E.L.E.C.T.R.O.N.

The E.L.E.C.T.R.O.N., or Electrically-Lit Extremely Catastrophic Teravolt-Running Overcharged blooN, is a non-MOAB-class bloon with an acronym. It takes only 5 hits to pop, but moves twice as fast as a pink bloon. It pops into S.T.R.I.N.G., giving it a (surprising) RBE of 155. It also has one attack:

Its one attack is called Electrical Discharge. Electrical Discharge involves the bloon sending out teravolts of electricity, singing all towers in a short radius, and temporarily overloading machinery. It takes 15 seconds to charge this, though, so it won't be an issue later on.
