Summer Rose

Summer Rose is Ruby Rose's deceased mother. Her gravestone is an altar in the Cliffside Forest.

As revealed in "Burning the Candle", Yang Xiao Long is Ruby's half-sister, making Summer her stepmother. Summer is believed to have died prior to the start of the series, possibly during her final mission.

According to Yang, Summer was a highly skilled Huntress. Yang also reveals that she was part of Team STRQ alongside Taiyang Xiao Long, Raven Branwen and Qrow Branwen. Yang describes Summer as a "Super-Mom" and still fondly remembers her cookies.

Appearance
Summer almost appears to be the spitting image of Ruby, having the same silver eyes, pale complexion, and black and red hair as well.

In her younger days with her team, she appears to be dressed in a white hooded cloak and a skirt, much like her daughter's style. In comparison to the rest of her old team, she appeared to be the shortest.

Personality
Yang described Summer at best as an attentive mother to both her and Ruby. Despite Yang acknowledging that she wasn't Summer's biological daughter, she seemed to have a profound love for her as she cared for Yang like her own.

Abilities and Powers
Summer was a skilled Huntress, going on missions up unto her death. In addition to being a "Super-Mom", Summer is described as a "slayer of giant monsters" by Yang.

Silver Eyes
Summer, and by extension her daughter Ruby, come from a line of warriors who possess powerful abilities related to their silver eyes. The extent of their power is unknown, but according to an ancient legend, those with silver eyes were destined to be warriors, and the Grimm feared them.
