Subtitle: Underground Monster (地底怪獣 Chitei Kaijū ).
After the Underground People captured Shin Hayata, they released their ancient weapon, Telesdon. As Telesdon terrorized a city he emerged from underneath, the Underground People began hypnotizing Hayata to learn what they could from Ultraman. However, they underestimated Ultraman's power, as Ultraman transformed by himself and escaped to fight Telesdon. While Telesdon tried his best, he was of little match for the hero from M78 and was easily brought down by the Specium Beam after a brutal beating. Telesdon would return months later when Pigmon returned mysteriously in a toy store mumbling about something. The Science Patrol had his sayings analyzed and within time they found out that Pigmon, along with Telesdon and Dorako, were revived by a mystical kaiju by the name of Geronimon. Geronimon threatened to revive sixty monsters and conquer Earth. Telesdon awoke with Dorako on an island. The two clashed for a short time, but they were too tired to continue. The Science Patrol traveled to an island to defeat the creatures. After Dorako was killed Telesdon was quickly taken down as well by the Science Patrol's weapons, but they awoke Geronimon and made him angry.
His height is around 60 Meters tall. He weighs around 12,000 Tons.

Ultraman Powered Edit
This monster re-appeared in the series Ultraman: The Ultimate Hero.
A natural kaiju from underground, Telesdon was under the control of the underground people to do their bidding. Telesdon's movements caused irregular seismic vibrations and after the underground people captured Kenichi, they released him in Los Angeles. It did not take long for Telesdon's rampage to attract the attention of WINR as they quickly went to the scene. Before WINR could inflict any damage on him, Telesdon went back underground to prevent the sun from blinding his light sensitive eyes. Telesdon appeared the next night to continue what he started, but WINR and the government had set a trap for him by lightning up the entire city. However, because the light was not the sun, Telesdon was capable of resisting the lights. The military fired at him using tanks and howitzers, but Telesdon's armored plated body prevented them from so much as flinching him. Underground, Kenichi was able to turn into Ultraman Powered unintentionally thanks to the underground people and went to the surface to fight Telesdon. As Powered and Telesdon were fighting, WINR attempted to blind the creature with magnesium flares. After the flares were fired in Telesdon's face, Powered used the Mega Specium Ray to destroy him.
Ultra Galaxy Mega Monster Battle Edit
After the ZAP SPACY crew crash landed on the mysterious planet of Bolias, they surveyed the area, searching for any sign of life. Unfortunately for them, this planet was home to countless monsters! It wasn't long until the monster Telesdon emerged from the Earth, but he was not interested in the humans, for the monster Sadora appeared soon after to do battle! The crew distanced themselves as the two beasts battled, with neither side giving an inch. Their fight, however, attracted the attention of yet another monster; Red King! This juggernaut of a monster easily beat down both Telesdon and Sadora at once, and wasted no time in killing Sadora by choking it to death. One of the ZAP SPACY members, Oki, cheered for Red King defeating the two monsters, but after a deadly glance from the monster, it was obvious he didn't intend to rescue them. Kicking a rock in their direction, nearly killing them, Red King then picked up one of their vehicles, attempting to cursh them with it. The crew quickly shot at it with their ray guns, causing it to explode in Red King's hands! But this only angered him, and he began stomping toward them; their ray guns proved uselss, as they barely made him flinch. That's when Telesdon blindsighted Red King with a powerful tackle; the fight was still on! However, after another beating, Telesdon gave up, and retreated underground. Not long after the fight between Gomora and Red King, more monsters began showing up, one of them being Golza, another underground monster. During Golza's attack on the ZAP SPACY crew, Telesdon emerged once again. Before the two could even think about fighting each other, they were met with opposition in the form of Gomora. Gomora had trouble dealing with both at once, but Litora managed to lighten the load by attacking Golza's head! This allowed Gomora to finish off Telelsdon with its Super Oscillatory Wave. Telesdon tried to fight back with its flame breath, but to no avail; Telesdon was killed by the blast. However, when the monster Bullton appeared before ZAP SPACY, Telesdon was revived alongside Red King and Neronga. All three fought with Gomora and Litora. While Telesdon fought Litra, he accidentally killed Neronga with his flame breath, and then, Litora tricked him into attacking Bullton with his flames, which allowed ZAP SPACY to destroy Bullton with their Hyper Missiles. Telesdon was then killed by Gomora's Super Oscillatory Wave, this time for good.
