Glint and Spark are twin Pokémon.

Although they are technically different species of Pokémon, Plusles and Minuns are so closely related in nature that even if the twins didn't share a single mother, they would very nearly be related anyway. They have lived together since birth, raised in one of the various Pokémon Daycare Centres turned Orphanage, never knowing their true parents.

Throughout their lives they developed a close, intimate relationship with one another. It's thought that spending every moment together as well as their rapidly developing bodies are said to be the cause of this physical relationship between siblings. However, when their relationship is stressed, it is revealed that their connection falls deeper - they are very much in love, and have been for most of their lives.

They were adopted by Nori (Norithics), a raccoon (featured center of the picture) at the age of sixteen, and moved from the Pokémon Daycare Centre to live in his beach-front home in a city where few Pokémon live. Their relationship with Nori began rocky at best due to their general mistrust of adults, but when it became apparent that Nori wasn't going to give them up, they became much more fond of him.

They now attend high school in the city. As of yet, Nori is unaware of their relationship.
