Well, I've been reading Peerless Martial God (also known as God of Martial Arts) this week and I might have finally found my ideal and if not the best MC (main character) ever, Lin Feng.
A little background about what 'Peerless Martial God' is all about: Basically it's a world where the strong bullies the weak and people's statuses are decided by the levels of their cultivation of martial arts. It matters not if one is related by blood or not.
The story revolves around Lin Feng, a reincarnated soul of the modern world whose consciousness merged with the cultivator Lin Feng (same name) of the martial arts world. The cultivator Lin Feng is very weak and is considered a "trash" cultivator thus being bullied in this world. It's a story about his vengeance and revenge to anyone who has harmed and will harm him.
As to the reason why he is my ideal MC, let this scene speak for itself:
This might seem heartless of me but I've always hated it when an MC gives his enemies a second chance. Most often than not, most spared enemies after escaping the brink of death will just come back and will try to come back the MC again. However as you can see on the scene above, Lin Feng is different as he will spare no one who dare harm or plot something against him.
I also love the fact that when one of his enemy called for a powerful backup, he didn't face the back-up head-on and instead tried to find a way to kill the one who requested for back-up first before escaping.
Much more how he makes sure to return the favour. If someone wants to kill him, then he will try to kill them too. If someone wants to cripple him, then he will cripple them first. And if someone wants to cut off his arm, then he in return will also cut off their arms. XD
Again, he always make sure to return the favour. Apologies doesn't work nor is begging or bribing him. XD
