The Best Episodes Directed By Sean Song

While traveling through the woods, the ThunderCats come across a group of Petalars - small plant-like creatures whose lifespans are only one day. Lion-O befriends the young Emrick as he and the others try to figure out a way out of the woods and return the Petalars to their home. Meanwhile, Slithe and his lizard army are hot on the ThunderCats' trail to eliminate them.

The ThunderCats accompany Panthro to Cloud Peak Mine to search for Thundrilium for the Thundertank. Along the way, Panthro and Grune's past is explored, from their first encounter to the reason behind Grune's betrayal.

Lion-O ventures into the Book of Omens where he becomes the incarnation of his renowned ancestor, the valiant Leo, who led the rebellion against Mumm-Ra in a previous millennium.

As Tygra and Panthro work on the ThunderTank, Lion-O is searching for supplies and encounters a mysterious Drifter who helps teach a few important lessons. After showing off The Sword of Omens in town, Lion-O is challenged by a man known as The Duelist and must overcome himself in order to win.

Lion-O, always outdone by his adoptive older brother Tygra, undergoes the ritual to be chosen by the Sword of Omens as the next king of Thundera. His father, Claudus, does not feel his son is ready because he is too lenient and easily distracted by flights of fancy like the myth of ancient technology. Soon after, King Claudus welcomes the return of his friend Grune and holds a celebration in both his honor and in memory of the fallen Panthro. During the event, Lion-O defends a pair of captured Lizards and convinces his father to release them.

Jackie is excavating some ancient armor when Uncle reveals it is the Armor of the Gods. This ancient suit of armor was worn by the Eight Immortals in their battles against the Demon Sorcerers. It proves quite convenient when the Dark Hand travels to Spain to find the portal of Dai Gui, the Earth Demon. However, sealing Dai Gui is complicated, as Jade used a sleeping potion on Uncle because of his constant complaining.

Jade, Uncle, and Jackie escape from Shendu's palace with a few talismans taken from Shendu. Using Jade's memories of the Immortal symbols, they embark on a mission to find the other members of the J-Team and manage to banish half of the Demons in the process. Realizing what has transpired, Shendu and the other three remaining Demons make a final stand at Australia to prevent history from being corrected.

After escaping their destroyed city with the Sword of Omens, the team encounters the Fishmen, who sail the quicksand sea in search of a massive sea creature. The ThunderCats’ quest is to find the Book of Omens … but Lion-O is more interested in revenge on Mumm-Ra.
