It is not known to evolve into or from any other Pokémon.
It comes to life only when Regirock, Regice, and Registeel are gathered. Therefore, it requires the three to be in the player's party to awaken it within Snowpoint Temple, where it sleeps. It still appears on the map if they are absent, but does not awaken and the player regards it as a statue.
Regigigas shares several traits with the Regis. For instance, it has seven dot-like "eyes" arranged in a specific pattern. It has six spots that are apart from its eyes, which seem to be gemstones. These gemstones seem to represent the Regis with the red gems representing Regirock, the blue gems representing Regice and the silver gems representing Registeel. It has a golem-like shape and long arms with short legs. Its body is covered in black stripes, and it has moss growing in its back and feet, which may indicate it has been asleep for a long time.
Gender differences
Regigigas is a genderless species.
Special abilities
Regigigas has the ability Slow Start, which causes Regigigas's Attack and Speed to be halved the first five turns. According to its Pokédex entries, the legends say that its extremely high attack stat, combined with its colossal strength, enables it to move continents.
Regigigas is capable of communicating via telepathy.
Regigigas is also capable of controlling the legendary golems, even if they already belong to a Trainer.
Behavior
Habitat
It resides in the Snowpoint Temple, having done so for hundreds, maybe thousands of years. According to the braille in the Generation III games, it was sealed away in order to protect people, and three keys (the legendary golems) were created so that only one with the power of Regirock, Regice, and Registeel would be able to catch it.
Regigigas appeared in Giratina and the Sky Warrior. In the movie, it lives in a temple in the mountains of Gracidea. It had been asleep for centuries, for so long that moss began to grow on its body. However, when Zero entered the Reverse World and began shattering pillars of ice within it, the glacier in front of Regigigas' temple suffered catastrophic explosions and began moving. This disturbed the great titan's slumber, rousing it into action.
When Dawn's Buneary and Swinub failed to stop the glacier with the help of a large group of wild Pokémon, Regigigas appeared in the command of a herd of dozens of Mamoswine and together, they began pushing on the glacier to hold it back. Though at first they managed to still its movement and move it back slightly, in the end they too failed. It was only when Giratina healed the broken ice pillars in the Reverse World that the glacier stopped. Regigigas returned to its temple at the end of the movie, where it is seen using Hyper Beam on Team Rocket during the credits.
Another Regigigas appeared in DP129 at Snowpoint Temple. J wanted to steal it so it was rudely awakened by her. She shattered the pillars of ice, rock, and steel surrounding it and then she used her Salamence's Flamethrower on it. It went on a rampage after, using Hyper Beam on practically anything. It even used Confuse Ray to control Pyramid King Brandon's set of legendary golems to help it. At the end of the episode, it healed Brandon and his golems using Hidden Power to restore them from their petrification. It was then taken back to the temple to return to its slumber.

Due to its ability reducing its potential, Regigigas has more in common with Slaking than it does with other legendaries. They share the same base stat total of 670, the same base Attack stat of 160, and abilities that limit their power.
Although it is thought to be unique, it is possible to see and fight another, under the ownership of Palmer along with a Heatran and Cresselia in the 49th consecutive battle in the Battle Tower. Riley uses one too, possibly confirming that Regigigas is, like Cresselia, Heatran, and the other legendary golems, a more common legendary species than that of others.
It is the only Pokémon who can learn TMs that cannot learn TM17 (Protect) or TM44 (Rest). This is probably to prevent people from countering its own ability by avoiding damage or healing itself.
Regigigas is also the only one of the Regis that does not use the remix of the legendary golem battle theme in Platinum. Instead, it uses the legendary battle theme, much like in Diamond and Pearl.
Due to their typings, Regigigas and the other legendary golems all share a common weakness to Template:Type2 moves.
Despite being called the Colossal Pokémon, Regigigas is only the fourteenth tallest Pokémon and only the eighth heaviest.
Regigigas is one of only two Normal-type legendary Pokémon (the other is Arceus, but its type can change).
By hacking to get Cherish Balls, it is possible to trick the game into opening Rock Peak, Iceberg, and Iron Ruins: by catching Regigigas in a Cherish Ball, the game thinks the Regigigas was obtained at a Nintendo event.
