In-Game Description
"This Big John has been developed with extremely harsh environments in mind. Because of its more sinister appearance, it has been improved to perform even more powerful attacks."
Jade John MSA idle

The Jade John is a playable unit in Metal Slug Attack, first appearing the Extra Ops titled "Green Monster".

A recolored version of Big John, Jade John is built the same way as his original incarnation; through the Miner. It costs slightly more than Big John. It is similar to its original counterpart, shooting missiles at the enemy and launching canisters at enemies near it. As such, it is built near the player's base to launch missiles, as its' short range attack is extremely weak. Jade John has impressive attack range, which can be improved even further with MSA Skill small + 2.

As its special, Jade John reveals a mechanical claw, though it does not fire energy projectiles at the player. Rather, the claw will follow the nearest enemy unit before smashing down to crush them. The claw deals decent damage (two hits) and functions in a manner similar to Yoshino's special; they can block physical projectiles, but will not protect against suicide attacks and lasers. The damage is also only applied as the claw comes crashing down on enemies. Jade John will deploy three claws at a time with MSA Skill small + 4 unlocked.

If Jade John is killed while performing the special, it will still continue - however, it will only use the claws that it managed to bring up before being destroyed.

As such, it is very effective against dealing with back-line units, provided that MSA Skill small + 4 is unlocked, as the remaining two claws will trail will advance ahead of the lead claw (the first enemy unit that it can be applied to). Most of the time, surprise units won't appear in front of your frontline, so the claws won't be distracted as easily, especially if paired with good blockers.

When placed in a deck with the Green Hazmat Soldier, they form the "Green Monster" team, lowering their AP costs by 10%.
