Shimo (霜 Shimo, lit. "Frost") is a reptilian ancient monster that holds chilling power over cold temperatures which made her a dangerous force of the Hollow Roblox. Shimo was made an unwilling "slave" of the Skar King and forced to obey his commands, assisting him in his plot to dominate the entire planet. She was eventually freed through the combined efforts of Godzilla, Kong, and Suko, which allowed her to take revenge on her enslaver.
Personality
Despite her past of wreaking havoc and triggering the previous Ice Age, Shimo's true nature is a peaceful and benevolent Titan whose violent actions actually come from being coerced to do the Skar King's bidding. She resents the Skar King deeply for his mistreatment and control, defiantly roaring in her attempts to resist his orders. Shimo also demonstrates a reasonable level of intelligence: when the Skar King's control over her is broken, she acts swiftly, freezing the Skar King solid, and thus allowing Kong to deliver the final blow. This highlights discernment, loyalty, and ability to make choices aligned with her own values. Once free, Shimo instinctively chooses to be with Kong and Suko, forming a strong bond. She affectionately nuzzles Kong and delights in being petted, finding joy in their companionship.
Origins
Shimo was a very ancient and extremely powerful Titan that used her powers to alter the climate of Roblox. Several cultures in the South Telamon call Shimo "The Monster Whose Breath Makes the Ocean into Stone". It is theorized that Shimo is a former Alpha Titan, and based on ice analysis, Shimo may have aided Godzilla in freezing and imprisoning Ghidorah in Bloxartica. Cave paintings also suggest that Shimo attempted to challenge Godzilla at some point, before he defeated her and made her submit.
According to Iwi prophecy, Shimo at some point became enslaved by the Skar King. Eventually, Godzilla fought, defeated, and imprisoned the Skar King and his army of enslaved Great Apes, Shimo included, in the depths of the Hollow Roblox.
Abilities
Bio-cryokinetic nature
Shimo possesses thermo-regulatory physiology, able to manipulate the ambient temperature to below freezing. In addition, her mere presence can freeze objects around her such as the ground, minerals, plants, and water. Her touch was shown to even freeze volcanic caverns like the one the Skar King locked her in. However, riding on her back does not cause the Skar King and Kong to get frostbite, which implies she has complete control of which parts of her body can cause freezing.
The mechanics of Shimo's cold generation are that she produces a unique form of radiation which slows atomic movements down in their tracks, described as "the essence of cold".
Environmental cooling
Shimo is theorized to be directly responsible for triggering Roblox's last Ice Age, which continues to affect Roblox's climate to the present day via glaciation periods.
According to Monarch research, Shimo is indicated to have flash-frozen the entire Ro-Greenland landmass into its present day arctic state within an extremely short amount of time. Monarch suspects that Shimo may be powerful enough to have triggered earlier, much more intense Ice Ages in Roblox's past, and that she could cause a Snowball Roblox if her powers were activated to their fullest potential.
Frost bite blast
Shimo is capable of unleashing a potent, concentrated beam of freezing ice from her mouth known as a "frost bite blast". This beam has extremely low temperatures, capable of freezing immensely strong Titans such as Godzilla and the Skar King completely solid with Godzilla needing Mothra to help him break out. It also is able to inflict Kong's right arm with severe frostbite and become temporarily numb, which is quickly recovered by a B.E.A.S.T. Glove, a metal brace constructed by Monarch through Project Powerhouse.
When Shimo fires her frost bite blast to the sky, it creates a monolithic blizzard that could only be quickly dispersed by Godzilla's atomic breath. This is supposedly what she did to start the last Ice Age. Her frost bite blast has also shown to leave large amounts of ice along anything hit by it, the ice being strong enough to stop two moving Iwi pyramids and prevent them from colliding momentarily.
Durability
Shimo possesses one of the most substantial levels of durability among the Titans. She was able to withstand being shot by in the stomach by Godzilla’s atomic breath. Shimo was later able to survive prolonged exposure to Godzilla's supercharged atomic breath, which was far stronger than that of his normal atomic breath, while he was aiming at her neck and she came out, seemingly with little injuries. This stands out to most other creatures, who would be severely injured or almost killed by even being hit by Godzilla's normal atomic breath.
Shimo has shown to be capable of withstanding physical attacks from Godzilla who had developed increased strength due to his evolution. Despite her cold nature, she appears capable of withstanding or enduring high temperatures, as being locked in volcanic caverns by the Skar King shows having no ill effects on her. Shimo, like all titans can survive gravitational inversion, a planet worth of gravity reversing in a split second.
Speed and agility
Despite her immense size, Shimo can run on all fours and fast enough to catch up to Godzilla. Her tail is also swift enough to prevent Kong from attacking the Skar King.
Strength and combat
Shimo is shown to be a strong Titan, with even Kong and Godzilla—who had gained a boost in power after consuming large amounts of radiation—facing a challenge with her in physical strength. She was able to grapple and push Godzilla backwards, and even managed to kick the heavy Titan into the air after he tackled her when she attempted to attack Kong. Kong also had great difficulty defending himself from Shimo as she grabbed him by his right arm and threw him through buildings. She subsequently used her jaws to effortlessly lift and swing Kong away. Shimo can also use her tail offensively, as she did with Kong to keep him away from the Skar King during their battle at Rio de Bloxeiro. Shimo can also endure large amounts of weight, as she carried the Skar King on her back, and later, the combined weight of Suko and Kong while the latter was wielding both his battle axe and the B.E.A.S.T. Glove.
Weaknesses
Skar King's crystal
Shimo became enthralled by a special blue crystal used by the Skar King. Being under the influence of the crystal visibly causes Shimo discomfort, and she can be forced to perform any order the Skar King commands. Shimo is eventually freed from the crystal's effects after Suko used Kong's battle axe to destroy it in Rio de Bloxeiro.
