The Egg Salamander (エッグサラマンダー Eggusaramandā?) is the true final boss of Sonic Rush. It is a powerful lizard-like mecha that comes in two versions, created by the combined efforts of Dr. Eggman and Dr. Eggman Nega. It is fought in the extra zone Exception, a dimensional rift caused by the merging of Sonic's world and Blaze's world.
The Egg Salamander comes in two versions, depending on the pilot of the mech. Both versions however, are mostly colored purple with some red, blue, pink, black and green. Living up to its name, the basic Egg Salamander resembles a type of lizard, but without legs.
When Dr. Eggman is the pilot, the Egg Salamander has a rather bulky appearance. In this form, it has a pink cockpit located on the head with a fin blade on the top and large cannons on each arm. It also has a four-segmented tail below it.
When Eggman Nega is the pilot, the Egg Salamander turns upside down and has thin arms with three claws, giving it a more slender appearance. Its four-segmented tail is also now on the top.
After Blaze had collected all seven Sol Emeralds and beat Dr. Eggman, the disruption of the worlds seems to have ended, and she begins to ponder about how they restore the worlds and why she has not returned to her home, despite having all the Sol Emeralds. Out of nowhere, however, she hears Dr. Eggman and Eggman Nega mock her lacking knowledge about the Sol Emeralds and listens to their explanation about the connection between the Sol Emeralds and the Chaos Emeralds. The two Eggmen then appears in the Egg Salamander (Dr. Eggman's version) and they defeat Blaze, and drains the Sol Emeralds of their powers. Shortly after, however, Sonic appears on the scene, but the Eggmen merely leave in the Egg Salamander, preparing to crush them. Meanwhile, Blaze has given up all hope, since the Sol Emeralds have been drained, but Sonic makes her realize that the Sol Emeralds' power comes from people's friendship and gets her to embrace the friendships she has made, thus recharging the Sol Emeralds. She then becomes Burning Blaze and Sonic becomes Super Sonic, and together they face the Egg Salamander in Exception.
Finally, after a long battle, Super Sonic and Burning Blaze manage to bring the Egg Salamander on the brink of defeat. Eggman Nega claims to have another plan, while Dr. Eggman panics, and then Super Sonic and Burning Blaze deal the final blow to the Egg Salamander by charging at the same time at high speeds an slaming right into the Egg Salamander, destroying it in a large explosion.
Powers and abilities
The Egg Salamander is the strongest robot in Sonic Rush, and probably one of the most powerful robots in the entire Sonic the Hedgehog series due to possessing the drained energy from the seven Sol Emeralds. Additionally, the Egg Salamander is one of the few bosses that can injure super transformed characters by using specific attacks. Also, despite lacking wings, the Egg Salamander (in both forms) can fly in high speeds.
The version piloted by Dr. Eggman can launch mechanical satellites from its right cannon-arm that will circle around the opponent. This satellite can shoot blue energy lasers before eventually self-destructing. From its left cannon-arm, it can launch green energy balls that can move vertical on their own. Likewise, it can create swords of energy from its cannons and launch a barrage of rockets that are strong enough to injure a Super State user.
The version piloted by Eggman Nega can use its claws to perform avoidable claw swipes on the opponent and can grab the opponent from the distance. These claws' grib is strong enough to injure the normally-invulnerable Burning Blaze. It can also create a spatial rift into a dark void that suck everything into an environment that not even Burning Blaze can survive without getting injured.
The battle is split into five phases where the player alternates control between Super Sonic and Burning Blaze per phase who faces off against Dr. Eggman or Eggman Nega. As with most true final bosses involving the player using super transformed characters, the player's Rings will be drained at one ring per second; if the Ring count reaches zero, the player will lose a life and has to restart the fight.
The first phase begins with Sonic against Dr. Eggman. At the beginning of chase section, the player should collect as many Rings as they can while avoiding the asteroids; these can be destroyed with the Super Sonic Boost and the red ones contain Rings. Blue energy beams are always fired directly at Sonic at regular intervals. Once the player reaches Eggman, the Egg Salamander will fire two satellite-like projectiles that will orbit Sonic, firing blue energy lasers in four regular intervals that can knock Sonic back if hit. After a while, the satellites will flash red before exploding. To damage the Egg Salamander, Sonic has to deflect them back at the Egg Salamander's cockpit (which is its head) with the Boost. Eggman also fires green energy balls which fly out horizontally before making a sharp 90 degrees turn towards Sonic. These can also be deflected back at him. At other times, the Egg Salamander swings its energy sword from it's left cannon, which can be avoided with a well-timed boost. It will then fly into the background and fire a barrage rockets which Sonic has to dodge or lose five-seven rings when hit. After three hits, Dr. Eggman will switch with Eggman Nega, now controlling the mecha, to fight Burning Blaze.
As Burning Blaze, she can perform the Burning Fire Boost and generate fireballs, the latter of which she has to fire at Nega's cockpit to damage the Egg Salamander. The early chase section is nearly identical to the first one except Nega fires the energy beams much more rapidly. Once the player reach Eggman Nega, he will attack with fast slashes. Sometimes he will also hold out an open claw and fire it at Blaze. If the player can dodge this, it will leave him vulnerable to an attack. If the player fails to avoid the claw projectile, however, Nega will grab Blaze and hit her with the other claw, causing her to lose rings. Other times, he will go into the background and cause a spatial rift which will not only pull Blaze in, but also any rings nearby. To dodge the rift, the player must dash repeatedly until the rift disappears. Should the player fail to dodge this attack, the rift will immobilize Blaze and suck away up to twenty of her rings at the end. After three hits, Eggman Nega will switch with Dr. Eggman.
In the third and subsequent phases, the chase section is omitted but otherwise, Eggman and Eggman Nega's respective attack patterns remain unchanged, so repeat the above pattern five more times (on the fifth and final part for Sonic's phase, it takes three hits to defeat the Egg Salamander) until the Egg Salamander is defeated.
- This is the only boss battle in Sonic Rush (except for Egg Hammer Mega in Sonic's story), where the playable characters fight against their own respective Eggman; Super Sonic fights Dr. Eggman and Burning Blaze fights Eggman Nega.
- The Egg Salamander is one of the two bosses in Sonic Rush that can't be harmed by Sonic directly, the first one being the Egg Scarab.
- The Egg Salamander is the only boss in Sonic Rush to not have a Health Gauge be shown.
- The Egg Salamander has the most health out of any boss in Sonic Rush, as the Egg Salamander has ten hit points, unlike the other bosses, who have hit eight hit points.
- The attack that Super Sonic and Burning Blaze use to defeat this boss is used again in Sonic Generations when Classic and Modern Sonic defeat the Time Eater.
