The Ackermans are Ymir's subjects. They are, however, immune to the Founding Titan's ability to alter Subjects Ymir's memories. If I were to draw an accurate conclusion, it would be based on the assertion in the Manga. Assume the Ackermans are unable to resist the fundamental Titan control. In that case, Ymir is unlikely to be able to create Titan body parts for them. As a result, according to my logic, Ackermans cannot transform into Huge Titan. Rod absorbed liquid from the titanic Titan and grew enormous. Regular titans are humans who have been injected with normal titan fluid, causing them to be of average size. In essence, by injecting titan fluid, you gain specific abilities. Rod was more significant than the colossal Titan because it was an unusual one, implying that he had a plan to reclaim the Titan that was founded. He was massive in order to achieve his goal because he was motivated by his dream.
The Colossal Titan may be 60 meters tall, but there are a couple of Titans who are taller. Other anime have terrifying gigantic threats as well. The Colossal Titan is one of the universe's tallest beings in Attack On Titan. It was Marley's most lethal weapon until Bertholdt's defeat at the end of the third season, standing at a staggering 60 meters.
Rod, the colossal titan, was still unable to stand after his transformation because his back injury had not healed. However, the heinous creature would not give up his final desire to destroy, so he crawled toward the nearest settlement, his face scraping across the ground. During his unstoppable crawl to the wall, Rod's face was obscured. However, this massive titan did manage to rise at one point, allowing the world to see his damaged face. During this memorable moment, many viewers turned away from the screen. Rod's shattered Titan face was simply too much for him to bear.
There are no exact measurements of how tall the wall Titans are, but it is implied that they are between fifty and sixty meters tall. Given that they came from the fifty-meter-tall walls that protected Paradis, there is some evidence to suggest the former. They are also strongly reminiscent of Colossal Titans (which stand sixty meters tall) and may have been built horizontally rather than vertically into the walls. The Titans of the Wall are best known for their role in the Rumbling.
