The Toa Kuelu of earth having completely mastered his abilities. Since he's the head Toa I'm more interested in perfecting him, just bear with me.
About this creation
Tohuka, when he first became a Toa Kuelu (A toa with access to their natural element + light), had not complete mastered his abilities yet, powerful though he may have been. The only way for him, as well as the other Toa Kuelu, to master the Kuelu abilities would be for Kihoku, himself to materialize and teach them, but instead, he sent Komorro back from the dead with a set of completely mastered abilities (see Komorro: Toa Kuelu of Stone) to teach to the others.
Under Komorro's instruction, Tohuka infused his original sword with the Chaos Blade, creating a sword that is neither good nor evil, but neutral and with great power. It took him a long time (six months pass between the Search for Komorro and the Leviathan Epics), but he has finally mastered his power. Other improvements include a faster lightform, enhanced regenerative abilites, and better attunement to life-force.
"The Toa Kuelu are Mata-Nui's chosen, to wield his power alongside our own. It is of the highest honor."
To Metru-Nui ambassadors: "I am the leader of these Toa and the second in command to Turaga Gurunu. What business have you?"
"Mastering the teachings of the Kuelu art opens the mind to many truths, like not eating beans before going on a date."
To a Krita Ghost Squad. "Take one more step and the earth'll swallow all four of you... Per my order."
Close up, actually with less armor but greater mobility.
The new sword (blade inspired from Ziazeran's Anozoun). Abilities listed below.
The new leg style.
The new arm style. I'm still perfecting the arm armor, but I'm trying to get away from just slapping an Inika piece on and calling it complete.
Coming at you!
His list of abilities:
Outstanding Nightvision (natural Earth-Toa ability enhanced with light power)
Cause Earthquakes of varying magnitude
Infuse light with earth
Create sentient earth beings (number depends on how focused he is)
Create earth giants (with armor if combined with Komorro's abilities
Command of the earth (use your imagination on what he can do with this one. If you can imagine it, he can probably do it)
Lightform (can move/attack at the speed of light, think Umbra)
Create and fire pure light
Uses light to regenerate wounds and repair broken armor/weapons/etc.
Can unleash a nova blast of either earth, light, or a combination of both.
A list of his sword's abilities:
Use absorbed energy to increase durability of tools/armor, heal, or increase attack power.
Absorb and expel wrath energy (See Tohuka: Demi-Toa of Wrath)
Channel light/earth elemental power
Perform melee strikes in lightform (takes on light form with Tohuka)
Fire burst of neutral energy (combo of light and dark. Insanely powerful, but draining. This can heavily damage beings as powerful as BoM members)
A list of his shield's abilities:
Can send the kinetic energy used against it back it it's opponent (if an enemy strikes the sheild, he would be thrown back with equal force)
Vines can extend and entangle enemies (possible use for absorbed power)
Can fly with entangled enemies up into the air and drive them into the ground (this was one of the original powers, planned to make an appearance in the 2006 epics, but it never happened).
Can become a sentient insect-like being if fed enough absorbed energy, aiding Tohuka as an independent soldier (This was the prized ability of the ancient Beetle-Jaw shields. See Tohuka: Demi-Toa of Wrath). Will return to shield form once energy is used up.
