SuperMariaJustine4

SuperMariaJustine4, referred to as Justine for short, is a major character in Slimey & SMJ4. She is Justin's younger sister/female counterpart.

Personality
Justine is usually calm, laid-back and openly friendly towards those who are nice to her. Even though she is a kind person, she does have a tendency to get fussy and sassy when people disrespect her, most notably in a more perverted manner. Justine's favorite hobbies include acrobatics, anime, reality television, cooking, gymnastics and, due to the fact that she is a tomboy, daring events.

SuperMarioJustin4
Justine and Justin are brother and sister. They interact with each other occasionally since they are siblings. Sometimes, Justine gets extremely annoyed by Justin's comedic antics.

Slimey
Slimey and Justine usually don't interact with each other, but they do on more serious occasions.

SMJ4.blend1
Justine doesn't tolerate .blend1 more so than Justin himself. There have been moments when .blend1 tried to sexually harass Justine and even seduce her. But Justine is smart enough not to be fooled by him.

Daughter Hyde
Daughter Hyde started out as the darker side of Justine, but after her first appearance, it was scrapped and became her own character. Unlike SMJ4.blend1 and Justin, Justine and Hyde share a close relationship with each other and almost consider each other best friends. Later, they both confess that they has a love interest with each other, which revealed that they both displayed lesbian behavior. Hyde is very defensive for Justine.

Trivia
Her voice actor is Tara Strong, who is well known for voicing Twilight Sparkle from My Little Pony: Friendship is Magic, Raven from Teen Titans, and many others.
