I have the sudden urge to introduce this.

About the size of a standard I Phone
It's Biometal Model X. It's from Mega Man ZX, it is one of the few Biometals. This one was created based off of X and was made by Ciel, a main character in the Zero series. (It's assumed the biometals [Except Model W] were made by Ciel, that or a ancestor of Ciel.) The Biometal Model X has a personality of it's own and can be wielded by anyone. It's sort of used like a digivice from the Digimon series. Allowing the user to transform. When transformed they get a arm cannon similar to X's X-Buster, as well as the strengths and such of a Reploid (but not X's limitless potential.)
Abilities are:
Standard dash, much like X's. Allows the user to perform a instant burst of speed. The dash is 2x faster than that of running speed. Though it can only be used in bursts.
Model X-Buster. A arm cannon similar to X's X-Buster. Can fire normal shots, and charge up for a single large blue blast. Can be charged to a 3rd level to fire two charge shots at once.
Increased strength, and speed.
This is the outfit the user gets when transformed AKA Megamerged:

Though the size and shape of the outfit matches the wielder of Model X. Only people that can use it:
Anyone that is not a Reploid or machine can use Model X. Meaning Zero, Gate, X, Axl, Alia, and Phantom can't use Model X. Almost anyone in this RP can use it.
Model X has an A.I. and can float in midair when not in use. It's personality is much like X's, but far more mature. It can also project a small barrier to protect someone when not being used.
Currently it is floating around Hawaii in search for a new wielder.
