Not all anime heroes are created equal. Most of them have inherent powers that they develop over time. But others only gain their magical powers later in their lives. No matter how they receive their abilities, these anime characters had to go through some difficult trials (and traumas in some cases) to finally gain their magical powers.
To borrow a phrase from the Harry Potter franchise, the best anime characters who start out as Muggles but gain magical abilities later are some of the best characters, period. In a lot of cases, they have to work twice as hard to gain their powers, to go through something unspeakable. However, once they are on the other side, they are as powerful (if not more so) than any of the other magic users in their franchise. No matter their origins, these characters have proven themselves excellent magic users.

Eren Yeager Eats His Dad
Stream Attack on Titan on Crunchyroll

Eren Yeager, though he is an Eldian with the inherent power to turn into a Titan, is just a normal boy at first. Despite his ancestral ability, the only remarkable thing about him is his propensity for rage and violence. Sadly, he doesn’t remain a normal child for long when his father activates Eren’s Titan form. Eren then eats his father to gain the Attack Titan and Founding Titan’s powers.
As the Attack Titan, Eren can (eventually) transform at will into a raging brawl-centric giant. As the Founding Titan, he can control all other Titans. This eventually becomes a problem — especially once he activates The Rumbling. No one would have known that an angry boy from Shinganshina would grow up to be the most reviled character in Attack on Titan.
