Omni-Mobs adds some powerful and overpowered mobs into Minecraft for mob battles.
- As of version 0.1.3, no additional mods are required.
- You can disable music, camera shake, and the coremod, in the config. Disable the coremod if you have problems with launching the game. (It should be okay now though.) Coremod is used for:
- Metapotent Flashfur's enhanced defence.
- Defence against Mixins.
getHealth()modification defence.
- The mod currently does not work on servers. LAN might work, but it isn't tested often.
- This mod is still in alpha. There may be bugs, and anything might be changed at any point!
Mobs
Common Boss Entity Features
"Boss Entities" (`BossEntity`) refer to every mob except Metapotent Flashfur. They are still normal entities, but they override many core game systems.This Includes:
- "Absolute" Defences: While they can't be truly absolute, Boss entity defences are immune to
DATA_HEALTH_IDsetting, setter-method invoking, and field/EntityDataAccessortraversal. - Immunity Bypassing: Boss entities bypass conventional defences such as damage caps and custom health.
- Set-Target Immunity: Boss entities cannot be forced to switch targets.
- TP Immunity: Boss entities are immune to
/tp,teleportTo(),setPos(), andsetPosRaw(). - Despawn Immunity: Boss entities are immune to being removed from existence by methods such as
discard(),remove(),setRemoved(),levelCallback.onRemove(),EntitySection.remove(), etc. - Other Random Immunities: Boss entities are also immune to
getNavigation.stop(), freezing,setNoAI(),setNoGravity(), potion effects, and more.
Flashfur

Appearance:
A black and white cat with blue eyes. He wears blue clothes, and is twice the size of a normal Minecraft cat.
Powers/Stats:
- Supernatural Condition: Flashfur is far faster, stronger, etc, than a normal cat.
- Health: 750.
- Damage Reduction: 95%.
- Damage Cap: 2% max health (15).
- Invulnerability Detection: Bans healing and erases entities if invulnerable or not taking much damage.
- I-Frames: 10 ticks.
- Weak Damage Negation: ~0.02667% max health (0.2).
- Regeneration: 0.01333333% max health (1) health per second.
setDeltaMovement()Resistance: 100% (immune).
Offence Moves:
- Swipe: Flashfur will swipe at his target, dealing 75 + 10% max health damage to entities in a 1.5-block radius.
- Ground Slam (Shockwave Generation): Flashfur will slam his paws on the ground, creating a massive explosion that deals 1500 + 50% max health damage, and affecting entities in a 1500-block radius, getting weaker by distance.
- Super-Speed-Slashes: Flashfur will fling entities into the air, and will slash them every tick (1/20th of a second) for 100 ticks, each slash dealing 5 + 1% max health damage. During the 100 ticks, entities cannot move, and Flashfur is invisible (to simulate the fact he is moving so fast, you cannot see him).
- Supernatural Speed: Flashfur will run towards his target, reaching them instantly. Entities caught in the speed trail take 100 + 1% max health damage, and are flinged into the air. He will sometimes do this a bunch of times in a row.
Defence Moves:
- Dodge: 80% chance.
- Jump Dodge: Flashfur will sometimes dodge damage by jumping out of the way.
- Rolling Dodge: Flashfur will sometimes dodge damage by rolling out of the way.
- Backflip Dodge: Flashfur will sometimes dodge damage by backflipping away.
Other:
- Sometimes Flashfur will sit down, when not attacking anything.
Metapotent Flashfur

Appearance:
Flashfur just looks like his normal self, but he is 10 times larger, he has moving purple and ice-blue lines on him, and he has purple and ice-blue light rays coming off him. He also has stars around him.
Powers/Stats:
- Metapotence: Flashfur can do absolutely anything/everything with no limits (sadly not actually possible in a Minecraft mod).
- No Health: Flashfur doesnāt even have a health value. (It displays as Absolute Infinity on the bossbar.)
- Absolute Invulnerability: Flashfur cannot be damaged, at all.
- Anti-Regeneration Damage: Mobs cannot regenerate damage taken from Metapotent Flashfur.
- Immunity Bypassing: As well as normal "damage-based" immunity bypassing, Flashfur also ignores various types of despawn immunity, such as overriding
remove(), or Mixin-cancellingremove()methods in the core entity storage classes ā he directly wipes entities from the game. - Render/Non-Entity: Flashfur is not a normal entity, and is not saved as a normal entity, meaning no entity erasure methods can even target him. He has a connector entity following him around, but if it is deleted, another one will appear (he can function without it).
- Fast Targeting: Flashfur has no targeting delay. He can instantly target entities.
- Infinite Follow Range: Flashfur has infinite follow range, and can see entities that are on the other side of the world.
- Forge Event Independence: Unlike a lot of other non-entities (e.g. Dragionn), Metapotent Flashfur doesnāt rely on the Forge event system. (Unless the coremod fails. In that case, he will use events as a fallback.)
- Event Bus Override: Flashfur will take over
MinecraftForge.EVENT_BUSand prevent certain events from firing. He also disables shutdown of the event bus. (This should be safe, and the original event bus should be restored when Metapotent Flashfur isnāt in the world.)
Moves:
- Meta-Swipe: Flashfur will swipe at his target, creating a small purple and ice-blue explosion, dealing infinite damage to all entities in a 20 block radius. If the target somehow doesnāt die from this, they will be instantly erased out of existence.
- Omni-Erasure: Flashfur will wave his paw, and every loaded entity, no matter the distance, will be erased from existence.
- Totality Boom: Flashfur will make a massive explosion, dealing infinite damage to all loaded entities, and erasing them if they survive.
- Meta-Beam: Flashfur will summon a beam, that will hit the target instantly, with 100% accuracy, dealing infinite damage and erasing them if they survive.
- Meta-Explode: Flashfur will fling all loaded entities upwards, and then he will summon an explosion on them, dealing infinite damage and erasing them if they survive.
- Meta-Teleportation: Flashfur will teleport to his target if they are more than 60 blocks away.
Iron Golem

Appearance:
A regular Iron Golem from Minecraft, but with bends and better animations.
Targeting:
By default, the Iron Golem targets everything, but priorities villagers over other mobs.
Powers/Stats:
- Supernatural Strength: The Iron Golem is very physically strong.
- Enhanced Durability: The Iron Golem is far more durable than a normal golem.
- Health: 200.

- Arm Bash: The Iron Golem will bash targets with his arms, dealing 5% + 20 damage. It has an AOE radius of 3 blocks. He sometimes bashes with both arms.

Powers/Stats:
- Health: 50.
- Damage Reduction: 90%.
- Damage Cap: 10% max health (5).
- I-Frames: 10 ticks.
- Regeneration: 0.5% max health (0.25) health per second.
- Weak Damage Negation: 0 (none).
setDeltaMovementResistance: 0% (none).
Moves and Abilities:
- Sword Slash: Alarm will attack with his enchanted netherite sword, dealing 5% max health + 11 damage. This also has a 1.5 block AOE radius. If he is falling, he can also perform critical hits, that deal 1.5 times more damage. You can give him other items with /item and he will use it as his main weapon. You can even make him fight with his fist!
- Bow: Alarm will shoot an arrow with his bow, dealing 5% max health + 8 damage. This takes a second to draw back, and it doesnāt have infinite range (gravity exists). If he is close to his target, he will flip backwards and then use it. Good for long range attacks.
- Water Bucket Clutch: If Alarm is falling from more than 3 blocks high, he will catch himself with a water bucket, negating the fall damage, like an actual player.
- Parry: Alarm has a 50% chance to parry attacks.
- Dodge: If the attack is not parried, Alarm also has a 50% chance to dodge attacks. He will jump to the side.
- Sprint Jump: Alarm will sprint and jump towards his target, meaning he moves faster, just like a normal player would.

- Lightning Shockwave: Silverlight jumps into the air, and when landing, summons 3 low-powered lightning bolts in the direction he is looking. Each lightning bolt deals 25 + 5% max health damage. He will either front-flip or back-flip, depending on how close he is to his target.

Items
Entity Remover
The mod adds an Entity Remover, which looks like a pink sword. You can remove a single entity by left-clicking on it, and you can remove all loaded entities by right-clicking.
If you shift-right-click, it'll open the config GUI. This has:
- Run
die(): When this is on, the Entity Remover will run thedie()method on the entity, in case the entity uses it for cleanup. - Leave-Level Calls: When this is on, it'll remove the entity while running all events and calls that happen when an entity is normally removed (e.g.
onRemovedFromWorld()). When this is off, it won't run these. - Teleport Entity: When this is on, the entity will additionally be force-teleported to x=1,000,000,000, y=0, z=0.
- Invulnerability: This will make you immune to almost all damage, such as
setHealth(),hurt(), andDATA_HEALTH_ID. - Immovability: This attempts to make you immune to being teleported or moved around, but it currently doesn't work properly.
/kickBan: This prevents you from being/kicked. This is useful if a mob from another mod tries to kick you for whatever reason.
Future Plans:
General:
- Re-add some more Dragionn's Stuff mobs.
- Multiversal Dragon might be added, but I was having some issues with rendering a massive model (10,000,000 blocks long).
- Ashfire may be added in the future.
- Greylight may be added.
- Annihilation Emperor might be added. (He might have the same issue as Multiversal Dragon, as I want to make the spaceship 100,000 blocks long.)
- Add some other new mobs.
- Possibly a shadow-themed cat around Silverlight's level.
- Possibly another player-like mob, that's weaker than Alarm.
- Rework Alarm.
- Make it so he stops and eats golden apples to regenerate, instead of passively regenerating.
- Maybe make his aim better when he uses his bow.
- Maybe give him an elytra, so he can fly around.
- Maybe give him more weapons (tridents, crossbows with fireworks, end crystals, etc).
- Rework Flashfur.
- New moves and better visual effects. I might make the explosion not obstruct the player's view as much.
- Maybe allow him to parry attacks like Alarm can.
- Change his speed visual effect to something more performant, so I can make him faster (if I make him faster now, too many speed visual effects will appear, and it'll lag the game).
- Make Iron Golem's animations smoother, as they currently snap to different animations.
- Possibly rework Metapotent Flashfur again.
- Substantially increase Metapotent Flashfur's attack power with attacks that edit code and ban entity spawning, as pure-erasure-based attacks aren't very strong against powerful mobs. I might also prevent leave-level calls from running.
- Make Metapotent Flashfur immune to other extremely OP mobs, and immune to coremods/Instrumentation agents that inject
return;s/remove his ticking/rendering code. (This is usually how other mobs beat him right now.) - Make Metapotent Flashfur's Event Bus Override stronger, by preventing other mods from overwriting his changes.
- Make the code cleaner. (Long-term goal.)
Bug Fixes:
- Fix Metapotent Flashfur not working in LAN worlds.
- Fix other random bugs. (The mod will probably always have at least a few bugs.)
- Get the mod functioning correctly on multiplayer and not crashing on dedicated servers. (This is not a priority, as it will require major changes, and the mod is mostly designed for singleplayer.)
