The signals of the neutral top-pion \ensuremathπt0 at the first muon collider (FMC) are discussed by calculating its contributions to the processes \ensuremathμ+\ensuremathμ^\ensuremath-\ensuremath→bb and \ensuremathμ+\ensuremathμ^\ensuremath-\ensuremath→tc. We find that the contributions to the process \ensuremathμ+\ensuremathμ^\ensuremath-\ensuremath→bb are very small and the ratio of the signal over the square root of the background (S/√(B)) is smaller than 0.2. However, in most of the parameter space, the \ensuremathπt0 can generate 36 and up to 649 observable tc events at the FMC. The signals of the neutral top-pion \ensuremathπt0 may be detected via the process \ensuremathμ+\ensuremathμ^\ensuremath-\ensuremath→tc at the FMC.
