Treasure Eating Stingray

Treasure Eating Stingray is an unique Shinheuh that belongs to Po Bidau Gustang, The Family Head of Po Bidau Family. When the Hidden Floor was on the edge of collapsing, the real King Zahard mentioned it as Gustang's "Treasure Eating Stingray".

Appearances and Personality
It looks like a large stingray with a hole instead of a head, it is blue with a white-gray belly. The large hole is used for attacking or to suck in a treasure that it or its owner desires.

History
It seems that Treasure Eating Stingray is an unique Shinheuh that has been owned by Gustang for a long time, since Zahard was able to recognize and identify it in the Hidden Floor although the Stingray was using its "invisible" ability.

The Hell Train: New Power
After Baam and friends leaving the Floor of Death, Gustang returns all the stolen souls back to its place in the three waterfalls. The chapter later showed Gustang talk by himself. It seems that he was talking to a "mysterious person" over the phone or something. Gustang then stated that he gave that mysterious person's pawn (Rachel) a "special gift".

The chapter then showed Rachel who just woke up from her sleep in the train after suffering the Grand De Lee's poison which has already been healed by Gustang. At first, we only saw a small stingray fish in front of Rachel. The small stingray fish also visible to Rachel's eyes. But when Rachel intended to touch the stingray, it avoided Rachel, quickly flying away and disappeared out of nowhere right in front of Rachel. Right after the stingray disappeared, Baam opened the door of Rachel's room. He came to visit Rachel, asking about her condition and explaining about their next destination to the Hidden Floor. When Rachel hears that Baam wanted to give her a chance to obtain the "second thorn fragment" in fair competition and decide who will be the true owner of 'it', Rachel was pissed, she clenched her fist, saying that she doesn't need Baam's pity. After their conversation ended, Baam then proceeded to walk outside the room and standing in front of the door while thinking about his decision when suddenly he got a mysterious scar on his cheek. Baam then asked why he bled. It turns out that the stingray was right beside Rachel the whole time when she had a conversation with Baam and it changed its form to a big size stingray. It's still not clear how Baam got scratched, but that stingray might have been the cause of it.

After that, Androssi Zahard come rushing mad and stomping her foot to complain to Baam about his plan to take Rachel to the hidden floor. When Baam tried to explain to her, Androssi became angrier, saying that she didn't want to hear any excuses. When Baam confirmed Androssi's guess that he was excusing Rachel because of Hockney's last picture, Androssi then decided that she would go meet Rachel and get the picture back for Baam and find out all secret that Rachel has been hiding. After some discussion in Rachel's room, Androssi then asked Rachel to come into a different room. When Rachel asked what are they doing in that room, Androssi pulled out her Arms Inventory, drawing a red needle out from it and then gave it to Rachel, asking her to prove her fighting skills. Rachel immediately rejected Androssi's request and said that it's obvious who will win. Upon hearing this, Androssi launched a powerful kick just right beside Rachel, giving her warning to get serious. Although Rachel was being attacked, the stingray didn't do anything to protect Rachel in front of Androssi's threat. When Rachel was about to stand up, Androssi quickly launched a knee kick to Rachel's stomach, sending her flying away and hit the wall. Again, the stingray didn't do anything to protect Rachel.

Just right when Rachel showed her angry face, indicating that she despised Androssi, the stingray finally came out, with foreshadowing of red color aura. Outside of the room, David Hockney suddenly come. When Baam asked him what is he doing here or whether it's because of the picture, Hockney confirmed that he was indeed looking for the picture, but he also said that the closer he got with the picture, he had a bad feeling about it. Hockney wasn't completely sure but he said that he sensed that "someone near death" around that place.

The Hell Train: The Hidden Hidden Floor
After she met Mirror of the Past in a space dimension for assessment, Rachel entered the real Hidden Floor but ended up in a totally different place than the others. Rachel ended up in the most secretive place called the "Hidden" Hidden Floor. it turns out that Rachel passed out unconscious as the Stingray brought her to the room of Big Breeder Chung. The Big Breeder described it as a "mysterious power" because the Stingray was in invisible mode. After Rachel woke up from her sleep, she begun to confront Chung and asked where she is at and also other information about Hidden Floor. After hearing that the Big Breeder used some kind of virtual reality machine to create virtual avatar and use it to control the other Hidden Floor, Rachel wanted to try to use the machine. When the big breeder tried to stop her, he was attacked by the Stingray.

The Hell Train: Three Orders
When Baam came to confront and warn Rachel for putting Khun Aguero Agnis into comatose condition, Baam attacked Rachel and break her Lighthouse Barrier defenses. Suddenly the Stingray attacked Baam with wind shock wave. Baam was surprised and mentioned that "he did not see anything but there was something protecting Rachel". The stingray attacked again but Baam quickly dodged the attack. Baam then launched Orb - Shinwonryu attack but the Stingray runs away and disappeared.

Power and Abilities
The Stingray may be a Shinheuh, but it might also act as an inventory being able to "store" several items in its stomach. However, it has also basic combat capabilities which it uses to gather treasure and protect its owner. It seems to have some form of intellect since when it found the fight with Twenty-Fifth Baam unfavourable it backed down and escaped. It also holds loyalty or is forced by Gustang to do his bidding, since it only collects the items that Gustang wants.

Invisibility
The Stringray is invisible for most of the times. Its presence cannot be detected. Even by Androssi Zahard and Twenty-Fifth Baam.

Shinsu Control
The Stingray can burst or blast a very powerful shinsu Wind tornado shock wave from its hole. It can make even crack on the ground like an earthquake.

Shinsu Teleportation
The Treasure Eating Stingray possess the ability to teleport on its own and it can also teleport other beings or objects. In special occasion, it teleport someone at the order of its owner/master, Po Bidau Gustang. After Baam survived and escaped from the Battle of The Last Station, Rachel and Ha Yura were captured by Division Commander Ha Cheonhee and being held captive inside Cheonhee's warship. Before they can leave the Floor, the Po Bidau Family Mothership suddenly appeared right in front of Cheonhee's warship. Gustang then commanded the Stingray to rescue Rachel from inside Cheonhee's warship. The Stingray then teleported Rachel and Yura right in front of Gustang.

Later, it would showcase the ability again to teleport Lo Po Bia Perseus right in front of Gustang to easily incinerate him when he attempted to flee the Po Bidau's Mothership.

Vacuum
The Treasure Eating Stingray also possess the ability to "capture" and store objects inside its body. As seen where it had successfully stolen Zahard's Bracelet that originally kept in the Hidden Floor by Zahard (Data) and Zarhard's Ring originally belonging to Ja Wangnan by vacuuming it into its mouth. The suction itself is powerful and fast enough that the Real Zahard, who had projected himself into the Hidden Floor, was unable to stop it.
