Vendra and Neftin were born in the Netherverse around the time Dimentio Winkiebottom began to take over their world. The Prog parents were warned by the Mobians about Dimentio's danger, and they used ancient space magic to banish Vendra and Neftin to Forest Moon Endor. Neftin and his sister, Vendra were abandoned on Meero Orphanage by their parents, and constantly bullied because of their race. Neftin trained in martial arts to defend his sister from bullies, but after Vendra acquired unique spacebending powers, they took the lives of criminals.
In Operation: NECSUS, Neftin and Vendra ambush Vweeb, Makava, Tronta, and Arianna on their mission to deliver Caesar Clown on Coruscant. He proves more than a match for the four, knocking out the other three before Vweeb. Vweeb was intimidated by Neftin's size and runs away, only for Neftin to flick and knock him out. Neftin then carries Caesar as he jumps away. He is later ordering around New Star Wolf as they go to capture Dimentia. He is with his sister for most other parts and is worried for her well-being, concerning her relationship with this "King of Space". When the main team came to Kreeli Comet, Neftin battled Sheila and Chris and knocked them out, along with Mason. He takes them to Zordoom Prison and puts them in a cell, as Vendra hopes to lure Nebula there so she can free her mother. They ambush Team Nebula when they arrive, but after Nefula refuses to team up with them, Sector V's cell is blown open by Sheila. They all get away as Vendra orders Neftin to stop Sector V, but he instead chooses to stop Nebula.Neftin tries to prevent Team Nebula from escaping, but Jerome shows up and engages him in battle. After a heated battle, Jerome comes victorious. Jerome proclaims it was all for buying Nebula enough time to escape, and it was his duty to protect his leader/sister. Remembering his own promise to protect his sister, Neftin surrenders, but requests Jerome's help in stopping Vendra from finding the Dimensionator and waking this King of Space. Jerome agrees if Neftin turns himself in afterward, along with Vendra, and Neftin promises. Later, Neftin brings Jerome to Planet Flora, where he unveils a hidden Zathurian Artifact. They show the artifact to Team Nebula later so they could retrieve the fragment on Mechanos. Later, Jerome and Neftin recruit Sector W7 to save the heroes from Reepor. They go to Coruscant to help stop the invasion, but Neftin was unable to stop Vendra from awakening the King of Space, who was Dimentio Z. Winkiebottom. Neftin accompanied the heroes in the voyage through the Netherverse, and when they reached the Nexus, he went with Vendra to fight Dimentio ahead of time. They were defeated, but when Dimentio attempted to take Vendra's Space Chi, Neftin rescued her and brought her to Nebula, so Vendra could give her her Space Chi. Vendra fainted, and Neftin was struck from behind by Dimentio.
They survived and were able to escape the Nexus, and as per his deal with Jerome, Neftin carried his sister to prison. However, Dandy first took them to Alien Registration.
