Elysion is a unit original to Metal Slug Attack. Parts can be obtained through her Box Crank.
A cursed pirate, Elysion uses the Monoeyes' curse against them. As her normal attack, she uses her tentacle arm to summon 12 jellyfish at her enemies. These jellyfish home in on the nearest target, but move rather slowly.
As her special, she summons a single kraken at her enemies. She can summon two additional krakens with 4. These krakens can cover the whole map, but will stop upon running into an enemy ground unit or blocker. They are also capable of absorbing physical projectiles such as bullets without harm.
Initially, Elysion seems lackluster given her attacks' low damage. However, the krakens deal rapid amounts of damage, which can easily stack and kill reasonably bulky units. Elysion lacks incendiary resistance, so she should avoid units like the Metal Rear EX or Dragon Nosuke+, which has a powerful incendiary attack.
Elysion is best used with a strong pusher, so that the enemy does not have enough time to setup a proper defense against her. As such, she's best to be used with someone like Towa or Nova. The "Reload" option is highly recommended when using Elysion, as her standard attacks are too weak to help the player.
The best counters against Elysion are to use blockers. A list of blockers from best to worst are as follows (assume Elysion has unlocked skill 4, which means three krakens):
|Dark Monoeye||With protection, monoliths last long enough to completely block special. Unfortunately, it cannot stop Elysion if she is enhanced by Rumi or Sisilia unless when stacked.|
|ShootingRay||Can block all three krakens (and survive) - however, requires timing in advance, as there is a short delay before it gets into position. Additionally, its suicide attack deals moderate damage against her.|
|Jade John||Only if enhanced - will not work otherwise. Requires timing in advance.|
|Esther||Grandee lasts long enough to block special, though can require timing.|
|Lovely Mummy||Requires precise timing, as krakens that get past the summoned mummy will collide into the nearest unit.|
|Midori||Only if enhanced - will not work otherwise. Requires precise timing due to how "TETSUJIN KUN" works, as the short retreat it performs can cause a kraken to slip by.|
|Everlasting Summer Abigail||Laser reflectors can block krakens; however, it is removed in the process - requires stacks. Also requires good timing or reflectors will ignore krakens.|
|Red Goblin||Only if enhanced - will not work otherwise. Requires precise timing and protection due to his low health.|
|Licht||Requires precise timing as there is a short delay before he performs his bullet-cancelling projectiles and also due to its short range.|
|50||52500||57750||63525||69877||76865||* HP might be increased by skills / items or buffs|
- If 4 has not been unlocked yet, Elysion will yell "Kraken" at the end of the attack. If 4 has been unlocked, she will yell "Burn them!" instead.
