you have the ability to merge objects with random fictional characters once merged the object will become alive and take on the appearance of said character though they will also somewhat resemble the object if the object was a doll/action figure then they will simply gain the physical features(and gender features if they were a different gender than that character) while keeping their own they will have the the memories personality and powers of said character but if the object had an intended use and property then the the merged result will have a version of that character’s personality and identity oriented a bit more around that use and gain a power based on that property like say merge your oven with Gloria hippo and that your oven is now a robotic version of Gloria hippo with a love for cooking and the power to generate heat along with cooking intuition who believes that it is your personal chef or Nick Wilde with a rock and you’ve created living sculpture of Nick Wilde with stone mimicry ( if the item is owned they will believe they are free working employees of the owner) also if you have merged an object with fictional character that had a relationship with a character you had previously merged with an object then their memories will change to include their relationship anyone has this power cannot have it removed even by omnipotent force and the creations of users even godlike ones cant effect others users directly but can still harm other creations
Your world is has been besieged by villainous people who also have this power and you have decided to use your power to stop this threat
Get 4 or 5 Random Character and then combine them with objects you own and tell what powers the merged result would have based on the character and object what appearance they would have and how you would train them to become heroes
