This merge offered Seth superhuman strength and armour against various attacks plus a powerful roar that shook his surroundings, but this caused him to get easily angered.
She is the only current Defender to have witnessed first hand the final battle between the Ethos and the Wizards of Yan, as she had gone back in time with a staff that Kor Yin-an gave to her.
At the time, Nazmul was his human self, the Order of Infinis was not formed and their key members were allied with the Wizards, and the Armies of Yin were warriors that fought for RaDos.
The boots are both an asset and liability to Kara, since they allow her to jump great heights and give her greater balance, but are vulnerable to various types of electronic interference.
It was also shown in Absolution that Rion seemed to care the most about Kara after her sacrifice (apart from Erik) and even went to great lengths as to transforming into his dark half and attacking Adam, for not trying to protect her.
He also built Seth's robotic arm, when his hand was destroyed by Brackus, and the boots for Kara as recompense for not being able to stop the accident that paralyzed her.
But like the previous person before Erik that tried to seal this creature using Mal-ra and Orn-ra, Kara sacrificed her physical body, and her spirit lives inside the Life Stone.
One example was when Brackus tried to trick the Defenders ("Perfect Host") by giving the Yin-tos a big pep talk, mentioning they wouldn't make it there for two days.
His wizard spells involve dispelling energy from Di-Gata Stones and firing green beams of light to grab objects and to attack enemies.
Flinch specializes in the Yin and Infinis sigils, and his attacks generally involve terrorizing his enemies with spirits, ghosts, and grotesque monsters.
His contempt of his peers eventually led to the rift that saw him change sides and join Nazmul's growing army as a blind follower of the Order.
Malco specializes in Yin and Dako sigils, and his spells are all about powerful attacks which range from dark flames to meteors to a swarm of locusts.
He managed to help the Defenders by attaching an override device to their vehicle, causing it to spin out of control and send it and Malco flying.
He ends up surviving the fall, but he becomes frozen solid on Mount Froza, being guarded by two Sigil Slayer creatures with their egg pile.
Erik returns in the village in "Mel on my Mind" and is greeted by an enthusiastic Joshu, who is more than happy to give him the dakocite he needs for his stone carving.
Joshu arrives during the battle between Seth and K'Tash, and the latter knocks the vial out of his hand, releasing the Dakocite dust and curing Mel, Rion, and Brackus.
At the end of the second season, Rion uses the ancient guardian language to communicate with Si'i, who attacks the last Ethos but is turned back to his human form.
While the Zad and Ethos creatures attacked the temple, Tzur creates a portal to allow the Defenders to escape to the Yin-Tos Ridge.
Before the Defenders escaped, Rion was traumatized by the loss and eventually revealed his dark incarnation power to kill one of the Zad and cause the others to retreat in fear.
If he had done it in time, he would have administered the antidote, which was later a trick to let Kara die, use Seth to regain his own position in the Order, and eliminated an enemy to Nazmul.
However, it was all in vain as Seth escaped from Brackus's Keep and got Kara to the forest where the Viridian Spiders lived, as the milk of these creatures was the antidote to the Saviped poison.
Doku then took control of the tower and eliminated the cult and attempted to take the final Icon, but was defeated and left to die on Rados Prime.
Kid Cole is a bandit who tried to frame the Defenders for his crimes in "The Town that Time Forgot", as he was raiding caravans for their supplies and selling them to the villages for a price.
As punishment, the wizards put Kor in a state of permanent undeath, the Arkham Mal Rash turning him into a lich, and to be chained as penance.
Kor, being undead, survives the assassination attempt, and upon reviving he attacks Malco and Lady K'Tahsh and steals the Sacred Icons.
In Di-Gata Dawn they join forces with the defenders during the Ethos war after Erik admits that humanity did invade their planet, and shows them the two lost signals as peace offerings.
Most Zad warriors are armed with whips that contain paralysis effects, have high agility and are the only beings that use Ethos with other sigils (most commonly with Dako).
Their only known spell fires a device similar to the Power of the Guild, except explodes into a highly viscous liquid, that pulls targets under it like quicksand.
But because of the damage it caused to RaDos each time the Spell of Binding was cast, it shattered a large portion of the realm and sacrificed the Defender's parents.
The creature may be a guardian, possibly left by a Gadashin Monk who hid the Pure Stone in the temple to guard the place from intruders.
