Titans come in all shapes and sizes, with an average height of somewhere in the world 5-15 meters.
For the most part, they were emotionless monsters, and indeed, there was a childlike innocence in their demeanor. When not sluggish, they move in an irregular manner, often with a friendly smile on their face. Once they had caught their prey, they continued without hatred, biting them in half and feasting merrily.
They have no reproductive organs or even a digestive tract, and although they can be temporarily paralyzed if their Achilles tendon is severed, the only way to destroy it is to target their nape.
If you miss this small area, the Titan's body will eventually regenerate and will continue its journey. Your choice is to be accurate or die, but achieving the former is easier said than done.
Worse still, some Titans display unusual malice and are considered extremely dangerous. The Colossal Titan is the most famous, and true to its name, it stands tall above all else. The destructive power of this foe is unlike anything seen before, and many wonder if it has any weaknesses at all. Maybe… ticklish?
Addendum: The Colossal Titan is not amused. Please don't approach him with a feather.
