How big your pet came out

Rarity says how hard a pet was to find. Form says how many copies you burned to build it. Size is a fourth thing again: how big the pet came out, decided by its own die and by nothing else.

Most pets are base size. A few come out Big, fewer are Giant, and a Titan is among the rarest things the game produces. Whatever a pet rolls, it keeps for good.

Size is not a form

The size die is rolled once, at the moment a pet is created, and the result is fixed for the life of that pet. Nothing moves it up or down afterwards, and no upgrade converts a Big into a Giant.

It also does not travel up the form ladder. Feed a Giant copy into the Evolution Hub and the pet that comes out rolls its own size from scratch, which is almost always base. The machine asks you to confirm before it eats a sized copy, because that really is the end of it.

The three sizes and their odds

Power and net worth move together on this axis, on purpose. A Titan is worth eight times a base copy on both counts, which is a bigger single jump than any form step below Astral.

The three things that bend the odds

Three sources feed one shared dial, and they add together rather than multiplying. Everything else in the game is deliberately kept away from this die, including the extra luck a Charged Egg buys.

• The EGGZILLA gamepass, the largest of the three.
• Titan Attunement on the destiny branch of the Supernova tree, three levels deep.
• The Growth Study research, the small early one.

Where the die gets rolled

Any moment the game creates a new pet rolls it: a normal hatch, an auto hatch, a batch coming out of the Nest, a fusion result in the Evolution Hub, and the pets that come out of special boxes.

Landing a Big, Giant or Titan for the first time earns a badge you keep on your profile, and each size carries its own label on the pet card so you can spot it in a crowded collection.

One thing worth knowing: the size draw itself is a switch the team controls. While it is off, newly created pets all come out at base size. Nothing is stranded when it moves either way, because any pet that already rolled a size keeps that size, its power and its net worth.
