Leona is a reticent individual who has trouble expressing herself outside of combat or a mission. Due to her past, she often keeps her emotions in check as she is afraid of losing control and hurting her friends because of her Orochi blood.
Aside from Ralf, Whip, Clark and Commander Heidern, Leona does not talk to anyone. She often feels lonely, but is comforted with the new family she has found with the Ikari mercenaries. Ever since the attempted suicide, Leona resolves to take control of her own Orochi blood, using it only when the situation calls for it, something that she tells her opponents in her own pre-fight dialogues.
She shares several moves with her adoptive father, Heidern, and she also seems to emulate Ralf’s moves. For example; her CD/Blowback attack is almost akin to Ralf’s. Also as the games progress, her moves seem to become more explosive much like Ralf’s and her style of running changing from being like Heidern’s to like Ralf’s, but at the same time still maintaining her more agile techniques taught by Heidern; unlike Heidern however, she has more apparent differences in her techniques via extra variations that focus more on speed and acrobatics.
Being the daughter of Gaidel, she utilizes some slashing claw-like moves later refined by her adoptive father’s fighting style. However, she does not possess power over water like her father does, possibly due to her prior trauma stunting her abilities for a time.
The V-shaped slashmarks that appear at the end of her V-Slasher DM and SDM are an homage to Choudenji Machine Voltes V—the titular giant robot had an attack in which it made a V-shaped slash through the enemy, leaving a glowing V for a few dramatic moments before it is destroyed.
Her Rebel Spark Desperation Move and Super Desperation Move where she plants an explosive on her opponent then moving away from the opponent while making a pose, is actually a homage to Kamen Rider Black RX—a Japanese tokusatsu show where the hero impaled his enemy with his sword, Revolcane, and proceed to do the same pose as sparks came out from his opponent’s belly and eventually exploded.
Also, her jumping CD/Blowback attack resembles Kamen Rider Black’s version of the Rider Kick, owing to the sudden, unexplained glow of reddish energy around her foot, and being performed while in the air. Another Sentai homage includes her exploding earrings (Himitsu Sentai Goranger).
