Nicknames!

While impressive, the spirits of Spirit Island possess rather unwieldy names.  So the time has come to give them all nicknames!

Here are my proposals.  Some are terrible, some are obscure (or not) references, and some are unimaginative, but here they are:

Lightning's Swift Strike: Sparky
River Surges in Sunlight: Splashy
Vital Strength of the Earth: Rocky 
Shadows Flicker Like Flames: Plato
Ocean's Hungry Grasp: Ed
A Spread of Rampant Green: Audrey II
Bringer of Dreams and Nightmares: Boo
Thunderspeaker: Bang
Serpent Slumbering Beneath the Island: The Bi-Colored-Python-Rock-Snake
Heart of the Wildfire: Bouncy 
Sharp Fangs Behind the Leaves: Mr. Chomps 
Keeper of the Forbidden Wilds: Maro
Volcano Looms on High: Sir Not-Appearing-in-this-Game

That seems just as unwieldy I think I'd just say Rock Snake

Onix?

That one was my favorite, right up there with Audrey II.

even better

Very aptly named!

How about Misi?

Here's mine:

Lightning's Swift Strike: Zapdos
River Surges in Sunlight: Blub Blub
Vital Strength of the Earth: Doorstop
Shadows Flicker Like Flames: Stalker
Ocean's Hungry Grasp: Wipeout
A Spread of Rampant Green: Groot
Bringer of Dreams and Nightmares: Bad Trip
Thunderspeaker: Joan
Serpent Slumbering Beneath the Island: Long Snake
Heart of the Wildfire: Annie
Sharp Fangs Behind the Leaves: Kitty
Keeper of the Forbidden Wilds: Papa Nature
