Knecapeon "Kneecaps" Mace

Knecapeon, going by the nickname Kneecaps is the son of Lara-Le and Wynmacher, and the half-brother of Knuckles. Knuckles is rather put off by his new baby brother, for several reasons: his horrible name (Knuckles and Kneecaps?) and habit of hitting Knuckles on the head with his rattle. Kneecaps is a rather stereotypical infant: he loves his rattle - and hitting Knuckles with it - speaks in baby gibberish that most people do not understand, and is inseparable from his mother. Despite his tendency to hit Knuckles with his rattle, he seems genuinely fond of his older sibling. However, this fondness would have been noticeably decreased had Kneecaps been able to understand that Enerjak, whom he encountered some time later, was his transformed older sibling.

In Mobius: 25 Years Later, he is understandably more mature, about 25 at the time of the story. He also goes by the more mature (and perhaps more apt, considering his behavior as a child) name Mace.
