Alicorns are supposed to be powerful thought. You can’t have someone be an alicorn and make them a waitress. They need to be incredibly powerful because the onlyt four we have seen can shape the earth itself.

They are supposed to be powerful. But that is just more of a reason to not make alicorn OCs

I want to ask you one question…

How powerful do you think Twilight Sparkle was when she ascended?

Powerful enough to walk straight into the land of the dead, stop three beings of evil, force cutiemarks onto somepony else, complete a spell that has eluded unicorns for ages and enter void made entirely of magic.

Also, afterwards, she was able to save the universe from a thousand years of twilight and chaos, save a different universe from a thousand years of darkness and enslavement, defeat a being capable of eating magic and survive absorbing the power of three alicorns who are individually near OP.

If the point you were trying to make was that Twi was a normal pony before ascending to being an alicorn and was still normal while an alicorn, you seem to have forgotten these things.

She was not a normal unicorn. She was the personification of magic.

But have her powers increased since then?

She’s been learning new spells and getting used to flying. I don’t really think that’s solid proof of her being more powerful, smarter maybe… but not more powerful.

Hey, buddy, you cannot ask for me to prove my point and completely disregard it when I do. Yes, she HAS gotten more powerful throughout the series. In season one she would be tired after teleporting multiple people and there would be magical burnout afterwards and now she can teleport the whole cast across the everfree. In too many pinkies, she could barely turn an apple into an orange and now she can turn whole ponies into a different species. Her magical abilities HAVE gotten stronger canonically.

True, but is she on par with Princess Celestia?
