'''Kusuke Saiki ''(Japanese: <ruby><rb>斉</rb><rt>さい</rt><rb>木</rb><rt>き</rt></ruby>　<ruby><rb>空</rb><rt>くう</rt><rb>助</rb><rt>すけ</rt> , Hepburn: Saiki Kūsuke)''''' is [[Saiki Kusuo|Kusuo's]] older brother, and the son of [[Saiki Kuniharu|Kuniharu]] and [[Saiki Kurumi|Kurumi.]] He is a super genius who likes to invent machines/devices, and he's 2 years older than Kusuo.
==Appearance==
[[file:Chara Kusuke.png|left|100px]] Kusuke, like Kusuo, was born with a different hair color than his parents. He has blonde hair and slightly darker eyes. He wears his "Telepathy Canceler" whenever he is around Kusuo, but he still somehow knows what Kusuo is trying to say. When working, he is mostly seen with his machines, wearing a typical white lab coat worn by scientists. When in school, he wears a long black robe with a white collar buttoned up, and while on his days off, he wears normal clothes such as a t-shirt and pants.
==Personality==
[[File:Kusuke_ahyu.png|thumb|left]]Kusuke is prideful and competitive when it comes to Kusuo. He would have done anything to win against him when they were kids. However, he would always lose against his little brother. Thus, he became addicted to playing/fighting with Kusuo. Kusuke is a sadist, as shown when he enjoyed seeing Kusuo, [[Kaidou Shun|Shun]] and [[Nendou Riki|Riki]] being chased by crowds of people. Kusuke is also obsessed with Kusuo and can be attention seeking and selfish. This is best shown when he made a time machine to go back 20 years in the past when Kusuo was still alive (in this chapter, they were in a parallel universe where Kusuo had died<ref>Saiki Kusuo no Psi-nan [[Chapter 126]]</ref>) and when he made [[Teruhashi Kokomi|Kokomi]] cry by saying that she and Kusuo were not fit for each other.

He is also deceitful, always showing an angelic smile towards their parents. He ignores his father, just like Kusuo. Kusuo always thought that Kusuke hated him, but Kusuke cleared this up and told Kusuo that he only liked to tease him.

Like his brother, he doesn't appear interested in love, as he showed himself immune to the beauty of Kokomi and was rather blunt in talking to her.

Despite Kusuke's competitive nature, he still is caring to Kusuo and his mother, he won't frame family for something they haven't done, and most of their competitions are just teasing. This is an exception to his father for some reason.

==History==
Kusuke was born on June 16th and was raised by [[Saiki Kurumi]] and [[Saiki Kuniharu]]. At 1 month old, he spoke his first words and quickly was able to communicate with his parents. He then was able to write and do math at the age of 2. Not long afterwards, his younger brother, [[Saiki Kusuo]], was born. Kusuke always competed against his younger brother and lose every single time.

Sometime in middle school, he, along with Kusuo, created the control devices that Kusuo wears.<ref>Saiki Kusuo no Psi-nan [[Chapter 103]]</ref> At the age of 14, he leaves to England and studied in Cambridge,<ref>Saiki Kusuo no Psi-nan [[Chapter 104]]</ref> getting a masters and PhD.<ref>Saiki Kusuo no Psi-nan [[Chapter 105]]</ref>

==Trivia==
*Like the rest his family, Kusuke's name is a pun on the word Psychics (サイキックス ''Saikikkusu'').
**"suke" is common in Japanese given names for males.
*He, along with Kusuo, created the control devices that Kusuo wears.
*He has an IQ of 218.<ref>Saiki Kusuo no Psi-nan [[Chapter 104]]</ref>
*Similar to his brother, he is immune to Kokomi's beauty.{{clr}}
