H2Overse

The H2Overse is one of the neighboring universes to the Power Rangers multiverse. It is focused on Australia, specifically a set of girls who become mermaids (with human forms while dry, and water-based superpowers) through a combination of lunar magic and a few particular pools.

It is vaguely possible that this universe's Earth actually has two satellites, given that one observed lunar eclipse showed a dark body passing in front of the moon instead of the Earth's shadow.

Parallels

 * In both universes, recurring characters tend to disappear offscreen, their departure explained by only a line of dialogue, if at all.
 * The world appears to exist as a show in Universe Gamma, as Garfield's mother used to be a big fan.
