Who is the Titan with no skin? Out of the Nine Titan Shifters, only the Colossal appears to be completely skinless, the Female only partially so.
The Wall Titans are similar in appearance to the Colossal Titan in that both their surfaces are covered primarily in muscle tissue and lack skin (although the Colossal has exposed bone over the muscle tissue of its form).
All Titans have thick skin that requires a special blade to cut through it, but the Female Titan's anatomy has an extra defense. She can select parts of her body to harden into an impenetrable crystal, and while it's established in Season 2 that Eren's titan can also do this, Annie has full control of this ability.
If you're talking about why deos the Collosal titan don't have skin. Then it is probably because of his abilities. His ability is to let off really hot steam capable of burning everything around it.
Although the Attack Titan lacks any unique abilities at its base, this changed in Season 3 due to a special serum possessed by the Reiss family. The serum upgraded the Attack Titan, allowing Eren to harden his skin into a crystalline substance that is invaluable for both defense and offense.
While certainly formidable, the primary disadvantage of the Armored Titan's skin was the decreased speed of the Titan form. Whether due to increased weight or restrained movement, the Armored Titan was only capable of maintaining moderate running speeds when completely armored.
I believe Eren's Titan eyes lost their blue colour as a result of eren's psychological and mental state. As you remember his eyes even when reflected in the sun have no white in them which i think symbolizes the character's hope and dreams, but eren has lost all hope so his eyes lost their white.
This Titan was the first Pure Titan shown to speak words with meaning. The second was Ms. Springer. This Titan was the only common Titan seen that displayed a range of emotions.
Founding Titan is the first and the strongest Titan of all the nine. If the Founding Titan is someone from Royal Bloodline, then it will possess limitless power. Eren Yeager was not someone of royal blood that's why he asked for Zeke's help to use the Founding Titan to its fullest.
He notices too late that Eren's Titan on the ground below is in fact merely its hardened shell, and in the moment of vulnerability, Eren, in his human form, strikes at the Colossal Titan, pulling Bertholdt from the nape as the Colossal Titan collapses in defeat.
This indicates that perhaps the point of this titan was not to be inherently female, but has abilities centered on crystallization. Therefore, if a man were to eat the human wielding this titan, he would possibly retain his masculine features, but his defining characteristic would be to crystallize.
Manga. The Female Titan (女型の巨人 Megata no Kyojin?) was one of the Nine Titans and possessed the ability to easily mimic the attributes of the other Titans. It could also selectively harden parts of its skin and attract Pure Titans with its screams, possibly due to its aforementioned mimicry ability.
These nine Titans are remnants of the founder Ymir Fritz's spirit. Each has their own unique name and power set, passed down through the Eldian line. Eldians who possess the Power of the Titans can revert to their human form and retain abilities such as speech and human emotion while in Titan form.
The creepiest of all the pure titans is the Smiling Titan. Dina Fritz died with a smile on her face and was reborn as a beast that would set the entire plot of AoT in motion.
Pieck's Cart Titan is arguably the weakest of the Nine, but it comes with several advantages. Unlike its eight brethren, the Cart Titan walks on all four legs, making it an excellent method of transport. Pieck often has large structures attached to her back, which carry both people and weapons.
The surrounding Pure Titans, sensing Eren's desire/unknowing command for her death, attack the Smiling Titan. They all tackle it, rip it to shreds, and devour it, whilst Eren and Mikasa escape.
The Female Titan is a titan of above-average height, power, and agility. It also has high-level hardening and the ability to attract pure titans to it. Annie's female titan was powerful enough to soundly defeat Eren's Attack Titan in the first season, and for obvious reasons.

He's also the only non-titan character in the anime to take down a Shifter Titan single-handedly as was shown when he defeated Zeke in Beast Titan form. After that, he can still go on to slaughter dozens of titans even with just a handful of resources available.
The nine Titan powers were the Founding Titan, the Armored Titan, the Attack Titan, the Beast Titan, the Cart Titan, the Colossus Titan, the Female Titan, the Jaw Titan and the War Hammer Titan.
The ones that can talk include Ymir, Zeke, Pieck Finger, and Lara. Speech is not defined by the Nine Titans, as Ymir could talk in her Titan form while Porco Galliard could not, despite them both having the Jaw Titan.
We know that a titan shifter contains enough spinal fluid to distribute their powers to at least 3 people (although this might vary person to person). So if Maria, Rose, and Sina each had 3 people evenly consume their spinal fluid, there would be nine shifters (each holding ~1/9 of Ymir's power).
A Titan, with Eren in its mouth, bites down and severs his left arm and then eats him.
In the official English translation of the manga his last name is spelled Yeager. In the official translation of the anime, it's spelled Jaeger. So, using either one is pretty much fine. Jeager is an actual German name, and since many of the names are german, I think it works better.
While the discussion was going on related to how the Eldians are mistreated, Eren leaves the meeting to meet Zeke and execute his plan. Eren was an infiltrator on the Marley land, and the only reason he chopped his leg and gouged his eye was to mix well with the Eldian soldiers.
