Jet Mobile

To start the battle with Jet Mobile (ジェットモービル) at the end of Mushroom Hill Zone Act 2, jump on the satellite dish to destroy it. This will reveal Robotnik's machine in the process. If you can hit him a few times before he moves offscreen, the Boss Battle will be easier to win. When Robotnik flies off to the right, chase after him and follow him through an obstacle course. When you are running through the obstacle course, jump to avoid the spikes (when playing as Knuckles, there is an additional spike pattern that requires the player to glide through it.) If you keep running, you'll catch up with Robotnik. When he switches off the boosters, you can hit him. If you have a Flame Shield, the boosters won't hurt you, so you can attack Robotnik repeatedly. If you're fast enough, you can hit Robotnik from directly underneath the machine, regardless of whether or not the boosters are on.

After eight hits, Robotnik's machine starts to explode, but Robotnik still isn't worried. However, his machine soon crashes into a tree and it falls apart. When you've opened the Prison Egg, Sonic will look up and you'll see the Flying Battery Blimp fly past. Robotnik flies up in his Eggpod and enters the battleship. Sonic immediately jumps up and grabs onto it.

Trivia

• When playing as Knuckles, with only one life left, there is Robotnik instead of Eggrobo on the Jet Mobile.
