The Mark 41 (XLI), also known by it's name as "Bones", is a Skeleton Suit and was one of the many newly built suits created by Tony Stark, sometime after the events of The Avengers.

It was featured in the movie Iron Man 3, and made it's debut in the movie when Tony ordered J.A.R.V.I.S. to initiate the "House Party Protocol"', in which it was activated along with all the other suits to aid Tony in his battle against Aldrich Killian.

The suit earned it's name "Bones", because of it's external appearance which has a thin plating with the internal contents of the suit being exposed. The suit specializes in speed and maneuverability and is lighter than the usual Iron Man armor.

Armor DesignEdit

The Mark 41 has black and silver plates which cover the internal systems of the armor as well as serve as the strong thin layer of armor itself to protect the user operating within the suit. In it's overall design it has thin golden lining and also has gold plates across it's streamlined body armor.

These designs are used to increase it's maneuverability, which gives it the appearance of a skeleton, hence the name of the suit's type.

Armor CapabilitiesEdit

Armor SeparationEdit

The Mark 41 has the special and unique ability to separate its armor pieces and fly separately.


With the Mark 41's lightweight structure, its speed has increased greatly compared to other Iron Man armors. Having been built to be more maneuverable and faster in speed, the Mark 41 can easily dodge obstacles or projectiles thrown at it.

Its speed may not match that of the Mark 40's, but it can swiftly fly around without any difficulty. Because of its light structure, the Mark 41 is the most versatile of Tony's armors.


The Mark 41's structure gives it several unique abilities. For example, The suit has very smooth joints, which makes movement very easy. Aside from this, the armor itself lacks the regular plating on an Iron Man armor, which would increase the weight and bulk of the suit.

Combining all these factors, the Mark 41 is a very flexible armor and movement made by the user would be very swift and easily done. The armor's flexibility allows it to dodge obstacles easily, as well as projectiles that are thrown at it.   

Armor FeaturesEdit

Armor Add-OnsEdit


The Mark 41's armor piece interlocking ability.

Built as an exoskeleton suit of an Iron Man Armor, the Mark 41 has little plating covering it's entire structure, which makes it's defense level weak and vulnerable to powerful attacks. Although plateless, the Mark 41 has a special mechanism that allows other armor parts to attach to the uncovered areas of the armor.

The suit allows any usable Iron Man armor plates to be able to attach to the armor and interlock with the suit, which makes it possible to have armor to cover its internal systems.



The Mark 41 has standard Repulsors.


The Unibeam of the Mark 41 is circular in shape and its outer covering is plated with thick golden lining. The suit has twice the power output as the Mark VII's Unibeam due to its new and improved Vibranium Arc Reactor Mark II, which it uses just like the other suits.


Before Iron Man 3Edit

It was presumed to be created just a few days before the Mark 42 was in the initial events of the movie, Iron Man 3.

Iron Man 3Edit

The Mark 41 was activated by J.A.R.V.I.S. along with all the other armors in the Hall of Armors under the "House Party Protocol". It then flew out of the Hall of Armors and went towards the Roxxon Oil Rig, together with the other 35 armors.

When Tony gives J.A.R.V.I.S. the order to "Target all Extremis heat signatures. Disable with extreme prejudice." J.A.R.V.I.S. replies with "Yes sir!" which echoes throughout all the armors, including the Mark 41.

The armor then begin targeting and attacking the Extremis Soldiers in the area, fighting them off in the ensuing battle.

The armour is later seen hovering in front of five Extremis soldiers. Jarvis, who was controlling the armour, remarks, "Gentlemen," as the armour then splits apart. The corresponding pieces fly into the Extremis soldiers and knock them off the platform, presumably killing all five of them. The armour pieces then reassemble.. The suit doesn't make an on screen appearance for the rest of the movie.

It is unknown what happens to the Mark 41, as it may have been destroyed in battle by the Extremis Soldiers, or blown up by Tony's order of the "Clean Slate Protocol", as a sign of his devotion to his girlfriend, Pepper Potts.
