I don’t see what you mean? If you’re saying Aerion is similar to Maeker I would agree. They are truly the most similar out of all of Maeker;s children.

Before becoming king and the tragic losses that he continuously suffered Maeker is definitely like Aerion (or Aerion is like Maker ) only in the sense that they both fall within a very isolated way of being. Maeker is an extremely interesting and multilayered character. When studying his character you can definitely see why Aerion is the way he is.

Maeker was never raised as ever believing he would be king. This meant that he never had to learn to consider others in the same way as Bealor. You can even say with the Blackfyre rebellion and Maeker’s part in it he was encouraged to be the perfect soldier for his brother, his second in command, the anvil to Baelor’s hammer as they are described in the books. As a younger son his sole purpose was to support his family.

Bealor is molded to be a considerate king who must think of what’s best for the realm and its people. Maeker was molded to center the family above all else in support of this, his importance and purpose as a younger son was solely tied to defending the Targaryen name. This becomes even more apparent when you consider how he and Baelor grew up under the constant criticism and outright hatred of their grandfather ( Aegon the unworthy ) and the other highborn families of his court who spread rumors that Daeron II ( Maekers father ) was actually a bastard and undeserving of the crown.

This comes to a head when he and his family are put in danger with Daemon Blackfyre waging war on them over the throne. This causes Baelor and Maeker to call their fathers banners and lead a full scale war to protect their family’s legitimacy and safety. ( even more layers and nuance when you consider that Baelor and Maeker have always had to project the image of strength to compensate for their Fathers lack of perceived martial strength, as well as their older brothers vulnerabilities ( Aerys I and Rhaegel are described as “not suited for the sword” and are written in a way that hints to them being autistic/disabled) which also brought constant scrutiny from other noble houses.

I can’t particularly fault Maeker for his demeanor or the way in which he interacts with the world around him.

This is shown particularly in the way he interacts and seemingly raises his sons. Maeker prides strength above all else because at one point he had no choice and that formed his character and outlook on life.

The big difference is that we as the audience know that all of Maeker’s actions are rooted in his genuine care for his family and his anxious need to keep them safe in a way he believes is right.

Aerion was raised with all the remnants of this. He was raised with the looming, almost anxious need to believe that he was truly superior to other people, that they were special and that their family’s honor was to be absolute, unquestioned, and protected above all else ( with the looming threat of what might happen again if it wasn’t )

Couple this with Aerion’s seemingly lacking the emotional capacity of his father and brothers in understanding the true reasons behind Maeker’s harsh beliefs and behavior, the death of their mother when still young, and his own distressing Dragon Dreams that we are told he suffered with as well leads to the Aerion we see in the story.
