In the game, You get access to Unlimited Mars, which is where you fight powered up versions of the normal characters at a high degree of difficulty. The first time I tried this mode I was taken down in 2 rounds, in less than twenty seconds without landing a single hit on my opponent. My first opponent. So if u are looking for a challenge, you've got one in Unlimited Mars.
