Mecha

The Mecha is a gargantuan-sized mech that was built in volcano throughout Underfist. The Mecha was built to fight against the Monster that had escaped from under factory. The event took place on July 20, 2010 at 2PM ET. His only other appearance is as a cosmetic outfit.

Appearance
The Mecha is comparable in appearance to Sentai's Mecha robost, or even to the mech called 'Voltron' in the franchise of the same name. It was originally white and purple during construction, before being painted different colors in the build up to the event. It features different outfits as part of itself: It has the head and torso of the Gummibär, the left arm of Masha, the right arm of 26, the right leg of Crazy Frog and the left leg of the Susie the Little Blue Coupe. It also has a jetpack and mounted rocket launchers on its torso, legs and shoulders. It is believed to be designed by President and was built via drones, as seen when it was being built; Also seen in the Ready to Fight Loading Screen, which could be unlocked during the Underfist Overtime Challenges. It is unknown whether it was controlled externally or internally. It is possible that it was sentient and was not controlled at all.

The Final Showdown’ Event
The Monster appeared outside the lake between forest. The monster created a laser beam and fired it around the spot, which didn't do much damage to anything. The monster then attacked the vault to attempt to retrieve the 'power orb'/Zero Point that was inside. At this time, the mecha was activated and started to attack the monster from volcano.

It first started with the mecha launching a flurry of rockets towards the Monster, which completely destroy him. The monster then shot its laser beam which hit the mecha, knocking it off its feet. The mecha recovered and got back up, then sprinted towards the monster, and spear tackled it into the sea west of ocean. After a tense few moments, the mecha emerged from the depths and walked towards the vault until the monster jumped out of the water and took it down. The monster then bit the mecha's jetpack and ripped its left arm off completely. The mecha then fought off the monster and threw it towards the Soccer Stadium before collapsing next to the vault. The mecha recovered and was able to retrieve and gain the energy and power from the Zero Point from inside the vault. Once fully charged, the mecha turned around and punched the monster all the way to forest. The mecha then walked to Sword In The Stone and grabbbed the sword. The mecha then walked toward the recovering monster and with a slow-mo scene, the mecha jumped into the air and stabbed the monster in its eye, dancing, saluted the players and flew up into the sky. People aren’t sure if the mecha is going to come back or not, we may find out in a future live event.
