"So cool! I haven't seen one of these things since the robot wars that killed everybody."

When colossal kaiju begin attacking from the sea, land, and air, humanity develops equally powerful mecha units to stop them in explosive hand-to-hand combat.

  • Aatrox MechaCircle Mecha Aatrox
    Chromaskins Chromas: Obsidian, Pearl, Tanzanite
    Designated ATRX-1, the “Mecha Aatrox” unit was developed in response to 'gliding' kaiju with the capability of limited flight. In addition, ATRX-1 wields a thermal blade that can turn residual light particles into a heated cutting edge.
  • Aurelion Sol MechaCircle Mecha Aurelion Sol
    Chromaskins Chromas: Amethyst, Catseye, Obsidian, Pearl, Rose Quartz, Ruby, Sapphire
    Designated ASOL-13, the “Mecha Aurelion Sol” is a gigantic, mobile mothership carrying tens of thousands of personnel, attack fighters, and ground-based anti-kaiju vehicles. Buried within its hull are a vast array of weapons, making ASOL-13 more than a match for even the most gargantuan kaiju.
  • Kha'Zix MechaCircle Mecha Kha'Zix
    Chromaskins Chromas: Catseye, Emerald, Pearl, Rose Quartz, Sapphire, Tanzanite
    Designated K-ZX, the “Mecha Kha'Zix” unit was the first of the mecha line to be deployed against the kaiju threat. Due to its smaller size, it functions best in urban environments, adapting on the fly to threats against civilian populations.
  • Malphite MechaCircle Mecha Malphite
    Chromaskins Chromas: Catseye, Citrine, Emerald, Granite, Obsidian, Pearl, Sandstone, Sapphire
    Designated M-2, the “Mecha Malphite” unit is a massive, bipedal fortress capable of turning into a planetary drill—making it the ultimate defensive option when faced with new and powerful kaiju. A single punch from its gauntlets can blow holes through thick titanium sheeting, and such attacks have felled countless monsters.
  • Rengar MechaCircle Mecha Rengar
    Chromaskins Chromas: Aquamarine, Citrine, Obsidian, Pearl, Ruby, Tanzanite
    Designated RNGR-7, the “Mecha Rengar” unit is the second stealth-based unit developed for urban combat. Bereft of its own warping technology, the RNGR can transform into a car for additional mobility.
  • Sion MechaZeroCircle Mecha Zero Sion
    Chromaskins Chromas: Catseye, Meteorite, Obsidian, Pearl, Rose Quartz, Ruby, Sapphire, Tanzanite
    The ultimate ground-based mecha unit, 0-SION becomes like a freight train once given a combat directive, and will literally stop at nothing to dismantle an opponent—no matter how much damage it takes. There are lingering concerns that it could go rogue, but so far these worries have been unfounded.



Mecha Promo

Prototypes have cleared all testing stages. TXN-9 components are stabilized and transformation protocols have been fully enabled. We will begin rolling out Sion OriginalSquare 00, Kha'Zix OriginalSquare 01, Malphite OriginalSquare 06, and Aatrox OriginalSquare 13.

Breach in protocol. Mechas are at 5.21% deviation. Prototypes will undergo corrective programming.

Mecha Zero profileicon 00 has rejected its reprogramming. All other prototypes have resumed service. 00 has been decommissioned indefinitely.

"Crush. Kill. Destroy."

All Out War


There were many prototypes, but I was the first and greatest success.

I crushed. I terrified. I destroyed.


I was wired for superiority, but the other units would not bow. My creators feared me.

They decommissioned me.


I will not be stopped. I will not be forgotten.

I will annihilate them all.

Mecha Rengar returns to the hunt

With a mechanical roar, Prototype Rengar OriginalSquare 09 crashed into the testing grounds; Prototype Kha&#039;Zix OriginalSquare 01 hovered above him, victorious but severely damaged. The lab abandoned 09 and documented their findings: the beast's construct proved inferior to the insect's.

But 09's internal memory would not let him forget. He was the true predator. And a true predator always returned to the hunt.


  • The concept for these skins was directly inspired by the movie Pacific Rim.
  • Sion MechaZeroCircle Mecha Zero Sion was hinted at 2 years before his intended release.
  • There have been 6 out of 14 Prototypes released, the fate of the other 8 is still unknown.
    • The prototypes numbers have been changed since the skins release. Aatrox MechaCircle Mecha Aatrox, Malphite MechaCircle Mecha Malphite and Rengar MechaCircle Mecha Rengar was prototype 13, 06 and 09 in their release pages[1][2], however, in their new bios, they are labeled ATRX-1, M-2 and RNGR-7.
  • It has been confirmed by Riot employees that both Battlecast and Mecha are two distinct universes separate from the universe of PROJECT and Program.[3]
    • However, while not being directly part of any other skin universe but its own, Pulsefire champions are able to traverse space-and-time, making them effectively able to be in all skin universes, including the main League of Legends universe.[4]
    • It has been hinted by Riot employees that Urgot GiantEnemyCrabgotCircle Giant Enemy Crabgot could be part of the same universe as the kaiju monster that the Yordles are fighting against.[5]
