Gollum
Gollum is a fictional character from J. R. R. Tolkien's legendarium. He was introduced in the 1937 fantasy novel "The Hobbit", and became an important character in its sequel, "The Lord of the Rings". Gollum was a Stoor Hobbit of the River-folk, who lived near the Gladden Fields. Originally known as Sméagol, he was corrupted by the One Ring and later named Gollum after his habit of making "a horrible swallowing noise in his throat".
Krillin
Seven years later, Krillin has quit fighting, settled down with #18, with whom he has a daughter named . This left Goku confused, until Krillin explained that Android 18 is a cyborg (meaning she is human still), and she was able to have a baby with him. However, after learning of Goku's return from the afterlife to compete in the 25th Tenka'ichi Budōkai, he decides to also participate, also being encouraged to do so for the money by #18. During Goten and Trunks' match, Krillin worries that Trunks' energy attack will hit the crowd. Krillin wins his sole match, against Pintar, during the competition with ease. After the Kaiō-shin enlists several of Krillin's friends to help him defeat the wizard Bobbidi, Krillin joins them, in doing so forfeiting his entry in the tournament, but is stopped from assisting any further thanks to Dabura turning him into stone with his spit. Upon Dabura's death however, Krillin is freed and he saves Goten and Trunks from the impact of Vegeta's self-explosion. Krillin later evacuates Earth after Majin Boo's awakening. When Boo has transformed, he finds Krillin's groups and kills them. During Goku and Vegeta's fight against Boo, Krillin is brought back to life by the Namekian Dragon Balls and gives his energy to Goku's "Genki-Dama" attack, which is used to destroy Boo.
