A very large and near impregnible suit of aurmor worn by space marines (warhammer 40k universe). This suit has a thermo nuclear power pack whitch gives it its name, Power Suit. more simply its like a midevil suit of armour but it has hydrolic and phumatic joints, nero interface, built in Vox communicator, ect. Also this suit is made of a imaginary super metal called Adimantium whitch is like a super titanium/iron substance.
