Eureka (adoptive mother)
Linck is the youngest of Eureka's adopted children. He has a scar on his forehead from when Eureka attacked his family, and was only an infant when it happened. He doesn't remember his real parents at all. He is 3 years old.
He is the cry-baby of the group, but this can only be expected due to his young age. He is very curious and is less aware of the situations around him than Maurice and Maeter. He is often the instigator of the pranks played on Renton by the three children in the beginning of the series, though he later comes around to Renton and begins to accept him once he realizes Renton is always there for Eureka.
Linck, along with his siblings, do not appear in Eureka Seven: AO and it is unknown what became of them.
He and his siblings' names are a reference to the playwright Maurice Maeterlinck.
