No, the Eldians need to consume a Titan Shifter in order to become one. If Eren dies without being eaten, then the Titan Shifters die with him.
If a shifter dies not being eaten by a titan then the power goes to a newborn eldian at random.
Those with the power of the Titans could regenerate their bodies, as long as they had the will to live. They were even able to grow back their entire head in the event of a partial or complete decapitation.
Basically, you can kill a titan shifter by causing damage to their spine, ig. I've never seen them get hit in the manga or anime, but that must be how.
Put simply, Titans eat people in the hopes of regaining their humanity, and if they consume the spinal fluid of a Titan Shifter - one of nine people who can transform into Titans at will - they will return to normal.
It gains the other's powers. It was seen in chapter 62 and further explained in the next. Dalmatia wrote: It gains the other's powers.
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.
When he is capable of explaining what's going on while piloting a Titan from the nape of the neck, he says he can't really feel the injuries. Titans heal incredibly quickly, recovering from severed limbs and gouged eyes within minutes.
Pieck's Cart Titan is arguably the weakest of the Nine, but it comes with several advantages.
A Titan Shifter needs to draw blood in order to transform, and some, like Eren, bite into their hands. This can be a painful experience, but Shifters do not need to worry about these injuries because they will heal extremely quickly.
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.
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.
Eren Yeager - Wikipedia
that he first met Grisha about 20 years ago. At this point the attack on Wall Maria which coincided with Grisha's death happened 5 years ago. So Grisha had in fact been inside the Walls for 20-5 = 15 years!
Eren Yeager
The War Hammer Titan is the final Titan to make its presence known in the series, but its impression is still a really strong one. Its mastery of crystallization means that the War Hammer Titan can easily destroy its enemies with the crafty use of its powers.
Unlike other species, Titans did not mate, and their interactions were nonexistent with organisms other than humans; their sole purpose in life was to seek out and devour humans.
The Attack on Titan fandom still can't come to a consensus about the Curse of Ymir, a rule which states that a Titan Shifter can live a mere 13 years after acquiring their Titan powers, and what this means for our protagonist, Eren Jaeger, who possesses more than one Shifter power.
Perhaps the kindest character in the series, Armin Arlert always looks for the good in people. Even after discovering that Annie is the Female Titan, he wants so badly for it to not be true, practically begging her to prove them wrong.
Silkie is physically the weakest character on Teen Titans. He has a relatively peaceful nature, and, though he has some abilities, they pale in comparison to the others on the show.
1 Levi Ackerman
Levi's abilities allow him to excel in fighting not just titans but also human enemies. 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.
Pure Titans are created by injecting Eldians with Titan spinal fluid. If a Pure Titan eats the human body of a person who possesses one of the Nine Titans, said Eldian will revert to human form and gain that Shifter's powers, whereupon they are cursed to live only 13 more years.
They do seem to become less active at night or if deprived of sunlight, and so it may be possible they draw their primary source of energy from the sun.
After Eren is swallowed by a Titan, he finds Hiana's dead body in its stomach and her face mutilated from the stomach acids, making Eren realize the same will happen to him when his hand starts to burn up.
After the Scout Regiment's return to Trost District, Eren sees his father's memories in his dreams and comes to the realization that Dina was the Titan that killed his mother.
When Eren was eaten and swallowed by the Bearded Titan, he found himself in its stomach along with the bodies of its victims. His rage at the Titans caused him to burst out of the Bearded Titan's stomach by transforming himself into the mysterious Titan and going on a rampage against them.
