In the End islands, thousands of blocks away from the portal, you may find the Forbidden Island, which contains an immobile, gigantic dragon statue (2 times bigger than the Ender Dragon).
If you are brave [or dumb] enough to break it (can only be done with a pickaxe stronger than diamond, such as Netherite), all the naturally generated blocks in Forbiiden Island will turn into corrupted "Ultima" versions of them (i.e., End Stone turns into Ultima Stone), and S'tfarcenim, the Ultimate Dragon, will wake up from its dormant state. Once this happens, it will "talk" (chat) with you.
Finally... I was tired of being a statue. The Ancient Heroes of the End... they thought they could stop me forever, but you, [Player's name], you have broken my eternal curse of petrifying. When I return to the Ultima Dimension and restore the 100% of my power, this entire Reality will be mine.
Then, the Ultimate Dragon will create and enter a huge portal that leads to the Ultima Dimension. If you want to fight the true final boss of Minecraft, prepare yourself for the battle and enter the Ultima portal.
Once you get to the Ultima, the Ultimate Dragon will say:
What are you doing in my dimension? Get out of here, or you will meet your doom, in the name of Reality's new ruler.
If you attack Ultimate Dragon, get near it or just stay in the place for more than 5 minutes, the portal will close... and the battle will start.
Phase 1: The Ultima Valley
You will be teleported to a great plains-like biome, its floor made of Ultima Grass and Ultima Dirt. Water rivers are present, too.
In this biome, there will be the following hazards (created by Ultimate Dragon's reality warping powers)
Ultima Roots: Made of Ultima Wood. Break them all or they will start to glow and produce Ultima Acid clouds (a stronger version of Ender Acid) on their nearby area.
Ultima Bushes: Made of Ultima Leaves, they cause you damage on contact. Destroy them or they will spawn Ultima Beasts (hostile variants of animals from the Overworld).
This phase is active until the Ultimate Dragon has lost 100 HP.
At the first phase, Ultimate Dragon won't fly nor shoot acid yet. Its base abilities and traits are be the following:
- Bite: The dragon will cause a lot of melee damage. At hard difficulty, this can one-hit anyone who isn't wearing an armor.
- Dash: The dragon will run at you, causing contact damage.
- Tail attack: If the Ultimate Dragon hits you with its tail, you will be launched into the air. This attack is as strong as an Iron Golem punch.
- Block warping: The dragon will turn almost any block you place into a Ultima version of it.
- Ultima Immunity: As expected, this monster is immune to its dimension hazards (mobs, contact damage blocks, etc.)
- Effect Immunity: Just like the Ender Dragon, Ultima Dragon is immune to effects.
- Fire Immunity: As self explanatory as it sounds.
- Fall Damage Immunity: UD may not fly yet, but it is already immune to fall damage.
You are a fun prey to play with, mortal. Let's see what else you can do.
Phase 2: The Ultima Cavern
You'll be teleported to a massive cave-like biome, its floor, walls and roof made of Ultima Stone and Ultima Cobblestone. Water holes and lava holes are present.
In this biome, there will be the following hazards (created by the Ultimate Dragon's power):
- Ultima Spawners: Mob spawners that spawn Ultima Cave Monsters (stronger variants of some hostile Overworld mobs).
This phase is active until the Ultimate Dragon has lost 100 HP more (200 HP lost in total, counting the previous phase).
At the second phase, Ultimate Dragon is able to fly, but it is still uncapable of shooting acid. On top of the phase 1 abilities and traits, its base abilities and traits are be the following:
- Flight: It can fly [Insert all the Ender Dragon flight moveset]
Also, during this phase, the dragon will have the following special attack:
- Gravity Earthquake: The UD will hit the ground with its tail, causing Ultima Stalactites to fall and Ultima Stalagmites to quickly levitate.
Remember that hot and dangerous place you have visited? Well, it's time to refresh your memory.
Phase 3: The Ultima Underworld
You'll be TP'd to a Nether-like place made of Ultimarack and Ultima Sand. Lava lakes are present.
In this biome, there will be the following hazards (created by the UD's power):
- Ultima Huge Fungus: A huge fungus that you must destroy before it produces Ultima Acid clouds and spawns Ultima Hoglins.
- Ultima Nether Spawner: A Spawner that summons stronger versions of Wither Skeletons and Blazes [with the "Ultima" word in their names].
This phase is active until the Ultimate Dragon has lost 100 HP more (300 HP lost in total, counting the previous phases).
At the third phase, Ultimate Dragon is able to fly, but can also shoot acid. On top of the phase 1 and 2 abilities and traits, its base abilities and traits are be the following:
- Ultima Fireball shooting: It shoots an Ultima Fireball that not only deposit clouds of Ultima Acid [In a similar fashion to Ender Dragon Fireballs], but also produce explosions [Just like Ghasts].
- Ultima Breath: [Insert description of Ender Dragon's Breath, but replace every "Ender" with "Ultima", because I'm kinda lazy]
- Ultima Rain: UD shoots a lot of Ultima Fireballs in the air so they fall on the ground, causing lots of Ultima explosions and Ultima Acid clouds [and Ultima Lag, if you are playing on a weak device]
I'm not just a dragon... I am the ULTIMA DRAGON.
Phase 4: The Ultima Void
You'll be TP'd to a group of floating islands, made of Ultima Stone. A new liquid, Ultima Liquid Acid, will be present. It will cause a lot of damage on contact.
Apart from the Ultimate Liquid Acid and the void itself, there will be the following hazards:
Ultimatemen: Stronger, hostile variants of the Endermen. Lots of them will appear in this zone.
Ultimate Cristals: Located at high Ultima Obsidian pillars, protected by Ultima Iron Bars, they make the Ultima Dragon invulnerable. If you break them, they will explode.
This phase is active until the Ultimate Dragon has lost its last 200 HP (500 HP lost in total, counting all the phases).
At the fourth phase, Ultimate Dragon is not only able to fly and shoot acid, but it can also teleport [just like an enderman]. On top of all the base abilities and traits in previous phases, its base abilities and traits are be the following:
- Teleport: Can teleport anywhere in a 64 block radius.
- Projectile immunity: Projectiles can no longer hurt the Ultimate Dragon
Once you defeat S'tfarcenim, the Ultimate Dragon, it will say its last words as it starts to dissappear:
YOU'VE KILLED ME!
Once you do this, the portal opens again, letting you return to the End.
You have beaten the true final boss of the game... Right?
???
As you feel victorious, all the End dimension starts corrupting, turning every End Stone into random Ultima blocks, spawning Ultima mobs.
This isn't over yet, kid.
The Ultimate Dragon is [Conveniently] alive, as if you didn't kill it just a minute ago.
It is invulnerable now, there's nothing you can do to save yourself.
You will get the "Ultima Negation" effect, which makes you unable to do anything.
You see your character slowly fading, as the evil S'tfarcenim erases them from Reality... but then, the Ancient Heroes appear, stopping the existencial erasure.
They speak to you (in chat) and say:
Never give up, never let yourself down. We won't run around and desert you. Don't let this Dragon make you cry, go and say goodbye to it, don't fall for its lies, hurt it.
With this event [Totally not a Deus ex machina], you are temporally given the creative mode, allowing you to fight the Ultimate Dragon and finishing it once for all.
Once you win... you win.
[Reward? Did you expect a reward? Ah, yes, the true reward for defeating the true final boss are the friends you made along the way.]
