Locke is a strong parent who cares about his son, but firmly believes that his affiliation with the Brotherhood and Knuckles' duty matters more than his family, or even the possibilty of his son's happiness. This has led him to clash on more than one occasion with Knuckles, and Locke has also had choice words with his ex-wife. She has since found another husband, and with him is raising a new family that Knuckles is considered a part of, while Locke isn't. Locke's single-mindedness and secrecy make any relationships difficult.
Knecapeon Mace, affectionately known as "Kneecaps the Echidna", is the son of Lara-Le and Wynmacher and half-brother to Knuckles the Echidna. A rather energetic infant, he is extremely attached to his parents and fond of his brother Knuckles, whom he enjoys hitting on the head with a rattle. He was born some time during Knuckles' powerless year in Knothole, his conception having been revealed to Knuckles some time before his temporary death. Kneecaps remained with his parents as they stayed with the Dark Legion as the Angel Island resistance to Doctor Eggman's regime, then in the village built by the survivors of Echidnaopolis, followed by his transportation to the ruins of Albion, which were then rebuilt to serve as a new homeland for the Echidna race (excluding those members of the Dark Legion who were appalled at the loss of their cybernetic implants.)
