Guys you could take with prep
The recent "who could you take" thread got me thinking. Here are the rules...
1. You have an unlimited amount of money to hire, build, buy, etc. anything that exists on our Earth (i.e. no mutant nullifiers and such). Also unlimited time for prep.
2. You can pick the field of battle, and even though others can help you with prep, you must fight him/her alone. The comic character gets their regular equipment but no prep.
3. Let's leave BS comic appearences out of this thread. Yes it's amusing, but no it isn't practical.
...I'm thinking with a good plan, most street level people would go down. But I'm curious to see if anyone thinks they can take more powerful people. Post your plan, not just "I could beat Iron Man"...we need reasons.
