The S.H.I.E.L.D is a defensive combat blimp developed sometime between the fifth and sixth war. It was mainly designed as a moving, weaponized barrier. Not many exist due to the material needed to create the mighty outer skin of this blimp, so the Bloon Army dispenses them sparingly. Equipped with a solar-powered force shield generator, these blimps can only appear in maps that are during Day or Lights On.
