Background
Saru is originally from another universe, possibly the same as Introbulus's. Or an early version of the universe created by Eerie I, I'm not sure which is better. Saru was raised by monkeys and thus battled in the form of a monkey, becoming a great warrior. He was a bit more mellow and content in this universe, but one day that universe was destroyed (depending on which universe, either by Introbulus or restarted by Eerie). Impossibly, Saru wound up being reincarnated in this universe. When he reached adulthood, he found he would not age any longer and also regained memories of the past universe.
Saru became consumed by angst and began to hate this universe, instead wanting his old universe back. Later on, when Eerie II was making some heroes, he decided to recruit Saru by giving him control over fire and the ability to create fire. Thus he became a the Legendary Fighter of Fire and teamed up with Introbulus, Cerulea and Bat-Ear Mirawk to drive Velvet Monkey, Akujin, Nijuka and Tenorvista back into S-Space. All along the way, Saru searched for some method that he could use to restore his old universe. In the meantime, he did find some comfort in the new universe when he had a romance with Cerulea.
Saru was later sent to infiltrate Akujin's MPVP around 3100 BC, posing as a member since he could pull it off with his loner appearance. Saru played a role in the MPVP members being sealed away, but he got sick of following Eerie's orders over time. He eventually left to follow his own agenda after learning of The Writer's Chair, which he believed he could use to reconstruct his old universe. He was motivated by the disappearance of Cerulea.
After a few thousand years with no leads, Saru found that Cerulea had been captured by Eerie in the mid-1990s. Saru was able to infiltrate Eerie's compound and save Cerulea. Saru convinced Cerulea to join him in letting go of all responsibilities and just doing whatever they wanted, especially in ways Eerie would not approve of. This led Saru and Cerulea to join up with the criminal organization Team Meteor in Pokemon: OG Version. Saru naturally used a Chimchar, which later evolved into an Infernape.
