Mon Machine

Using friendship to gain help from a Mon.

A Sub-Trope of Mon series and stories, a Mon Machine is a magical or technological device that can interact with a Mon in a variety of different ways. Most frequently this is establishing the initial bond between the Mon and its owner/user. However, a Mon Machine can instead provide support or enhancement for an already-bonded creature. In rare cases, they can give their user one or more superpower(s) instead of the Mon -- and in these cases, this can result in All Your Powers Combined or even a Yin-Yang Bomb.

Unsurprisingly, Mon Machines are usually Toyetic and make for excellent merch, especially since they will almost always be mandatory cosplay props.

Not to be confused with an ungrammatical Parisian's claim to own a device.

Examples of Mon Machine include:
