Knecapeon "Kneecaps" Mace (Light Mobius)

Knecapeon Mace (MxYL) is the Mobius: X Years Later universe counterpart of Knecapeon "Kneecaps" Mace the Echidna.

25 Years Later (Unaltered)
In the unaltered timeline, Mace attended Lara-Su's Unveiling and was surprised to see Knuckles out on the dance floor with her. He also became somewhat embarrased when Julie-Su asked if he was with Demi-Na, who he considered nothing more than a friend.

25 Years Later (Altered)
Mace was one of the few who were not erased due to King Sonic's use of the Tachyon Displacement Chamber.

Five Years Later...
Five Years after Shadow's defeat, Mace worked with members of the Chaotix. He was sent on a mission to Mazuri with Vector by his brother, and as such, did not know of the events that had unfolded at the celebration of the Five Years of Peace.

Romance
Although this isn't confirmed, it was believed by Julie-Su that Mace had something going on with Demi-Na, but denied it, possibly to hide the truth.
