Yu Yu Hakusho is a series full of some of the most amazing moments in anime. While watching this anime, it's literally not possible to find yourself full of enjoyment at one time or another (If you haven't seen it yet it's one of the best anime on Hulu right now!).

Another thing impossible to dislike is the many characters introduced throughout the show. Whether you love the heroes or the very dangerous villains, there's someone for everyone in Yu Yu Hakusho. However, there may be some things you definitely don't know about this cast. If you want a few examples stick around for the list.

11 PU'S PHOENIX FORM IS CONNECTED TO YUSUKE

This may be one of the more obvious details you may have missed in your viewing of Yu Yu Hakusho. Pu is a small, cute, bird-like spirit beast. As we learn, spirit beasts are creatures that copy the personality of their master. This means Pu's personality is, of course, that of Yusuke Urameshi's.

During some of the near-final moments of the series, Yusuke finally awakens to his demonkin form. Once this transformation takes place Pu transforms as well from his small form to that of a giant phoenix. This was in direct connection, and symbolic, of Yusuke's awakening.

10 JORGE IS AN ANIME ONLY CHARACTER

As loved as he is, Koenma's sidekick is actually not originally a part of the Yu Yu Hakusho series. In fact, he wasn't supposed to be a character at all. For reasons unknown, Jorge was introduced in the anime even though he was never in existence in the entirety of the original manga.

This inclusion is amplified further when we find out that Jorge is not only a character in the anime but also has been confirmed to be the narrator of the anime version as well. This is confirmed in episode 111.

9 YUKINA COULD BE AS OLD AS 99 YEARS OLD

Yukina and Hiei's demon race have a much longer lifespan than that of humans. Their race can live far beyond the age of 100 while still retaining a youthful appearance. It is also confirmed in the anime and the manga that their race gives birth to a new baby girl every 100 years.

Which character hasn't had a baby girl yet that belongs to said demon race? Yukina of course. That means that while her specific age isn't confirmed, it can be inferred that the icy twin of Hiei could be 99 years old or younger.

8 GENKAI IS ONLY A SMOKER IN THE ANIME

This is another instance of the anime having a bit of difference from the original manga run of the series. Due to the omission of Yusuke being a smoker in the anime for unknown reasons, certain events in the story had to change.

One of these events was the early battle of Yusuke versus Kibano. Instead of the cigarette being used in his defeat belonging directly to Yusuke, it was a cigarette belonging to Genkai herself. Rather than have Yusuke take his own cigarette, Genkai throws her cigarette at Yusuke and he uses it later on after spotting it on the floor.

7 KOENMA'S NAME IS A PUN

The name pun seems to be an ongoing thing in old Japanese anime and manga. These name puns are actually some of the most missed references in the Dragon Ball series. Much like those names, Koenma's name is a very well hidden pun, especially if you aren't experienced in Japanese culture, language, and mythology.

If you didn't know, Koenma isn't the sole ruler of the spirit world, but is second in command. The main ruler of this world is Koenma's father making Koenma the co-ruler. The co-Enma, aka the co-ruler of hell.

6 BOTAN IS BASED ON GREEK MYTHOLOGY

Botan is a core member of the spirit world "workforce" and a key character in the Yu Yu Hakusho series. In fact, without her, there would most likely be no Yu Yu Hakusho. Botan is in charge of the job of ferrying souls back and forth between the human and spirit world. While many may think this is similar to the grim reaper, that isn't the case.

Botan is actually inspired by the character of Greek mythology, Charon the Ferryman. This character is the ferryman of Hades and is given the job of taking the recently deceased souls across the River Styx to the afterlife.

5 IT ISN'T KNOWN EXACTLY WHEN YUSUKE AND KEIKO FELL IN LOVE

While they are the series main couple and the romance everyone was waiting for, it isn't ever really stated or shown when the two finally caught true feelings for each other. Since the beginning scenes with the two, we are well aware of the feelings that are there, but it's never explicitly stated when that all started.

In the manga however, it is somewhat shown that they were destined to be since childhood as the two have always cared for each other and been there for one another ever since.

4 HIEI WAS MEANT TO ONLY BE A VILLAIN

As any Yu Yu Hakusho fan knows, Hiei originally only appears very early in the manga and anime at a mere episode six as a small starter villain. This was as early as the Spirit Detective arc when Yusuke was still getting the hang of his new occupation. However, many fans may not know that this well-loved character wasn't supposed to show up at all after that first appearance.

The short and short-tempered dark ally to Urameshi gang was only supposed to be a one-off villain for Yusuke to beat up on much like the rest of the Spirit Detective arc's other villains. Hiei was just so popular the writer brought him back on as a member of the main cast.

3 KURAPIKA FROM HUNTER X HUNTER IS HEAVILY BASED ON KURAMA

Many are aware of the fact that the creator of Yu Yu Hakusho, Yoshihiro Togashi, is also the mastermind behind the hit anime and manga series, Hunter X Hunter. One very telling thing when it comes to this shared creator is the character similarity between Kurama and Kurapika.

Both are the master strategist and tactician of their team, both wear similar clothing, both control a whip-like weapon, both have very similar personalities, both have androgynous looks leading to them being mistaken for women, and both are calm while having inner demons and darker missions. They both are also the only main characters of the two series' casts to share beginning syllables. Kura-pika and Kura-ma.

2 KUWABARA'S NAME COMES FROM TWO BASEBALL PLAYERS

When on the topic of the character, Kazuma Kuwabara, Yoshihiro Togashi has confirmed that unlike the simple origins of names like "Hiei" and "Kurama "(he just thought of those two names randomly on the spot) he took two names of two Japanese Professional Baseball players and mixed them up to get Kuwabara's.

The baseball inspiration for his character goes further beyond just the name. In the manga during the Genkai Tournament, Kuwabara actually shows up dressed in a baseball jersey, unlike the anime. In multiple scenes, he's used his patented spirit sword as a baseball bat as well.

1 YUSUKE URAMESHI IS A SINGER

Spirit detective, Earth's savior, ghost, deadman walking, tournament champion, and singer. Yusuke has quite the portfolio, doesn't he? While he isn't seen dropping any vocals throughout the manga or anime, Yusuke is actually quite the singer when it comes to his animated series.

Several songs on the Yu Yu Hakusho anime soundtrack are credited to the spirit detective himself. In fact, just about 13 tracks feature him on vocals singing his spirit out. Other songs featuring him also include a duet with his girl Keiko and a group song with the rest of team Urameshi: Hiei, Kuwabara, and Kurama.
