Idiosyncratic Mecha Storage

It's not a very bright idea to park your Humongous Mecha standing straight up. It's a pain to climb back up to the cockpit, it can get knocked over easily, plus it just looks a bit silly.

So, make it kneel or curl up into a ball. With the center of gravity lowered, the mecha is harder to knock over. With the height lowered, the mecha is easier to store and can't get in trouble for impeding overhead air traffic. The pilot has a shorter and (usually) easier climb back up to the cockpit. Unfortunately, parking the mecha like that makes it a larger target for dive-bombing birds.

See also Sleep-Mode Size, for when there's less mecha and more sleepies; and Retractable Weapon.


Examples:

Anime & Manga
  • Inverted in Neon Genesis Evangelion, where standing up is the idle position for an Evangelion. It's justified in that it's stored in a huge cage, and the entry plug is inserted into the back via cranes.
  • In expanded Gundam works, because they generally operate in 0-G, the Zeon space colonists do not store their mobile suits standing upright on racks like their Earth-based Federation rivals and instead have them lying down, back-to-back, or strewn about all over the hanger because there is less of a concept of "up" without gravity.

Film
  • Star Wars Battle Droids are designed to be able to fold into a compact shape, with the legs folded and pulled up to the chest. This allows for convenient transport and storage.

Video Games
  • The Boxguards of Deus Ex: Human Revolution are called such because they fold up into a cube when inactive. One memorable room has hundreds of the things on the walls, stacked together in compact form.
  • Vital Suits in Lost Planet have a specific "folded-up" mode, so the pilot can climb in and out easily.
  • The powered armour units in FEAR 2 crouch and open their cockpit when they're usable so the pilot can climb in, or stand up straight with a shield activated when they're in an automatic repair mode (which tends to be how you find unoccupied ones to hijack).
  • Starcraft II: Thors have a unique animation that plays when they get picked up by a dropship. They fold up into a more compact block hanging under the ship.
  • Plenty of mechs in Mass Effect series, such as geth armatures, LOKIs or YMIRs, assume a compact shape when not activated, making for easier transport.
  • One of the activation animations of the MECs in XCOM 2 has them rising from a ball and powering up. Can look silly depending on what the MEC did right before the animation.
