The First suit made, This is his (relatively) simple suit. It works like an Exo-Skeleton. It is a simple Titanium/Steel alloy, that forms together and is able to take hits from small arms fire without injury, it can also take large explosions fairly easy. It does NOT have any force-fields however. It only has its Armour to defend against attacks.

This suit has to manually be put on, It is Pre-Peak Serum. This means it is not good for Peak if he is ambushed, as it takes about a minute to assemble onto him.

The Weapons systems are simple compare the Mark Two. These are...

• Repulsor Beams ( Flight Stabilizers ) - Able to cause a high amount of damage to most things. Causes a high intensity heat + knock-back effect

• Wrist Mounted Missile - Able to blow up a tank with ease.
• Shoulder Mounted Targeting Missiles - Able to track over 10 targets at once and fire a depleted uranium round bullet or explosives.
• 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.
• 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.
• Horizon Implanted - AI into Tony's brain.
• Wrist Bullets - Simple, yet effective. Fires Depleted Uranium Rounds.
• Flight - Able to reach speeds 3x the speed of Sound

The Limitations of this suit is that it is simple, it barely helps him fight against higher tier enemies. It is NOT EMP proof, it can be overridden by too much electricity or hacked. It also has no repairing facilities that can help it repair from major injuries, Only small re-circuiting can be done to avoid a power failure if anything major happens.

The suit is not that durable, It can take a fair amount of heat and cold before malfunctioning, It can easily take small-arms fire and even tank rounds. Blunt force is not very effective against this suit, as it is very durable and the metal on the outside will work regardless of how badly attacked it looks, just the core features like the Arc reactor, Headpiece and main joints need to be intact for the suit to properly function.

A few defenses the suit has are flares, on the bicep area and thighs. To stop missiles.

It can also open up the Abdominal area ( Unique to this suit ) and project a mini-shield of metal string type objects, to tangle up any attacks or incoming missile, It is also Razor sharp, so a Razor sharp net.
