"You’re just in time Raven, we need all the help we can get!"
— Cold Heart

Cold Heart is an MT pilot, and later Raven appearing in Armored Core 3. He is affiliated with Global Cortex and ranked E-20 in the Arena. He is partnered with Fragile in the Extra Arena and they hold the title of the sixteenth highest ranked team.


Cold Heart was a pilot with considerable combat experience who joined The Raven in facing off against The Controller forces. At the time, he was still an MT pilot, bravely taking on a number of Ball MTs. After a prolonged battle, the two were able to venture further into Ruglen Laboratory, saving Fragile from the Controller AC. He was one of the few Ravens to have ever destroyed a Controller AC. Surviving the battle, Cold Heart then transitioned into becoming a fine AC pilot and assisted The Raven in carrying out a wide variety of missions.


Upon completing the mission Defend Ruglen Laboratory with Cold Heart alive.

Title: Report

"Thanks for your help back at the lab. I can't believe I'm actually a Raven now. So you know, my unit is equipped with shell weapons and would probably fare quite well against opponents that concentrate on warding off energy attacks."


  • Defend Ruglen Laboratory
    • You’re just in time Raven, we need all the help we can get!
    • This area is clear, let’s head in and give the other AC a hand.
    • (If DefeatedAaagghh!

MT The SunEdit

MT Cold Heart

MT The Sun

An inexpensive unit popular despite both mobility and durability problems. Each of these mass-produced MTs is equipped with a rifle and rocket launcher. They are most effective when bunched in small groups.

MT The Sun SpecificationsEdit

Cold Heart pilots a woodland camouflage More MT. Slow to move, and lacking AP, it is only effective when part of a group. Its lack of mobility leads to it being outmatched by faster enemies, and its lack of firepower leads to it being outmatched by heavier enemies.

  • Name: Cold Heart
  • MT Name: The Sun
  • MT Type: Mass-produced Reverse-joint MT
  • Armament/s: Rifle, rocket launcher
  • Armor Points: 2,400
  • Tactical Style: Walk in, stand, shoot.
  • Strengths: Low hiring cost
  • Weaknesses: Confined spaces, mobility, durability, offensive capabilities

AC The SunEdit

AC The Sun

AC The Sun

Much like his old MT, The Sun is a reverse jointed bipedal lightweight model. Its only weapons are the DBZ bazooka arms and the HECTOS large rocket launcher. Although it has excellent mobility with its lightweight frame and devastating power, it is ultimately offset by its rather unfortunately low defense, limited means of attack and low ammunition.



Cold Heart can be hired as a consort; first as an MT pilot and later as an AC pilot in the following missions:

MT The Sun

AC The Sun

In-Game InformationEdit

Formerly an MT pilot working for Crest, his journey to become a Raven has been both long and arduous. He is still getting accustomed to piloting an AC, but his front line experience and instincts are top notch. He is expected to do well.
