Poor Gill Grunt is the only starter pack Skylander to not have an alter-ego *In-game variant*, he is crying because of this, but I do hope that he may get one in the 4th Skylanders game.

The Starter Pack Skylanders have alter-egos but Gill.

Spyro: Dark and Legendary
Cynder: Skeletal*
Trigger Happy: Legendary and Springtime
~Pop Fizz: Punch and Hoppity*
Jet-Vac: Legendary
Ignitor: Legendary
Stealth Elf: Legendary and Dark
~Eruptor: Volcanic
Double Trouble: Royal
~Slobber Tooth: Dark
Tree Rex: Gnarly
Wash Buckler: Dark and Holiday*
Blast Zone: Dark
Rattle Shake: Quickdraw
Free Ranger: Legendary

~ Regular Pop Fizz, Eruptor and Slobber Tooth are not available in starter packs, but their certain alter-egos do.

* Cynder, Pop Fizz, and Wash Buckler have Lost Islands alter-egos that are not available as interaction figures.
