(No limit for the level of both, you can create/mimic the powers at any level)
Meta Character Creation: The ability to create any fictional character, with any traits and abilities of any level. You can design it to be under your control (the new being will be your servant, assistant, advisers, guardians or power-sources, or emerge into existence to carry out more tangible tasks.) Or make it free if you didn't write (under my control) command when you created it.
Fictional Mimicry: The ability to copy and combine any power, technique, skill and trait (of any level) of any fictional characters.
So do you want to mimic the power of fictional character or create the fictional character with his power as your loyal servant?
