Be A Mon is a Mon sub-trope where a character is transformed into a tameable monster. This transformation can happen with the help of a Mon Machine. It may even be done by fusing a person with their Mon. There are different applications when fusion is involved, such as a Monster Upgrade or creating a Mon-Human hybrid.
