The user hits the target with its tail. This may also poison the target. Critical hits land more easily.

Eternatus VMAX has the Ability “Eternal Zone”. This Ability starts working as soon as Eternatus VMAX hits the field so long as you meet its condition: you must not have any non-Darkness Pokémon in play. Assuming that is the case, you are now allowed to have up to 8 Pokémon on your Bench, but they must all still be Darkness types. In fact, once Eternal Zone is in effect, you cannot put any non-Darkness Pokémon into play; not from your hand, and not even through effects that play them from elsewhere! If Eternal Zone stops working, you have to discard Pokémon from your Bench until you have no more than five Pokémon on your Bench. The user strikes everything around it by swamping the area with a giant sludge wave. This may also poison those hit. The user goes to sleep for two turns. This fully restores the user's HP and heals any status conditions. Infinite amounts of energy pour from this Pokémon's enlarged core, warping the surrounding space-time.The user drenches the target in a special poisonous liquid. This move's power is doubled if the target is poisoned. The target is stabbed with a tentacle, arm, or the like steeped in poison. This may also poison the target.

It was inside a meteorite that fell 20,000 years ago. There seems to be a connection between this Pokémon and the Dynamax phenomenon. Note: Unless otherwise stated, assume that this review refers to the 2021 (TEU-On) Standard Format or 2021 (…still BW-On) Expanded Format. As a result of Rose's meddling, Eternatus absorbed all the energy in the Galar region. It's now in a state of power overload. The user creates a substitute for itself using some of its HP. The substitute serves as the user's decoy. Eternatus has an alternate form used in its initial capture battle. This form is not usable natively in the games at this time but its appearance is used in the animation for the move EternabeamThe core on its chest absorbs energy emanating from the lands of the Galar region. This energy is what allows Eternatus to stay active.

The user lays a trap of poison spikes at the feet of the opposing team. The spikes will poison opposing Pokémon that switch into battle. VMAX is also the card’s Stage, and except where an effect specifically cites being a Stage 1 or being a VMAX, they’re functionally the same. Of course, that is still a big distinction; general Evolution support works for Eternatus VMAX, but not Stage 1 support. Eternatus VMAX is a Darkness type Pokémon, and that’s very good right now. As of the Sword & Shield series, now VG Ghost and Psychic types – both represented as Psychic types in the TCG – are usually [D] Weak. There also are no new [D] Resistant Pokémon being released, now that the Fairy type has been merged into the TCG Psychic type. You may still encounter it in Expanded, or on the remaining SM-era Fairy types that are still Standard-legal. The Darkness type enjoys good support in both Standard and Expanded, but we’ll detail that later. The user gathers all its light energy and releases it all at once. This may also lower the target's Sp. Def stat.I believe Eternatus VMAX will become another one of the archetypes that the format would watch out for, as well as Charizard VMAX. Maybe if there was a Darkness type Pokemon that can boost damage output, then Eternatus can finally reach OHKO levels.
