Ultraman #3- Charge Forth, Science Patrol

Neronga emerges from an ancient well and starts feeding on electricity.  the monster can turn invisible, thus making it far harder for people to believe that it is indeed a monster eating the energy.

eventually the Science Patrol shows up, finds the monster and Ultraman destroys it.

a fairly straightforward episode, with some really cool effects.  Neronga is an interesting monster.  it's a redressed Baragon suit, which I am sure helped with the costs of the show.

back when the show was aired, I am sure it wasn't immediately apparent that it was an older costume, as you couldn't just pop in a disc or tape and compare them.

not my favorite episode, but a decent one.
