Tsukumogami

Tsukumogami are beings from Japan that are created (not born) when an inanimate object reaches the 100th anniversary of existence (its "birthday", if you will), and gains a spirit, personality, etc.

Appearance
Tsukumogami tend to look humanoid, however, they do still have elements of their inanimate form (e.g. a clock tsukumogami having clock numbers on their face, a telephone tsukumogami having the reciever and transmitter in each hand, a bell tsukumogami having a bell-like lower body, etc). However, all tsukumogami have one thing, appearance-wise, in common, and that is the Japanese kanji symbol for tsukumogami (付喪神 ) etched somewhere on their body.

Behavior
Tsukumogami behavior depends on how they were treated in their past, inanimate "life". If their owner(s) treated them with respect, love, etc., then they will return said love, respect, etc., to their owners and others. Contrariwise, if one neglects or abuses them, then they will abuse others in return.

Powers
Most tsukumogami powers depend on what they were in their past, however, there are a few powers in common,
 * Enhanced durability: Tsukumogami are able to withstand numerous blows of internal and external assaults.
 * Enhanced endurance: Tsukumogami are able to survive with little to no energy for an extended amount of time.
 * Form switching: Tsukumogami are able to switch between their humanoid form and their object form at will.
