Lenna has various magical abilities from her game and has added effects when in EX Mode. However, aside from that, EX Mode doesn't offer much.
A small hammer comes out of nowhere and hits the enemy. Doublecasts with the effects and graphics of Bartz's Goblin Punch. (Goblin Punch)
Bubbles shoot out of the user to the enemy. Doublecasts with streams of sand towards the enemy. (Desert Storm)
Attacks with bare fists quickly. Doublecasts with Haste, but Haste, a spell used to go faster, goes first. Starts Chase Sequence, which only attacks with bare fists.
A bunch of lightning bolts strike the enemy. Doublecasts with Float, a spell used to make the user last longer in the air. This could be used to execute Thundaga again or use an Aerial HP move.
A ball of fire appears on the enemy, then small explosions occur. Doublecasts with three cone-shaped shards of ice hitting the enemy (Blizzaga). Blizzaga is an HP attack.
Bubbles shoot out of the user to the enemy. Doublecasts with spinning air particles towards the enemy. (Wind Slash)
A number of orbs surround the enemy, later coming together for an attack. Attack cancels if the user is in Chase Sequence before the attack connects. Doublecasts with the Flare spell coming just before the Holy orbs connect.
Calls on Bahamut to attack with a powerful attack with a wide area of effect. The summoning and the attack is really slow. Doublecasts with an attack that speeds up the summoning and the attack. (Speed)
Depletes Brave to heal HP equal to 1/4 of its Brave value, rounded down. Doublecasts with White Wind, which increases the healing by another 1/8. This move takes a while to charge, and if attacked during the healing, the move fails.
A missile comes out of nowhere and slowly homes in to the enemy, dealing HP damage in an explosion. Doublecasts with a line of flames hitting the enemy for Brave damage just before the missile hits. (Flamethrower)
Blue explosions attack in random positions in front of the user. Doublecasts with a vertical beam of energy (Divine Judgement). The Dark Flare does Brave damage in EX Mode.
EX Mode - Job Mastered!
Recovers HP over time during EX Mode.
Gains the ability to use the complete effects of every attack by using a completely different move.
Press SQUARE and CIRCLE repeatedly until Lenna fills up a bar. Either way, Lenna summons the Wind Drake Hiryuu doing a physical attack. If done successfully, Hiryuu turns into Pheonix. Phoenix is much stronger and heals Lenna equal to Curaga's effect.
