Marrow Amin/History

Background
Marrow is the youngest and newest addition to the Ace-Ops team. Prior to the start of the series, he graduated from Atlas Academy, joining the military as a Specialist. He and his team were called into Mantle because of reports of a stolen Atlesian airship entering its airspace and because of the unauthorized use of weapons by civilians. The culprits were Team RWBY, Team JNPR, Qrow Branwen and Oscar Pine, who defended the city from a pack of Sabyrs. Marrow and his team caught them by surprise and seized their weapons before leaving them in the custody of the authorities.

In Mantle
He is later seen retelling how he was kicked out of a place at least three times to his team, before the Huntsmen-in-training arrived. Following their release of their quarries, Marrow and the rest of Ace-Ops apologize for the miscommunication, before the students are introduced to Atlas Academy by Penny Polendina.

Geist Hunt
In the mission to the Abandoned SDC Mine, Marrow and Harriet Bree join Team RWBY in the mines. He complains about being signed up as a babysitter, which Harriet deflects by saying that's what she is to him. As Weiss Schnee and Blake Belladonna discuss the Schnee Dust Company, Marrow explains that society in Atlas is set up to put the Faunus in the bottom, and humans are willing participants by not helping. Marrow and the rest of the team encounter a Geist, who flees deeper into the mines, and a swarm of Centinels. He later defeats the Geist in the caves along with the rest of Ace-Ops.

Marrow was present after teams RWBY and JNPR were officially received their Huntsmen licenses, along with Elm Ederne and Vine Zeki, helping the new Huntsmen and Huntresses break into their professional field. Following this, Marrow joined the Ace-Ops and Huntsmen in preparations, where he formed a bond with Jaune Arc. He also aided the teams' training, and went on another mission to the SDC with Blake Belladonna and Yang Xiao Long to help clear the Grimm from the area.

Patrol at Robyn Hill's Pre-Victory Party
Following Jacques Schnee's announcement of having "been forced" to close down non-essential Schnee Dust Company facilities, Marrow and Penny were tasked with making sure the elections for Mantle city council went smoothly, as bodyguards for Robyn Hill. The election party Robyn chose to attend was crashed by Tyrian Callows, who massacred partygoers and framed Penny for murders, putting the blame on Atlas. The Happy Huntresses and survivors attacked Marrow, Ruby, Lie Ren, Nora Valkyrie, and Penny, though Marrow froze them temporarily with his Semblance, his attempts to help being ignored. Marrow and the group left, swearing the attacks weren't being staged by Atlas. Soon after, Creatures of Grimm arrived to attack the city, where Marrow lamented they'd have a long night.

Marrow later attended the dinner at the Schnee Manor in "Cordially Invited", as one of Ironwood's guests. After realizing all other Faunus at the party were waiters rather than guests, Marrow left to go outside with Qrow in frustration, on standby in case Ironwood needed further evidence in defending his seat in council.
