Battle[]
| << Previous boss | — | Sonic the Hedgehog 3 Egg Gravitron |
— | Next boss >> |
The Egg Gravitron is the boss of Carnival Night Zone Act 2 in Sonic the Hedgehog 3 and Sonic 3 & Knuckles, and the eighth boss overall. While in Sonic the Hedgehog 3 it is fought by Sonic and/or Tails, in Sonic the Hedgehog 3 & Knuckles, it can also be fought by Knuckles if he takes the same route Sonic/Tails normally go through in the Act. In Sonic Origins Plus, it can also be fought with Amy.
Boss guide[]
When the player enters the open arena, Dr. Robotnik appears from the right side of the arena in his Egg Gravitron and starts following the playable character from above. After some time, Dr. Robotnik will drop a large dark green globe on the ground and start hovering directly above it. He will then activate four generators on the side of the Egg Gravitron which will start rotating around it, creating a pillar of electricity that arcs downwards around the globe. This will turn it into an electromagnet for about seven seconds and will draw the player toward it, unless they are constantly moving away. Robotnik then descends to pick the globe up to repeat the pattern, which is the player's best chance to attack the Egg Gravitron. However, the dark green globe will damage the player if they touch it, as will the generators while they retract after hitting the Egg Gravitron.
The Egg Gravitron has a tendency to take a long time to defeat due to the limited chances to attack it relative to the duration of its attack pattern. Getting a Time Over can be the biggest problem when confronting this boss. There are several chances to land more hits on the Egg Gravitron unharmed by using Sonic's Insta-Shield at the right time or having a Lightning Shield. Tails can also damage the mobile from below while in flight.
After eight hits, the Egg Gravitron will be destroyed. The player will then be able to open the Capsule and complete the Zone.
Trivia[]
EggRobo piloting the Egg Gravitron.
- In Sonic 3 & Knuckles, Knuckles usually skips this boss battle completely by taking the lower pathway, which only he can access at the start of Act 2. At the end of the Act, Knuckles ends up in the same room where he would send Sonic and/or Tails flying to the boss arena in their stories. Inside this room there is a Capsule and a teleporter that will transport the player to IceCap Zone after finishing the Act.
- If the player takes Sonic and Tails' path via an upwards facing propulsion tube near the beginning of the Act, the Capsule won't appear, and Knuckles will need to climb up the tube to fight the boss. An EggRobo will be seen controlling the Egg Gravitron.
- Beating the boss as Knuckles will cause cutscene mishaps, with Knuckles still being fired from the cannon at the end of Carnival Night Zone Act 2 to transition into IceCap Zone Act 1 but the latter act will still commence as if he used the teleporter that he uses at the end of Knuckles' usual route in the former Act. In the Sonic Origins remaster, Knuckles will reach an invisible teleporter instead and teleport to IceCap Zone.
- If the player takes Sonic and Tails' path via an upwards facing propulsion tube near the beginning of the Act, the Capsule won't appear, and Knuckles will need to climb up the tube to fight the boss. An EggRobo will be seen controlling the Egg Gravitron.
- The boss's name appears to be derived from the Gravitron amusement park ride, as well as how it uses a gravitational pull on its ball.
