I found this website that shows some cliches and I'm going to post the ones that I agree with the most. (Although it has "Anime" in the title, manga is the source material for most anime, so technically all these count.)
http://uncyclopedia.org/wiki/Laws_of_Anime_PhysicsBut I'm surprised no one has mention these yet...
1) No matter how much damage a character's body takes, after they recover you won't see any scars. And the only time they get a scar, it becomes a plot device for later on (i.e. The whole throbbing pain from the scar when the person who caused it is near)
2) The more retarded a plan is that the protagonist makes up, the more likely it is to work. In cooperation with this, the antagonist always has a genius plan that fails.
3) Getting stabbed multiple times only kills you if you are unimportant to the story.
4) If the main character has something everyone else has (Devil Fruit, O-Parts, etc.), then the main character's thing will be more powerful or have more uses than anyone else's.
5) If the story isn't about samurais or ninjas, then both of them will make at least one appearance in some form in the story.
6) Whenever a character (Good or Evil) starts to transform, the other side won't attack them in the middle of their transformation, but instead just stand there and watch while being shocked.
7) Protagonists and Antagonists can wield huge ass weapons that would be heavy with having any muscle mass whatsoever.
8) The larger and tougher-looking someone is, the weaker they are, and vice-versa.
9) Transformations, whether mech or monster, are a long and arduous process the first time it occurs. However, the process is sped up and even instant every time afterwards.
10) Armies do fucking nothing. Either they don't exist, or their most powerful forces don't have any effect on the enemy.
11) The "Invisible Sheath" (definition: A sword can be attached to a person's side or back without a belt or a sheath to hold it in) is present in all scenarios. If the protagonist has a sheath, that just means his sword is too small.
12) In the event of a card game, the protagonist alone can spawn from nowhere cards that would be completely useless in any other situation, but are exactly what he needs at that moment.
13) The later a character is introduced, the more badass they are likely to be.
14) When the time comes that the protagonist does something complicated or amazing their first time, he will beat all known records and one-up any veterans.
15) When assigned a task, the protagonist seems doomed to failure and death. However, the more time it takes the protagonist to complete this task the more likely he will complete it.
16) The strength and clarity of a sound do not weaken with distance or interference. One who is fighting in the air will still be able to hear the regular volume comments of his/her companions as if they were right next to each other in a calm setting. However, concentration on menial tasks, like eating or being on a date with some woman, has the opposite effect. Hearing and listening skills will be impaired tenfold.
17) When a character gains the possession of a giant robot, they immediately know how to control it without a sliver of prior training.

Just because someone's head was chopped off doesn't mean they're dead. That's just silly.
