Rumbles Idea-The Gauntlet

I think we should set up an official gauntlet challenge for characters. It would be based off of powers, and feature the character(or characters if we did a team gauntlet) going through a set series of opponents. Like, level one would be a small number of training bots with the physical prowess of your average human, level 2 is some pack of animal, and so on until the final hardest level.

Ideas?
