Gagagigo

The Wiki only gives you one tip on using him, by searching it with Witch of the Black Forest. But he has a more Wiki-worthy use. Use him in a Legendary Ocean deck, and combine with Gravity Bind.

But the main reason I brought up this card into discussion is because of the story behind him. Not a lot of people would care about the tales behind their monsters, but if you want to read a sad tale of lust for power, search Gagagigo and read the Trivia. You'll be surprised just how many cards are involved (including Dimensional Prison).

I like the story too.

This + Giga Gagagigo were an awesome duo I used in my Legendary Ocean beatdown deck I used in those old GX games.

Nothing wrong with having a Level 3 2050 ATK beater and a Level 4 2650 ATK beater xD

They are pretty much my favorite Water Monsters. To the point of thinking how Gagagigo would look like as a spirit who protects his Duelist xD

This card probably has the most interesting tale of all the cards in the game.

Too bad the tale ends in tragedy.
