Death Egg Robot/Supermystery's version

Referred to as Metal Eggman in-game, this is a boss character which is as faithful as the source game as possible, possesing the same attack pattern as seen in Sonic the Hedgehog 2 and having hurtboxes on the spikes on its arms, though it can also be controlled by the player.

Gameplay


As expected, this character is a boss character and sports the same moveset as its incarnation from Sonic the Hedgehog 2. Strangely, it is reffered to as Metal Eggman, despite the fact that the name Metal Eggman was never given to it in official media. Like in Sonic the Hedgehog 2, its only weak spot is its belly and touching the spikes on its arms will result into taking damage.

When controlled by the A.I, it slowly walks forward. The player must be very careful when attacking it, because when you hit the spikes on its arms, you will take damage and get knocked back. After some time, it takes off and flies into the air. Then, a lock-on target will appear on the player. When it starts flashing, Metal Eggman will slam down. It's very easy to avoid this attack, but if you do get hit, you take huge damage. Sometimes, it will drop three Robotnik-shaped bombs while taking off. These are very hard to avoid since the time between the moment when it takes off and moment where it drops the bombs is very small. It's best to block this attack, though the bombs will scatter two pieces of shrapnel to the left and right of them when they explode, which should also be blocked. After Metal Eggman slams down, it will sometimes fire its arms at you. You can run away from it to avoid it, but it can also be blocked or jumped over. The best way to deal with this boss is spamming projectiles, as you can safely spam them while it's walking. The difficulty of the boss depends on the size of the stage, because when the stage is very small, it becomes much harder to run away from the boss.

This character can also be comtrolled by the player, having a very simple moveset. Most A.I-controlled characters will fail to beat this character because most of the time when they attempt to attack, they will hit the spikes on its arms and usually get crushed by Metal Eggman when it crashes down, making fights as Metal Eggman a breeze.

While it's as source-accurate as possible, there are still a few differences. Metal Eggman drops three bombs instead of two and drops them while taking off, as opposed to dropping two after crashing down when the player is behind it. Also, the creator stated it wasn't possible to bind the jet because of the way the sprites were ripped.
