Our contestants are supposed to prepare for an unknown threat or enemy appearing in a week. They need to arrange and assemble plans, tools, gear or whatever might suit the unknown incoming situation. Additionally, the threat would be relative to their power and universe, making it balanced. Assume its a serious threat on the same level for every individual character and verse. Prep is a necessity for anyone to win, meaning stronger characters would lose without it if just showing up to fight.
Its simply a battle of intellect relative to their situation and universe.
Which of the following would be best equipped, end up with the best results or impress the most?
