Using her strongest move requires her to reveal her identity freely, thus it deactivates. This actually impacts how she fights, since she can only use her ultimate Noble Phantasm when it's off and while it's on it helps hide her identity in addition to physically covering her face, it serves as a secondary Noble Phantasm that prevents enemy Masters and Servants from easily discovering her skills or abilities.
Fate/Apocrypha: Mordred's Cool Helmet integrates into her armor at will. In the second season he has it further modified with a retractable plate over his mouth so he can eat and drink without removing the mask. Instead of being built for protection, Zero had the helmet designed so he can conceal his identity while still being able to use his Magical Eye, which needs direct eye contact to work (facilitated by a hidden panel on the mask opening with the push of a button). Unusual in that the actual faceplate has to be removed by hand after the rest of the helmet retracts into it. We only know thanks to development material. Although it's a downplayed example, because in the entirety of the show we never actually see it do this, as he's either wearing it or not wearing it but is never shown donning it on or taking it off. Casshern Sins: Casshern has a helmet that retracts into his collar when not in use. And that helmet? Looks like the head of a stylized hellhound, symbolic of Guts's inner beast. Thus, this trope is Awesome, but Impractical, with its impracticality overlooked in fiction thanks to the Rule of Cool. Nor catch your hair in the closing mechanism - or your nose. Also, you wouldn't want to accidentally hit the switch at the wrong time. The multiple moving parts would certainly weaken the helmet and compromise its protectiveness in a fight or a crash - breaking into pieces is exactly what you want a helmet not to do.
Very handy for a Dramatic Unmask.Įven if possible in Real Life, this would probably be a bad idea. The helmets often appear to not need any human interaction, and they usually just fold open with the minimum of fuss. When needed again, it can be summoned back in the blink of the eye.
Through some Applied Phlebotinum, this helmet can usually fold into the armor as if no longer existing. And then they reveal themselves with an unbelievably cool helmet that just slides, clicks, folds and does all manner of other mechanical origami. Picture the scene, the hero (or indeed villain) is wearing their Powered Armor or other such suit. For them, there's a simple solution: the Collapsible Helmet. Heroes or villains who avert Helmets Are Hardly Heroic still rarely want to bother about putting it on, or removing the helmet and carrying it along.
