  In composite Higgs models with partial compositeness, the small value of the
observed Higgs mass implies the existence of light fermionic resonances, the
top partners, whose quantum numbers are determined by the symmetry (and
symmetry breaking) structure of the theory. Here we study light top partners
with electric charge 8/3, which are predicted, for instance, in some of the
most natural composite Higgs realizations. We recast data from two same sign
lepton searches and from searches for microscopic blackholes into a bound on
its mass, M8/3 > 940 GeV. Furthermore, we compare potential reach of these
searches with a specifically designed search for three same-sign lepton, both
at 8 and 14 TeV. We provide a simplified model, suitable for collider analysis.
