Which heroes move the fastest along the ground?

When one plays the heroes vs villains games, eventually every player gets selected to be the target for your team. Often times the best strategy to stay alive when selected is to runaway. Sure, sometimes working together with your allies is a superior strategy, but other times the team can be scattered through-out the level and the enemy team has joined up.
In that case it makes a lot of sense to just run for it and try to meet up with some allies and help them ambush the pursuers, or just keep running. The longer you stay alive the more chances your allies will have to attack the enemy target.

With that said I was wondering which heroes move the fastest?

Certainly Boba Fett, the only hero with a jet pack, can move the fastest vertically. Though sometimes flying just makes you a more visible target. But I mean along the ground if your just trying to escape. Also if you know which ones move the slowest that would be nice.
