This card is based on hydrogen. Hydrogen is a gas, that together with oxygen creates water.
This card's effect is probably from the fact that it is based on hydrogen, as hydrogen is the most common element in the universe.
This card resembles an Ankylosaurus.
This card is a Dinosaur-Type, accented by its name ending in -don, which is the ending for many dinosaur names (e.g. Iguanadon).
The -don suffix is Latin and means tooth. This makes relatively little sense in the context of this card, but the card namers probably just chose it because it is associated with Dinosaurs.
The DEF of 1000 may be a reference to the Atomic Number of Hydrogen, which is 1.

Bonding - H2O: Tributing 2 "Hydrogeddon" and 1 "Oxygeddon" is a cost to activate "Bonding - H2O". You can Tribute face-down monsters for this cost.
Water Dragon: When this card on the field is destroyed and sent to the Graveyard, its Optional Trigger Effect activates. You must have at least 2 "Hydrogeddon" and 1 "Oxygeddon" in your Graveyard to target, otherwise the effect will not activate. If you have 3 correct targets, the opponent can chain "Disappear" to remove from play 1 of the monsters, but the other 2 will still be Special Summoned.
Water Dragon: The effect of "Water Dragon" that activates when it is destroyed targets 2 "Hydrogeddon" and 1 "Oxygeddon" in the Graveyard.
