With A Force Field Projector

Doctor Doom’s armour is pretty durable to begin with and the fact that it can project a surrounding force-field makes it even more so – but it also has a miniaturised force-field projector that can envelope targets in a debilitating force-field of their own.

The villain has used it on a variety of opponents – including opponents as physically powerful as the Hulk – and it’s always been a very effective method of thwarting them.

The Hulk typically and crudely described it as “something invisible holding Hulk back” but, just like Doom responded, it was actually a very apt description of the situation. When Hulk is physically unable to escape from something, you know it must be pretty powerful.
