 minutes; which is the same reason he usually bails on a fight if he feels he's in trouble. It has nothing to do with him being a coward or anything like that.
I didn't read all of the posts here, but there are 2 different Charas. One is where he is just going through the motions in a fight and one where you piss him off and he turns WARRIOR MODE on. You can distinguish WARRIOR MODE from his other modes because if you watch the replay you will see something distinctive done by his opponent that induces a SUDDEN CHANGE in Chara's facial expression. Then, the dead giveaway that he is in WARRIOR MODE is that he will start swinging with BOTH HANDS. At this point, he basically doesn't give a **** what kind of destruction he causes and everyone just needs to get out of the way because he will have no sympathy or care in this mode. Chara HAS NEVER LOST A FIGHT in this mode. However, he's had a couple draws or slight losses when he's just going through the motion. WARRIOR MODE is one of the coolest, most exciting things in hockey to watch and it's a treat to see it from Chara as long as no one gets seriously injured... Then it's just unfortunate.
Warrior mode??? HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA....dumbest thing I've heard in a long time!!
Chara can't fight...PERIOD!!! He DOES fight once in a while...and if he grabs a non-fighter who is around 6 feet tall and 200 lbs...Chara usually wins. If someone 6'4 220lbs or bigger grabs onto Chara, he throws a few punches and then usually drags the other person to the ice, ending the fight, but that definitely doesn't mean he won the fight.
