The Blue Resistance:

In Sarge’s Heroes 2, Brigitte Bleu claims to be a member of the “The Blue Resistance“, implying that the Blue Nation was under a dictatorship aligned with the Tan regime, prompting an anti-government resistance. This statement would seem to be odd, considering that Brigitte is shocked when Plastro announces his intent to invade the Red Nation, the Orange Nation and the Blue Nation later, though it is more likely that her claims to be a member of the resistance movement was a ruse to gain the Green’s trust.
