Tiso

Tiso He is arrogant, thinking of himself as the ultimate warrior and showing nothing but contempt for the weak.[4] He almost pays no notice to the Knight until later on, and even then he finds them beneath him.[5] The only piece of clothing, relatively speaking, is his hood and shoulder pads, undoubtedly a very bad armor, however, he is someone who has shown strength in combat...I wish he had it in intelligence His shield serves as a kind of frisby/boomerang, since he can grab it back, the shield has sharp blades which are activated when thrown or when he is on guard

Despite his bravado, he is never actually fought, as he dies off-screen in the Colosseum of Fools, his body later found dumped by the acid pits at the bottom of Kingdom's Edge with the other slain warriors.

Tiso has an elongated blue hood shaped like a drop, his face is covered by the hood, he has a breastplate and thin legs. Tiso is an adventurer who seeks the Colosseum of Fools for the sake of a challenge. He fights using his shield, which he claims conceals a “deadly surprise.” His true face looks almost the same as when he wears the hood, except that it turns out to be an ant, and he has only two pairs of antennae. His face is black with white eyes. The central armor of his torso is bluish, it is more like an inseparable exoskeleton than armor, his extremities such as head, arms and legs are completely black. Like other insects, it does not have a nose, ears or hair (because as they are insects this does not exist among them). He always hides his face under his hood, not because it bothers him, he just doesn't care whether he shows his face or not, he is one of the few insects that don't wear a mask, Maybe that's why he wears his hood. He wears no pants or clothing other than his "armor,"

-Hollownest (the kingdom in general) The Radiance was essentially an old god, referred to as the Old Light, who created the moth tribe and potentially all of bugkind. However, under the Radiance, bugs were something of a hivemind, reduced to their base instincts. It seems to consider the Void its ancient enemy and has the power to manifest in the dreams of bugs.

Then came the Wyrm, another ancient being, who died at the Kingdom's Edge and reincarnated as the Pale King. He built Hollownest and became a new beacon of light, supplanting the Radiance and expanding the minds of all bugs under his influence. To rule as the only god, he tried to get rid of the Radiance, but it could not simply be forgotten.

So the Pale King drew upon the powers of the Void, experimenting to create a perfect hollow vessel to seal the Radiance away. After a long and arduous process, he created the Hollow Knight, who he deemed the perfect vessel, and convinced three powerful bugs to become Dreamers and act as a seal. So now the Radiance was contained within the Hollow Knight, whow as further imprisoned in the Black Egg and sealed by the power of the Dreamers.

Still, the Radiance managed to leak out over time. It appeared to bugs in their dreams, and its presence manifested as the orange infection that you can see everywhere around Hallownest, robbing bugs of their expanded minds and reducing them to husks. Now it's the job of your character, another vessel who was presumably deemed a failure, to take up the mantle of Hollow Knight and replace him as a vessel to seal the Radiance, but first the failing seals have to be undone by destroying the Dreamers, and the old Hollow Knight slain.

Under the guidance of Hornet, who is also a creature of the Void, but somehow different, you find another path. You go first to the cast-off shell of the Wyrm to obtain his power of kingship and use it to open the door to the Abyss where you were created. There, you face your past as a creature of the Void, and with the power of the Kingsoul, manage to unite this dark chaos under your command. Finally, with the Void at your beck and call, the aid of Hornet and the awoken Dream Nail, you can not only contain the Radiance, but enter the dream of the Hollow Knight to face the Radiance itself and consume it instead, destroying it for good.

After the Mothwing Cloak has been acquired, Tiso can be found next to the well in Dirtmouth. He lightly hints at the Colosseum of Fools and expresses his urge to challenge the Knight.[2] Tiso never leaves a location until listened to.

Tiso can be found sitting on the Bench in the Forgotten Crossroads Stag Station, where he expresses his dislike for the Stag Stations' convenience and that a real warrior travels without help.[6]

Tiso is seen standing at the western shore of the Blue Lake, gazing over the water and expressing his dislike for peace and serenity.[7]

Tiso is found sitting on the Bench in the warrior's pit of the Colosseum of Fools, looking at the ground as if waiting. He needs to be interacted with in the Colosseum and then a Trial must be either completed or failed for him to move from his spot on the Bench. After this, Tiso's corpse is found lying on a ledge in Kingdom's Edge.

He was found by a traveling insect, he was half alive, so they took care of Tiso until he recovered from his near-death.
