Terios

Description
Terios is known as a dark, serious and brooding by most, an intimidating silhouette that juxtaposes the likes of Needlemouse, Venice and Tiara. He watches over the guests from the shadows, often appearing in crucial moments to save them from danger, as he did with Classic and Eggy when they were attacked by Metal Robotnik.

The House of Needlemouse
Terios is a regular character in the main story, appearing frequently out of nowhere in The House or The Depths, though he sometimes takes absences to deal with business in The Citadel and the wider Multiverse.

The House of Needlemouse: Mirror Shards
Terios, according to SinFrog, will appear in Mirror Shards at some point.

'A Day on the Little Planet'
Terios appears in the Swap AU side-story, long before the main story has begun. He is accompanied by Tiara and the same incarnation of Sir Percival who appeared as a high ranking Patroller during Metal and Mephiles' Bizarre Adventure.

Chaos Mastery
Terios has been shown to have mastery over the Chaos Emeralds, being able to perform techniques that would usually require 3 or 4 Chaos Emeralds with only two, for example.

Immortality
Like Needlemouse, Venice and Tiara, Terios is assumed to be completely immortal as he has lived for billions of years throughout countless battles.

Standard Abilities+
As the ancestor of Shadow the Hedgehog, he has naturally enhanced strength and speed, despite being only a prototype of the Ultimate Lifeform. As well as this, he has had billions of years worth of training.

Super Terios
As well as prior confirmation by SinFrog, Terios has told a story in which he went Super to face against a specific Dark Gaia who went out of control and was growing to the level of a multiversal threat.

The Concept Crew
Terios is in a polyamorous romantic relationship with Needlemouse, Venice and Tiara. Terios, while he struggles to express his emotions, has been said to be a good partner who cares greatly for them.

Ess
Terios once took Ess on a 'field trip' to The Citadel, in which he trusted Ess with information on The Citadel, as well as pleading for him to care for Shikurai, implying that he is either very trusting towards him or very desperate.

Salve
Terios is implied to be an older brother figure to Salve, similar to the relationship between Sonic and Cream in canon. Despite this, she still calls him 'Mr Terios'.

Classic
Terios sees great potential in Classic, and wishes to see him reach the true heights of his power.

Fleetway
Similar to Classic, Terios wants to see Fleetway become a powerful force of justice, but it's more personal than that, he sees himself in Fleetway, but the specific reasons why haven't been fully disclosed.

Madonna
Terios and Madonna have been shown to bicker like siblings with varying levels of actual severity. They've known eachother for a very long time, and Madonna knows him well enough to understand his often hard to read moods.

Quotes
"I don't hate them, I don't want to see them suffer, I just..."

"I want them to know what they are, and what they can do."
