teenagers who protect the citizens of the United Planets. Shape-shifting member Chameleon Boy adopts the Protean creature as a pet, calling him "Proty". The affectionate alien proves useful to the Legion, and becomes quite close to Saturn Girl, as her telepathic abilities allow her to read its thoughts. Legion founder Garth Ranzz, the hero called Lightning Lad, dies. Scientists of teammate Mon-El's home world Daxam develop a machine that can use lightning to transfer life force from one person to another, reviving the recently dead but killing the "donor" in the process. Proty reads the mind of Saturn Girl, another Legion founder and a telepath, and learns she intends to sacrifice her life to revive Lightning Lad. Proty tricks her into becoming lost in a cave, disguises himself as her, and becomes the sacrifice who restores Lightning Lad to life. Following the 1985-1986 crossover Crisis on Infinite Earths, the Legion of Super-Heroes was reimagined as group of older, grittier characters living in a darker world of "Five Years Later". The "Five Years Later" era involved many revelations and revisions to characters. A story published in 1992 revealed the original Proty's sacrifice didn't resurrect Garth Rannz but did transfer the Protean's life force and consciousness into the young hero's body. Now inhabiting Garth's body, Proty lived his life as Lightning Lad from that point forward. This retcon was criticized by some fans as being inconsistent with several stories. This was later indicated to be the result of the Legion enemy Glorith creating an alternate timeline, removing the idea from Legion canon. Proty II Soon after the death of Proty, Chameleon Boy is shown as having another Protean as a pet. The pet is officially named Proty II or Proty Two, but many in the Legion simply call him "Proty". Proty II later becomes a member of the Legion of Super-Pets, a team of super-powered animals who live in the 20th century and were originally formed by the Legion when animal help was needed. The Legion of Super-Pets mainly operate as separate beings, only joining together when their unique team is required. Through time travel technology, Proty is able to join them on several missions. In the stories of the "Adult Legion" (taking place further in the future, when the teenage heroes are fully grown adults), Proty II is a full member of the Legion and is considered the pet of Saturn
