Muscle Transform Simulator Players Hub

Muscle Transform Simulator is a live Roblox incremental from Castaway Studios RBLX with a short, named roster in each world. You start skinny in the lobby, press F to transform, train arms, legs, and body, then smash the online city for Gold. Gold buys the next character. Max every character in a world and the Worlds menu opens the next map. This hub is the roster map: who exists, how they unlock, and which wiki page holds the details.

The game is free-to-play, online, and running on ten-player servers. Other people smash the same props you smash. That does not change the unlock rule. You still buy bodies in order. You still train each one to capacity. Premium forms such as Venom, King Hulk, and Master Rage sit in the same character shop as extras, not as a skip ticket.

Where to go from this hub

Use Transformations when you care about the F key, the Venom kit, Hulk looks, King Hulk, and Master Rage. Use Worlds and Roster when you care about the World 1 through World 5 line, Gold costs, and the new egg stand that appears on each map. Use the character tier list when you already know the names and want smash order. If you just spawned, start on Getting Started so training, smash, and the first Gold weights happen in the right sequence.

We only print names we can confirm. World 1 is Rage Man, Gray, and Spike Man. World 2 is Warrior, Baldy, and Hero, the anime-looking trio that videos often call Goku, One Punch Man, and All Might. World 3 is Cake plus odd forms. World 4 is Galaxy Creature or Galaxy Guardian, Money Man, and Void Guardian. World 5 is Gladiator, Warrior, and Dark Warrior. Premium names are Venom, King Hulk, Master Rage, and Mysterious Hulk on the daily wheel. If a shop slot is not in that list, this wiki does not invent a label for it.

How the roster actually unlocks

Each world sells its bodies in order. Finish the current character’s three bars, pay the Gold, equip the next body, transform, and train again. When the last body in a world is complete, the next world is the reward. Eggs, weights, potions, and rebirth all sit around that ladder. They make the ladder faster. They do not remove rungs.

Rage Man is the teaching form: the green Hulk-like look that sells the thumbnail. Gray is the mid step. Spike Man closes World 1. Later worlds shift the art: anime in World 2, odd forms in World 3, galaxy in World 4, gladiators in World 5. Read those as themes, not as factions with hidden quests.

Pets hatch from lobby eggs and from world eggs. Weights buy in order with Gold, then Galaxy around 500 Robux, then Titanic limited weights later. Rebirth is the loop after a roster is complete. Auras are a live overlay. None of those systems add extra named fighters. They only dress the bodies you already bought.

How to read the lineup during a session

Open Characters when you have Gold and a finished bar. Open Worlds when a closer is done. Smash on the body that prints Gold, even while the shop still wants an older bar filled. The roster is a shopping list. The equipped transform is a tool.

Treat the roster as a ladder you must climb, not as a collection you can skip. Climb the five live worlds in order. Do not stall on Rage Man because the green look still feels like the mascot. Every live shop body still wants Gold and a full set of bars before the next map opens.
