This suit incorporates the Peak Serum -

The Peak serum

Stark recently had to inject himself with the Peak Serum techno-organic virus to save his life. The effects are that now the inner layers of the Peak suit can be stored in the hollows of his bones, and he can control the suit with his mind through direct brain impulses. He can also remotely connect to just about any communication device, including satellites and computers, across the world. Stark can even regenerate organs due to the enhancement.

The Peak serum also allows Stark to interface with his armor in a faster and more efficient manner as well, thus dramatically increasing his response time. Without his armor Tony Stark is considered to be above peak human and has displayed superhuman capabilities such as super human reflexes, His speed, strength and agility without his armor is now considered to be at peak human levels.

Because of his unique Peak serum, he is shielded from EMP as he can coat his body in a full metal casing, creating a shielding.

Using the suit this way, he can coat his body in a layer of simple metal that is heat resistant, EMP, Radiation absorbing to an extent and even magnetically not active, so people who control metal cannot move his body. Obviously, this allows him to take punches fairly easily compare the average human as they would be punching metal. But any harder punch will and has hurt him, but the Serum acts like a healing factor, But not an instant healing factor.

This suit gives him many more options than the previous suit.

• Gives him the lifting strength of over 100 Tons, Unlike Mark One of only 50.
• Repulsors : Laser-guided particle beam emission units mounted in the palm of each hand.

• Unibeam: Multi-band light and force beam emitter. Can be adjusted for a variety of effects such as searchlight, heat ray, tractor beam, laser, image inducer and broad-spectrum (UV to Infra-red) light beam.
• Force Shield: A focused photon emitter on the back of his left wrist that shapes into a shield.

• Electromagnetic Pulse: knocks out electrical systems within range, including those of the armor itself, which reboots after 2 minutes.

• Mini gun (shoulder-mounted pop-out): Shoulder-mounted and using an electronic firing system. This is a state-of-the-art Gatling-type machine gun firing case-less ammunition. It can be loaded with a wide array of various bullet types including stun and armor-piercing. Default load out is 1800 rounds of depleted uranium bullets which are fired electrically, minimizing moving parts.

• Micro-Rocket Pack (shoulder-mounted): Similar to an assault helicopter rocket pack, holds a variety of up to 15 rockets, including High Explosive, Concussion, Smoke, Flare, and Miniature Nuclear. Can track upto 15 targets at once, Fires a depleted Uranium Round or other things.

• Gas filters - Can filter out any gas that is intended to harm.
• Foot stabilizers - If a high wind or current attempts to-pick himself up, He can magnetize his feet to the ground, or spikes come out and implant them-self into the floor.
• Short-Range Projections - Able to make a 3D realistic hologram to distract enemies or for other fun uses.
• Flares - Against missiles , Stored in his arms, and legs.
• Self Destruct - As a last resort, if activated the core in the suit will create a nuclear blast
• Flight, Able to now reach 10 times the speed of sound

• Magnetic Force-Field - The suit creates a force-field which can be modified at will by its user by incrementing the power of the Reactor. It can be so powerful to destroy bullets or repel people.
• Psi-Shields - The suit has a built in Anti-Illusion/Mind Infiltration facilities, This works by creating a complex series of "fake" brains that can trick foes who are trying to infiltrate his mind. This further helps with Horizon, Being an AI can temporarily control his mind, or tell him if somebody is attempting to make an illusion, or even control the suit while it sedates tony to prevent a disaster.

• Override: When required, This new Suit can amplify, including strength amplification, durability amplification, and repulsor intensity can be greatly increased, by bypassing safety circuits and limiters. However, there is a chance that this can result in a complete system failure of the armor. The range of the Override can be controlled as only reaching his very limit and staying at it for a long time will cause a system failure.

• Defensive modes: Camouflage mode allowed Peak to blend into his surroundings while a stealth mode rendered him invisible to others’ sensors.
