Chameleos

Flying, Infect, Infect Boost (instead of 1 -1/-1 counter put 2 on a creature)
{4}{t}: Gain control of target non-creature permanent.
{5}{b/g}: Chameleos gains Hexproof and can't be blocked until end of turn.

Chameleos has the ability to camouflage itself by using the electric currents running through its skin, refracting light in the mist and thus making its body invisible.
