Title says it all, I hear this is something we want to avoid, a character that is too powerful and takes the fun away from everything. I have 2 characters that are essentially god tier and in theory could do anything they want but with mental limitations. These 2 characters need each other to essentially become godlike however in the story and even at the end this never happens. The first character basically possesses and infinite pool of power however never learns about this and always assumed she just has good luck. In spite of how much blessings she got, she is unaware and uses this powers to learn music and play in a girl band never ever training these powers or realizing what she's capable off. She is the reincarnation of a god. The second character is the opposite, a witch who knows all the spells and powers but does not have the pool of power needed to cast these insanely physics defying spells. And is seeking to kill the first character to become whole again but dies before that happens. These 2 characters are an important side arc as the main character protects the first character from the second character. The 2 characters serve a purpose to tell readers of how magic works in this universe and why no human could reach that level of power. Which is described by the second character and is demonstrated frequently by the first character. So yups there we have it, would it make these 2 characters inherently unfavourable to work with considering how strong either could have became but never did? I have no intention of pushing magic that far up the scale but i feel this sub arc is needed to explain it and why magic is kept to a moderate and never more.
