Toughest Battle Armor ?

Dooms and it isn't close, the only other answer could be "other" and that could mean anything.

Scarab.

The destroyer armor

Kang´s armor

Lex or, Bleeding Edge.

Ares' armor easily. Indestructible.

Master chiefs armor.

Out of that list, Lex.

Out of all, probably the Destroyer armour.

Unless the Infinity Gauntlet counts as a piece of armour.

@sheenlantern: Out of all, probably the Destroyer armour.

It could be argued that the Entropy Aegis is easily in this category, but I see your point.

The real question is. What is the n7, spartan, and crysis suit even doing here?

Anyway, the most powerful? Idk.

The one I'd personally love to have? Lex's suit. As long as it came with a helmet so I couldn't be headshotted.

Destoryer armour with a shout out to Hercules's Nemean Lion Skin.

Destroyer armor, next comes DC ares armor, next comes Dr Dooms armor in durability, and Iron mans extremis in weaponry.

Bleeding edge armor easily. that armor can tank almost anything from conventional weapons.

Where's Ultron? It's probably a tie between Ultron and the Destroyer.

Think about it. There are four characters in the Marvel Universe that are truly physically invulnerable: Destroyer, Ultron, Mangog, and Juggernaut. A fight between any of these four would end up as a stalemate.

It actually has an invisible force shield so your good there. All the protection, none of the vision impairment.

Adamantine Armor

The Destroyer armor easily

IIRC it was created to go up against The Celestials of all beings!

I am not limiting the battle armors to comics only and perhaps I should have said that the battle armor had to be wearable since it is armor and the Destroyer and Ultron are not and they are already have some form of consciousness.

Destroyer Armor by a mile... But since its not here, im going to side with the alien... Scarab Armor ftw.
