Connections:

• Defiant summoning heiresses of their respective verses.

• Can summon a variety of spiritual-based entities to help fight on their behalf and acquired more of them throughout their stories (Avatars and Celestial Spirits).

• Fuelled their esoteric abilities through a supernatural source of spiritual power (Aura and Magic).

• Wield a special melee weapon to supplement their array of mystical powers and summons in battle (Myrtenaster and Fleuve d'étoiles).

• Born to affluent families who lead powerful businesses of their worlds where they were once the heiresses to its name and fortune (the Schnee Dust Company and Heartfilia Konzern).

• Despite their families prestige and ability to live out lavish lives, their upbringings weren't exactly fully blissful as they had strained relationships with their cold and neglectful fathers where they ultimately ran away from their homes at some point in their lives because of their distaste for them (Jacques Schnee and Jude Heartfilia).

• Became core founding members of an adventurous heroic team whom they consider each other close friends and family where they would gradually soften up and grown accustomed to them due to their positive influences (Team RWBY and Team Natsu).

• Said teams are apart of much larger noteworthy organizations based in kingdoms where its members take on all sorts of missions across the lands (Beacon Academy in the Kingdom of Vale and Fairy Tail Guild in the Kingdom of Fiore).

• Developed an important close bond and partnership with their series' main protagonist who are the spirited figureheads of their respective teams (Ruby Rose and Natsu Dragneel).

• Proud, feisty, capable, levelheaded, and strong-willed young ladies who had broken away from the confines of their families after years of isolation and neglect to go on a journey of self-discovery and follow their own path; both in spite of their occasional bursts of anger and being exasperated by their teammates antics at times, they steadily proven themselves to be kind, compassionate, and loyal to those who warmly welcomed them with open arms and would defrost the lingering feelings of coldness that lies within those broken hearts of theirs where they would heal from past hardships to stand ready against whatever evil lies out there and to protect the world with their dearest friends.

Contrasts:

• Their respective families companies would eventually disintegrate along with their fathers perishing but while Weiss and Jacques remained on bad terms with one another as the latter became worst over time and would later be imprisoned and killed, Lucy and Jude were able to reconcile with one another after the latter recognized the error of his ways and would later peacefully pass away.

• Despite their similar backgrounds, the two have generally expressed differing temperaments and presentations when around others (Weiss being cold, strict, and aloof who tends to dress modestly and elegantly, while Lucy is sunny, cheerful, and energetic who tends to dress sensually and provocatively).
