J.A.R.V.I.S.

J.A.R.V.I.S. is Tony Stark's artificial intelligence system. He can summon suits for Tony at will, namely, the Iron Men. He is automatically uploaded into the Iron Man suits (excluding the Mark I). The Mark XLII (42) comes to Stark in pieces (chest, helmet, arms, legs, hands, boots). So does Armor Model 29.
