  We explore the possibility that Dark Matter is the lightest hadron made of
two stable color octet Dirac fermions ${\cal Q}$. The cosmological DM abundance
is reproduced for $M_{\cal Q}\approx 12.5$ TeV, compatibly with direct searches
(the Rayleigh cross section, suppressed by $1/M_{\cal Q}^6$, is close to
present bounds), indirect searches (enhanced by ${\cal Q}{\cal Q}+\bar{\cal
Q}\bar{\cal Q}\to {\cal Q}\bar{\cal Q}+{\cal Q}\bar{\cal Q}$ recombination),
and with collider searches (where ${\cal Q}$ manifests as tracks, pair produced
via QCD). Hybrid hadrons, made of $\cal Q$ and of SM quarks and gluons, have
large QCD cross sections, and do not reach underground detectors. Their
cosmological abundance is $10^5$ times smaller than DM, such that their unusual
signals seem compatible with bounds. Those in the Earth and stars sank to their
centers; the Earth crust and meteorites later accumulate a secondary abundance,
although their present abundance depends on nuclear and geological properties
that we cannot compute from first principles.
