Hmm I definitely would like to see sub-divisions to respective elements (example: Earth can control sand, stone, Magma, Iron etc.)
I would like to keep Ice and Water separate because their natures are very different and I think that was reflected well through their characters. With that said though they COULD be lumped together and for (the sake of consistency with this it’d be better if done)
Fire could maybe could use Plasma as a sub-ability
Air I don’t know
I WOULD like to see Lightning as it’s own element because that’d be neat but…I can’t see his character being anything other than a mix of Tahu and Lewa.
Gravity would be cool but that’d be kind of OP
Psionics and Sonics don’t really fit in for an elemental team I think they’d be cool Side characters IMHO.
So I’d rather see Jungle/Plantlife and maybe make him the stealth guy.
The way I see It each Toa serves a purpose
Fire- (the Fighter/Warrior/Leader) ; Weakness: Pride, Stubborn, Rash
Water: (the Perceptive one/Peacemaker) ; Weakness: Inability to be aggressive except when provoked
Air: (Witty one, Adaptive and Playful); Weakness: Sometimes drops his/her guard
Earth: (The Muscle) Tough, Unmoving, Wise ; Weakness: Takes things head on
Jungle: (the Stealthy one) ; Weakness: Wanders off <<basically this is Kopaka 2.0
so for the 6th Toa the only ones that would be left would be Sonics, Lightning and Gravity (or Light/Shadow)
So if I had to pick I’d choose Lightning (maybe as like the youngest in the group but someone who shows potential and could shape up to be the next leader)
