Kokonoe: Born January 30, 1966, in Morioh Town within Japan's M Prefecture in the city of S, Yoshikage Kira longed for a simple life and did not wish for it to be interrupted. Even after the deaths of his parents though, Kira's life has been relatively normal as he worked as a seemingly unremarkable salaryman.

Junko: One that has a habit of collecting his own fingernails... gross...

Kokonoe: Right... while he may have seemed like a normal man on the outside, he managed to hide his true intentions for years. While he may seem like a normal businessman, he was actually a serial killer who was sexually attracted to... woman's hands.

Junko: Double gross! Not that I'm complaining of course. The guy's incredibly smart with it too.

Kokonoe: Kira has a genius intellect, deliberately making himself seem to be not as smart as he actually is. He's a devious schemer, cunning and pragmatic. He's always thinking three steps ahead and his paranoia has him make sure to leave no evidence behind.

Ann: That was difficult to do with his first victim... but it was a lot easier with his Stand, Killer Queen!

Kokonoe: The manifestation of Kira's psyche. It can be summoned at any time and is invisible to those without a Stand, those who can't see spirits, or those who don't have psychic powers.

Ann: And his Stand is incredibly strong.

Ann: It's just as strong as Star Platinum, which can break artificial diamonds! It can also trade blows with Crazy Diamond, which was strong enough to get Star Platinum to focus on defense!

Junko: It's also crazy fast!

Ann: He's easily capable of matching faster-than-light speeds, being able to keep up with Stands like Star Platinum, which can move at 1500x faster than light speeds!

Kokonoe: Well, there is speculation on whether or not this calculation is a bit of a highball estimate, but it is true that at least the stands can move faster than light. The same probably shouldn't apply to Kira himself unless we consider his reaction speed.

Ann: Killer Queen can easily block all of Echoes Act 3's punches and swatted away Shigeki's Harvest, which can split into 500 copies!

Junko: It's also incredibly durable!

Junko: It should be far more durable than Kira, who can keep going after having his hand cut off, getting shot in the chest by Stray Cat, getting stabbed by multiple glass shards to the back, and even getting beaten to a pulp by both Star Platnium and Crazy Diamond respectively. 

Ann: Its main ability is its Bomb Transmutation.

Ann: An overpowered ability that lets him turn anything or anyone he touches into a bomb that he can detonate whenever he wants. He's able to set traps this way. If you touch an object that he's made a bomb, you end up blowing up instead. And since the explosion destroys the target on an atomic level, it leaves no evidence of the murder.

Junko: Yeah, but that's just one of the abilities of Killer Queen right?

Ann: Yep! The second is Sheer Heart Attack!

Ann: This miniature tank is dispatched from Killer Queen's left hand. It's an automatic stand and has great range, tracking its target based on their heat signature. It follows the target to blow them up and won't stop until the target is dead.

Junko: And good luck trying to get rid of it! The thing's nigh-indestructible! Star Platinum couldn't even scratch it after stopping time and pummeling it non-stop

Kokonoe: And after being stabbed with a Stand Arrow, Killer Queen got an upgrade and a third ability...  Bites the Dust.

https://youtu.be/HZ9JOibEAwE

Kokonoe: I didn't mean the song by Queen... but alright. This ability allows him to implant a miniature version of Killer Queen into someone with whom he's told his secrets. If someone interrogates this host about Kira, the stand will cause everyone in the field of vision to explode. After this, a time loop lasting from an hour will start and only Kira can stop it.

Junko: Nobody will have memories of the events except the host. Not even Kira would be 100% aware of what happens during the time loops! But only he can stop them! The victims will die again the same way at the same time even if they don't ask about Kira or are somewhere else!

Kokonoe: And it protects the host too, so it's not like the host can just kill themselves to stop the time loops.

Ann: But even if that doesn't work, he still has one more trick up his sleeve, and that's Stray Cat.

Junko: This Frieza-looking plant used to be a regular cat, but it died before getting struck by a Stand Arrow and turned into a plant. Kira managed to tame the thing and keep it as a plant!

Kokonoe: It has the ability to manipulate the air to create air bubbles to attack enemies. Kira can place Stray Cat in Killer Queen's abdomen, allowing him to fire small, invisible, exploding air bullets for long-range attacks

Ann: He can also make a barrier of air strong enough to block hits from Crazy Diamond! But he's not invincible.

Junko: Aside from the fact that any damage put on Killer Queen reflects onto Kira and vice versa, he can be pretty arrogant at times. Even though technically Kira himself isn't a fighter, much preferring to outsmart his opponent then get in a personal conflict. Because of this, while Killer Queen can keep up with other stands, it's not necessarily as physically strong as them.

Ann: Also, Another One Bites the Dust requires a non-Stand user victim to use and as long as it is active, Kira can't use his Stand. Kira can also only detonate one bomb at a time, Sheer Heart Attack can be tricked by greater heat sources, and if Stray Cat doesn't have sunlight or is taken away from Kira, he loses the ability to make air bombs.

Kokonoe: There's also the issue that Killer Queen will grow weaker if Kira is too far away from it.

Junko: And yet even then, he's got plenty of experience behind his belt. With his genius intellect and highly destructive Stand, there's no doubt that Kira is one of the most deadliest and dangerous villains in JoJo.

Kira: My name is Yoshikage Kira. I'm 33 years old. My house is in the northeast section of Morioh, where all the villas are, and I am not married. I work as an employee for the Kame Yu department stores, and I get home every day by 8 PM at the latest. I don't smoke, but I occasionally drink. I'm in bed by 11 PM and make sure I get eight hours of sleep, no matter what. After having a glass of warm milk and doing about twenty minutes of stretches before going to bed, I usually have no problems sleeping until morning. Just like a baby, I wake up without any fatigue or stress in the morning. I was told there were no issues at my last check-up. I'm trying to explain that I'm a person who wishes to live a very quiet life. I take care not to trouble myself with any enemies, like winning and losing, that would cause me to lose sleep at night. That is how I deal with society, and I know that is what brings me happiness. Although, if I were to fight I wouldn't lose to anyone.
