Shadow will still have the spindash and homing attack like Sonic but with some differences. The spindash will have a bigger damage cap but it will have a faster release time so getting to those bigger numbers will be difficult. At the start of the homing attack, Shadow will leap into the air and start floating up and down. You have to aim him at the enemy and press Z to have him charge forward. He'll miss if timed incorrectly. His last attack will be the chaos spear, which will work similarly to DK's coconut gun, where he charges up and with a correctly timed Z press will deal a lot of damage.

So about that poll, I'll give you a scenario. Shadow has been injured greatly by Sonic during their battle (you're playing as Sonic by the way), and is about to fall, but then he gets a burst of power flowing in him that gets him back up, and then his idle pose becomes static but intimidating (second image on this post) and he goes all out on Sonic, not holding back. Which song would best fit this scenario?
