Kyle

Trivia
He-man theory

While not yet confirmed, fans have highly speculated that Kyle could very well be in fact prince Adam from Eternia, as he resembles his appearance and shy attitude (Even though the original prince just acted like a coward to cover up his secret identity as He-man). Also, his hair and height is almost as identical as Adora’s, which are the same characteristics the prince differed from his sister in the first series.

Although the show runner confirmed not knowing how to introduce He-man just yet, they still hold the TV rights to such character, but not for toys sales or production.

Moreover, “Eternia” and “Grayskull” are already confirmed to exist.
