For these Meganium raids, trainers will build their team around boosting the firepower of Krookodile before it attacks with Power Trip, which scales in damage as the user raises their stats. This is used in conjunction with the raid supporter Pokemon to give the move enough firepower to take down Meganium in a single strike.

Pokemon	Ability	EV Training Spread	Nature	Held Item	Moveset	Tera Type
Krookodile	Anger Point	252 HP, 252 Atk, 4 Def	Adamant	Choice Band	Power Trip and three other moves of your choosing	Dark
Meowscarada (Level 36)	Protean	252 HP, 252 Spd, 4 Def	Timid	Focus Sash	Flower Trick, Charm, Fake Tears, Mud-Slap	Grass
Stonjourner	Power Spot	252 HP, 252 Sp. Def, 4 Def	Calm	Focus Sash	Any Moves	Rock
Umbreon	Synchronize	252 HP, 252 Sp. Def, 4 Def	Calm	Zoom Lens	Screech, Fake Tears, Light Screen, Snarl	Dark

It should be noted that all Pokemon used in this Meganium 7-star raid will be level 100 except for Meowscarada, which will have to hit Krookodile without killing it to activate its Anger Point ability. It is imperative that Meowscarada is kept upright on the first turn, and Focus Sash should help. Otherwise, Krookodile won't gain the necessary firepower to counter and defeat Meganium in one hit.

Below, you can find the necessary steps to land your OHKO against Meganium raids in Pokemon Scarlet and Violet:

1. Umbreon will use Screech. Zoom Lens ensures this attack will land and lower Meganium's Defense stat.
2. Meowscarada will attack Krookodile with Flower Trick, guaranteeing a critical hit that will trigger Krookodile's Anger Point ability and maximize its Attack stat.
3. Have the player controlling Stonjourner activate an Attack Cheer, multiplying the team's offensive stats by x1.5. Stonjourner's Power Spot ability will also boost the damage of its teammates' moves by 30%, further strengthening Krookodile's Power Trip attack.
4. Lastly, have Krookodile attack Meganium with Power Trip. The resulting move after all of the buffs are accounted for should deal well over 100% of Meganium's health and take it out at the end of the first turn.

Meganium will attack with Zen Headbutt on Turn 1, but it shouldn't be enough to defeat Krookodile or Umbreon, and Meowscarada/Stonjourner have Focus Sash to ensure they survive the attack if they're targeted. If all goes well, Krookodile can OHKO Meganium in this Pokemon Scarlet and Violetraid.

It's incredibly important that players invite trainers into the raid who know and are willing to participate in this strategy down to the last detail, as one mistake can lead to the raid failing.
