Sureee, I’d love to help and brainstorm with you loll. Well, I love a great fatalistic view on life, and believing that some things, if not everything, are predetermined, so maybe the character can have a fatalistic POV on life… which, as you said/stated, causes them to subconsciously limit their abilities as they believe certain events are meant and destined to happen and take place, and thus, they avoid interfering even though their power can possibly change it all. And I feel like this would bring a great theme of ‘Choice VS. Fate’. Additionally, I feel like overtime, you could have the character have a little ‘self-discovery journey’ and try to understand and comprehend their power to the fullest extent. OOH! Another thing! Because this character can literally do anything, you should have them question themselves. By this I mean, because they’re now educated on the fact that they can do pretty much do anything make them have significant moral dilemmas. Have them ask themselves “should I do this, just because I can?” “What if I alter this, and I somehow, someway bring a much more powerful force or person or entity can do better than me into this world?” This allows the character to grow as someone who thinks before they do things, and try to consider every possibility, and not be impulsive. Maybe the character can also use their Metapotence to set up challenges or tests for others, determining their true character, strength, or wisdom. And lastly, maybe they can have an Identity Crisis. When literally realizing all they can do, they ask questions such as “What does it mean to be human when I can do anything?” or “Am I still the same person I was before?” I feel as if this can lead to emotional conflict if not introspection.
