You can be on team Sonic or on Shadow's side

Sonic, Tails and Knuckles (if youre on team Sonic then you as well) jumped out of a G.U.N helicopter as they landed down to Tokyo, the three of them standing up in some stances. Sonic was in the middle and front while Tails and Knuckles were at his sides slightly behind him.

Shadow arose from the flames as his shoes tapped along the mtal texture of the ledge that was tilted up. He could be seen more clearly with the fire next to him and behind. He narrowed his gaze as he has a stoic expression with a slight frown.

Shadow: "Well you're a colourful bunch." He said in slight disdain and mockery but said it in a subtle way, gazing down at them, arms crossed.

Sonic: "Look, we're not here to fight you-" he says as he steps forwards in a reassuring way before knuckles interrupted.

Knuckles: "Actually Sonic, I would very much like to fight him." He whispers quite loudly to Sonic with a confident smirk. Then he proceeds to launch himself at Shadow with his knuckle/glove in front. Time seems to slow down as Shadow blitzes forward in a flash and grips his knuckle, then twisting it with ease as Knuckles yelpt in slight pain. Time returned back to normal as he teleported behind Sonic and Tails, drop kicking Tails first and then grabbing Sonic by his furry neck and using his air shoes to boost himself up into the sky, then slamming Sonic to the ground from a high advantage, creating a big amount of dust and energy particles.
