- — Haseo — 
Haseo (ハセヲ, 
Haseo) is an 
Adept Rogue known as the 
"Terror of Death" (死の恐怖, 
Shi no Kyōfu). Haseo is the main character for 
.hack//Roots and the 
.hack//G.U. He is in search of the PK 
Tri-Edge. 
 
Appearance
1st Form Haseo's initial form is a 
Twin Blade.  He has red eyes, shaggy silver hair, an exposed midrif and wears a  black leather wardrobe. His shoulders are decorated with wave tattoos  and the marks on his face are shaped like red lightning bolts. 
2nd Form For his second form his midriff is now covered  and additional bronze-like metal plating was added to his arms and hips.  He also has a metal decoration on his back. The marks on his face are  jagged with a straight line underneath. In this form, he gains access to  his Edge Punisher job. This is also the form in which he first awakened  
Skeith. 
3rd Form Haseo's appearance changes drastically in his  third form (he is quoted as looking "awesome" by Silabus and Gaspard  after completing the Job Extension quest). The bronze-plating components  are now gone, in their place being spiky black and red-gradient tipped  protrusions littered all over his armor. His torso and abdomen are now  once again no longer covered by armour, now covered by a tight, leathery  purple piece with a red tattoo on it, akin to his initial 1st form. His  facial marks are two curves on his cheeks, each with multiple juts  coming out as they run down his face, likening to scars. In this form,  he gains the ability to use his Flick Reaper job, Weapon Change, and  Skeith the 2nd. 
Xth Form During 
Redemption with help from 
Zelkova, Haseo unintentionally breaks system rules and communicates with his 
Avatar  to obtain a fourth Form. Unlike previous forms Haseo has gold eyes  (although they remain red during game play), wears a white striped  shirt, pants and has various plates scattered over his arms, legs and  hips. His shoulders are bare and have gear shaped symbols on each side.  Similar to 
Kite  there are triangular shaped marks on each side of his face. The Xth  Form gains the ability to use Skeith the 3rd, drain heart and dash. The  initial weapons he is granted with are a pair of dual guns, the DG-X (in  reference that they are dual guns, and come with the Xth form). 
B-st Form In 
Trilogy Haseo obtains a unique and demonic form due to his hatred. The 
B-st Form  is similar to his 3rd, but appears more primal. In addition to growing a  tail and the spikes on his armor become more jagged. Haseo wields dual  Broadswords, gains the ability to tear into areas and summons hundreds  of weapons to launch at the opponent. 
Novel Form Haseo gains a new unnamed form in the 
G.U. Novels when he faces and accepts his past as 
Sora  and Skeith. He wears white armor with wings and carries Skeith's wand  as a weapon. This form's full abilities are unknown, since Haseo is  never shown using it in normal combat. 
Personality
Haseo is a cold person, but holds a soft spot for 
Shino.  He finds it hard to get close to people. Though not as warm, he is a  great leader and is willing to risk everything for his friends. When  Shino was attacked by Tri-Edge, he stopped at nothing to find out what  happened to her and tried get his revenge. As he progressed, Haseo  learned to trust his new friends and grew as a person. 
Despite his profession as the "Terror of Death" in 
Roots, Haseo hates rumors and 
forums, disdainfully calling it "idle chatter". His preferred sources for information are 
PKs and "professional victims" like 
Bordeaux and 
Midori, respectively, as they are far more likely to encounter the mysterious PK, 
Tri-Edge, than the rumor-mills on the BBS.
