Living Anomaly

I will create a hypothetical scenario where an anomaly confronts an entire cosmology (from the weakest to the strongest being and entities) I will describe it:

Description:

The Anomaly is an enigmatic being that breaks the laws of reality as if they did not exist, being a fundamental error in reality, something that should never exist, breaking fundamental laws of reality and performing impossible feats.

Abilities:

Logic Infringement - Can infringe the laws of logic as if they didn't exist, perfoming logically impossible feats with ease, affecting reality in chaotic and potentially irreversible ways. For example, becomes existing and non-existent simultaneously or land actions and movements before they perform them, infringing all the laws of physics and causality at any time, place or different dimensions.

Undetermined Existence - Exists in an ontologically indeterminate state, not being alive, dead, undead, sentient or inanimate but existing in an undefined gray area within and outside the classifications/categories of existing beings, immune to all forms of life and death manipulation.

Note:

Choose the cosmology of any verse you know well and say how far the anomaly would go with their abilities and nature.

Paradox Entities are living anomolies whose very nature is a Paradox. By all accounts of functionality and rationality, they should not exist, and yet they do.

What would you perceive as a being or creature that is an existing impossibility that contradicts itself? Give your examples of living paradoxes down the below in the comments

In many anime, especially isekais, the main character possesses some kind of 'cheat power', which allows them to defy, circumvent, or simply take advantage of the rules of power in the world they are in. The nature of this 'cheat power' varies between series and characters, but commonly allows them to amass immense power and grants them an insurmountable advantage.

So, the question: if you were taken, through any means, to another world, what would be your ideal cheat power?

A few notes: No absolute powers right off the bat. If you really want an absolute power, talk about how your initial cheat power might develop over time to reach that level. Your power shouldn't really let you perform feats such as rewriting all of reality the moment you get it, though it could very well develop to that point.

Also, this is not limited to powers listed on the wiki. If you want to describe a custom power, go right ahead, just keep the prior limitations in mind.
