The Mark 45 (Mark XLV) is the forty-fifth Iron Man Armor, as well as one of the many new built suits created by Tony Stark. It is the first armor to feature the new female Artificial Intelligence / A.I. Friday, who was integrated into the armor before the Battle of Sokovia.
It is featured in Avengers: Age of Ultron, along with the Iron Legion Armor Drones, the Mark 43, and the Mark 44. The Mark 45 is also the first armor to feature a hexagonal outline design for it’s Chest Repulsor Transmitter (RT).
The Mark 45 has a unique design, one different than any of its predecessors: the hexagonal-shaped indent around the circular Chest RT. The paint scheme is more red than gold. The helmet design is similar to the MK 43 but is more compact and has larger indentations at the top. This armor also is completely composed of vibranium.
The armor greatly amplifies the user’s base strength and combat skills to extremely massive levels. It is based on the Mark 44 energy- strength technology, and may be stronger and more durable than the Mark 44. It can also lift up most objects with ease such as large vehicles, aircraft, buildings and more. It is shown to be able to lift a huge S.H.I.E.L.D. Transporter which weighs at 200 tons, even that was carrying around 30 passengers.
The armor is extremely durable, capable of withstanding blasts and extremely powerful strikes, as well as completely bullet-proof. The armor also has an upgraded energy shield that passively improves its durability of the user. Nearly at the end of Battle of Sokovia, when he blew up the flying city together with Thor, Tony was able to withstand the extreme explosion of it and recover instantly with minimal to no damage.
As with all new-generation Iron Man Armors, the Mark 45 is capable of enhanced flight via its repulsors and flight stabilizers, making it one of the most stable and fastest armors to date. The armor can fly past the Earth’s Atmosphere because the armor uses energy more efficiently than its predecessors.
