You could have left me here, sealed inside the pod - Rouge finding the pod and accidentally releasing Shadow from suspended animation or Eggman freeing him from suspended animation in Sonic Adventure 2
You tried to take me down - stop the show - Omega trying to destroy Shadow when Rouge accidentally released him and stops the fight.
Seems you've never tasted fear - or loss of control - Omega not knowing about Shadow being the Ultimate Life Form and his powers or Omega being an inorganic member, as robots are stereotypically emotionless.
We all danced in fire - Omega was trying to shoot Shadow or each member of the team has been in a life threatening situation (Rouge locked in a safe as Prison Island was about to explode; Shadow falling from space back to earth; Omega being shut down by Dr. Eggman before the events of the game)
Trapped in this machine - Falling into the trap of working for Eggman OR Shadow being trapped in the pod.
The power that is me - Shadow being the Ultimate Lifeform and nothing could stand in his way.
