In Pokémon Live!
Throughout Pokémon Live!, MechaMew2 shows no emotion or remorse for having to hurt Pokémon. Giovanni promised Trainers the very rare Diamond Badge to anyone who could defeat it. MechaMew2 is defeated when Mewtwo uses an attack against it which was full of love, care, and friendship. After experiencing these feelings, MechaMew2 decides it can no longer go along with Giovanni's evil plan, and it grabs Giovanni by the throat and performs Selfdestruct, destroying Giovanni's Gym and itself.
The prop is 10' tall, 7' wide, and 8' deep. It was made by Costume Armour. If the weight listed on the TCG card is that of the prop, it weighs 4587 lbs.
MechaMew2 bears a resemblance to Mewtwo when it wore armor in The Battle of the Badge and It's Mr. Mime Time. Instead of legs, MechaMew2 uses tank-like treads to move around, and it carries a large power source on the front of its body.
In the TCG
MechaMew2 never made an official appearance in the Pokémon Trading Card Game; however, a promotional card was given out to attendees of the performance. The card is 7" tall by 5" wide, making it slightly smaller than the jumbo-sized Pokémon cards. The backside of the card features the Pokémon Live! logo, instead of the standard TCG card back; this was likely done to show its non-compatibility with the Trading Card Game.
- Part of its design (namely the treads) resembles the HK-Tanks from the Terminator series.
- Weighing in at 4587 lbs, MechaMew2 is over twice as heavy as Groudon, who is officially known as the heaviest Pokémon in existence.
