It appears to have poorly-drawn versions of the Peashooter, Sunflower, and an unknown plant from the tower defense titles on the side of its ship with red Xs drawn over them.
However, the Peashooter and Sunflower drawings could represent the Pea Cannon and Heal Flower, respectively.
It does not have a real spawning animation. Instead of popping out of the ground, it suddenly materializes out of nowhere.
However, it does have animations for being Gooped, swallowed from both sides by Chomper, and being eaten by Burrow.
If the player is on a rooftop and the Future Imp is running towards them, the Future Imp will stop when it is close to where the player would be on the ground, and then it will use its Self-Destruct, not damaging the player and vanquishing itself.
When it jumps, its legs retract into it and pop back out when it has landed.
It falls very slowly, as if it is using moon gravity.
It has a variety of unique sounds, although it uses sound effects from both the Mech Gargantuar and the Imp.
The Future Imp can be seen on a poster in the Portal Room for the Imp class (containing Steve) that says "No Mission is Impossible!" next to a Z-Mech, a bunch of Imps, and a Imp piloting the unknown flying machine seen in the Garden Warfare 2 reveal trailer.
