Xander works alongside his fellow Rangers at the Rock-Porium, where he prefers to assign tasks to his co-workers, rather than to actually work himself; he refers to this as "supervising." He briefly clashed with Daggeron when the latter became the Rangers' mentor, seemingly out of the blue. Xander's overconfidence and inflated ego have gotten him into danger on several occasions, but his willingness in owning up to his mistakes has earned him several spell codes. After the final battle against the Master, he was promoted to manager of the Rock-Porium.
As the Green Mystic Ranger, Xander wields the power of the earth and can call upon the Mystic Muscles, magically bulking up his muscles to gigantic proportions. His weapon is the Magi Staff Axe. He was the first Mystic Force Ranger to use the Mystic Force Fighters spell code and also owns a Mystic Racer. Xander's Titan form is the Mystic Minotaur, which makes up the bulk of the Mystic Dragon and Titan Megazord formations. As the Green Legend Warrior, Xander gains the Mystic Lion Staff which allows him to cast the Rock Slide spell and allows him to join with Vida, Madison, and Chip to become the Mystic Lion.
Xander appeared alongside former Power Rangers Tori Hanson, Kira Ford, Bridge Carson and Adam Park in the 15th anniversary special Once a Ranger. When the new villain Thrax disabled the Operation Overdrive Power Rangers' link to the Morphing Grid, Xander was one of five Rangers summoned by the Sentinel Knight to defend Earth in their stead. He was the first of the veteran Rangers to make his entrance, ensnarling Mig the Fearcat in a mass of vines. He later attempted to use "Plan Xander" on a group of Chillers when he and the veteran Rangers were ambushed by them at Angel Grove and was, not surprisingly, unsuccessful.
During the climactic battle with Thrax and his allies, Xander teamed up with Will and Dax against the Fearcats. He drew the attention of the Fearcats, using the Mystic Force Fighters to deflect their laser blasts before punching the villains to the ground, giving Will and Dax the openings they needed to use the Drive Slammer and Drive Vortex for the win. After the Rangers' victory, he told the Operation Overdrive Rangers that they were welcome to drop by the Rock-Porium anytime, and he would give them a 10 percent discount.
"Hi. The name's Xander." (repeated line)
"Hi. Xander Bly. Whatever the problem is, I'm sure we can talk this one out." (winks and gets blasted) "Not a big talker, I see." (Trying "Plan Xander" on Necrolai)
"When I came to this country, I didn't know anyone. No one wanted to know me. I was the new guy with the silly accent, picked last on the school teams. I was teased mercilessly. It takes time to find your place. I understand loneliness. I understand leaving your friends behind. But you're not alone, Nick. You've got us. We're your friends. We're your mates. Your family." (telling Nick about his past)
"You can go to the complaints department later, Vida." (after Vida expresses disgust at learning her uniform is pink)
"Leelee's mum is hot." (after Necrolai takes on a human form)
"Seems your prince has arrived." (to Madison, referring to a frog that had hopped onto her shoulder; the frog was actually Daggeron under a curse)
"Nice. Way better than a hollow tree. This is good." (comparing the Operation Overdrive Command Center to Rootcore, the Mystic Force base; he referred to Rootcore as 'a hollow tree' )
"It feels good to get back to my roots." (after attacking the Chillers with a mass of vines and roots at Angel Grove)
