Void Muscle HYDRA Pets, Eggs, and the Items UI
Hatch on purpose. The Items page is where accounts are won or deleted.
Pets are the multiplier that survives a rebirth. Machines are the hourly wage. If you only lift, you will watch Hydra owners pass you on the same bench. This page is how Void Muscle HYDRA pets actually work: the Items grid, egg types, luck, slots, and what to lock before you fuse.
Use it with the pet tier list, Hydra, Void Crystal, secret egg, and hatch planner. The mid-article video is a live pet hunt, not a thumbnail flex.
The Items UI
Open Items on the left stack. Pets paginate (Page 3/6 in current builds). Each card shows a level, XP bar, and the stats it grants while equipped — Strength, Durability, sometimes Damage, Gems, or Rebirth. Rename exists. The equipped preview sits on the right (Cursed Void Bunny is a common early Void-line example: a few thousand Strength and Durability at level 1).
Rules:
- Equip the highest Strength + Durability combo you own for grinding.
- Keep a Damage pet only if you actually PvP or clear a boss gym.
- Gems-on-pet and Rebirth-on-pet are late-game (Hydra territory).
- Do not rename a pet you might trade. Traders filter by default names.
Egg types you will actually see
- Shop eggs — gem priced, always there, mostly filler. Fine for the first hatch after Getting Started.
- Void Crystal / secret crystals — Gold Coin, limited, Void-line. Void Crystal.
- Divine Egg — a separate “big secret” hunt in creator videos. Treat it as limited. Do not dump gems into it until a patch note confirms it.
- Pack eggs — Chaos Overlords Pack and Multiverse Muscle Pack live on the Roblox passes list. Ranked on gamepasses.
- Event / new-gym eggs — Infernal Gym era adds themed rolls. Track new gyms.
Chat saying “this is the new egg” is your cue to stop auto-hatching the old crate.
Luck, 3x Hatch, and slots
Luck from codes, Fortune, and passes changes rare rolls. 3x Hatch is the pass that actually multiplies a limited crystal. Buy it when a crystal is live and you have coins, not on a Tuesday shop egg. +2 Pet Slots and +20 Capacity are quality-of-life so you stop deleting Hydra food. All three are on the gamepass tier list.
What to keep vs delete
Keep:
- Anything Void-line or Hydra-line, even at level 1
- Pets that beat your current equipped Strength by a real margin
- Duplicates needed for evolves (Hydra eats copies)
Delete or trade:
- Starter join pets once you have a Void-line
- Tiny-stat fillers occupying slots during a crystal window
- Green Golem style commons unless they somehow beat your main (they will not)
The pet tier list is the S–D snapshot. This page is the inventory hygiene.
Bugged and admin pets
There are videos of bugged pets and admin-abuse hatches. Those stats do not survive patches. The title already went DATA FIXED once. If a pet looks illegal, screenshot it, do not build your whole rebirth plan on it. Data-fixed and script safety apply.
Equip loadout while grinding
Fill every slot. An empty slot is a missing multiplier. Prefer Strength on training days, Durability if you keep getting punched off the Infernal pad, Damage only for brawl quests. Then sit the gym ranked on gym tiers. Pets do not replace rebirth training — they make each rep worth more.

Frequently Asked Questions
Quick answers to the most common questions.
How many pets can I equip?
A small base number, plus the +2 Pet Slots pass. Capacity is separate and only stops deletions. See gamepasses.
Should I hatch or buy from Trade?
Hatch limited crystals yourself. Trade only duplicates you understand. Scams live on the Trade button.
What is a Void-line pet?
Pets from the Void Crystal and void-themed eggs (Cursed Void Bunny, Deepvoid Hunter). They feed Hydra evolves.
Do pets persist through rebirth?
Yes. That is why hatching beats hoarding Strength. Rebirth still matters — rebirth training.
