Toushin Upsilon

About
Toushin Upsilon was one of the few remaining Toushin in the current era, since it was deactivated several years ago and stayed hidden in the floating continent Ylapu, guarded by Replica Misly.

Upsilon was the 20th Toushin to be constructed, and one of the last as a result. He was designed to retrofit Sergio Conp, a member of the Holy Magic Sect, and a personal friend of Freak Paraffin. Despite being a powerful mage, he was a man that specialised in hand-to-hand combat and a skilled martial artist. Once his will was transpanted into the Toushin Upsilon, Sergio started taking part in the Dark Lord War near the end of it. When M.M Rune entered in a blind fury, he ordered Dark Lords and "barbarians", humans incapable of using magic that weren't part of the Holy Sect, would all be targeted and regarded as enemies. Upsilon, following the unquestionable orders of the Magic Master, attacked a humble Kingdom living in the land, destroying it completely, being Replica Misly its only survivor since she was saved by Freak Paraffin.

Once M.M Rune was betrayed and   killed, Upsilon was considered too dangerous, since it carried the last order given by Rune to destroy the barbarians, so it was put to sleep in Ylapu, the Toushin Toshi linked to him, where Misly stayed to make sure it's never activated again.

During the events of Rance IV, Upsilon was re-activated by a Helman Platoon led by Bitch Golch, who wanted to use the Toushin as a weapon in a war to dominate all his opponents. However, Upsilon quickly dispatched Bitch and ended his life after he punched him away, decapitating him in the process. After this, Upsilon intended to follow the last directive given by M.M Rune of killing the "barbarians" which is basically everyone, since there are no humans belonging to the Holy Magic Sect anymore.

A party formed by Rance, Sill and the Rance Rescue Team sent from Leazas, were aided by Freak Paraffin to destroy several key components from all over Ylapu to weaken the Toushin and stand a chance in a fight against him. The party faced the Toushin in a final battle where they came out victorious, finally destroying it for good. However, the death of the Toushin resulted in the falling of the Floating Land Ylapu, since the destruction of the main Toushin body makes the whole system crumble, which forced the party to make a quick escape from the land.

Abilities
Being a Toushin, Upsilon was a terrifying force, capable of fighting on par with Dark Lords and way more powerful than even high-level adventurers. In battle, he was accompanied by two floating spheres he used to power himself up and restore energy. He could also use these orbs to attack with a powerful shockwave, a magical attack that covers a pretty wide range and inflicts high damage.

Despite this, Upsilon was primarly a physical fighter, relying mostly on his fists to battle his enemies. His strength was obscene and was an incredibly durable opponent, being able to withstand an incredible amount of punishment casually. As a Toushin, he was also tireless  fighter   that would never need to rest and could keep fighting indefinitely for as long as he's not completely destroyed.

A downside he had is that in order to stay in an optimal state for fighting, he required high amounts of energy that had to be drained from other sources. In order to do this, he had a specialised equipment behind him where he would keep a high-level mage to absorb his/her power. During his first encounter with Rance, he used Cynthia until she was rescued by Feliss without him noticing, which forced him to stay down in order to recover energy and allowing the party to escape.

Upsilon was a fearsome foe, and it took quite a number of high-tier fighters consisting of the adventurer Rance, Rick Addison, Leila Grecni, Shizuka Masou, Io Ishtar, Maria Custard, Athena 2.0, Kanami Kentou and Julia Lindum to defeat him in battle, and this was after he had been greatly weakened following the instructions given by Freak Paraffin, and that he lost his power source mid-battle, yet he still represented a very hard fight for the party. Had they faced a fully-powered Upsilon, the group would have stood little chance of survival, let alone of victory, much like how Freak Paraffin initially claimed.

Trivia

 * The Toushin Toshi linked to Upsilon, colloquially named Ylapu, is the one that became Toushin City after it fell to the ground, the main city where all the Toushin Toshi games take place.
