Top 5 Most Terrifying Legendary Pokemon

5. Groudon/Kyogre

Groudon and Kyogre are tied for Number 5 because of their destructive potential. Groudon has the potential to evapourate all water, locking the planet in an eternal drought, while Kyogre can drown all landmasses and cause eternal downpours.

4. Rayquaza

Rayquaza is here for how ungodly powerful it is. It is responsible for keeping Groudon and Kyogre in check, and it can't do that without powerful stats. Rayquaza boasts titanic 150 dual offenses, which should never be taken lightly. However, its mediocre Speed allows it to be outsped by viable threats like Xerneas and Arceus. Mega Rayquaza, however is a very different story. Its already high offenses are boosted to 180, and its 115 base Speed is more favourable than base Rayquaza. But what sets Mega Rayquaza apart from all other legendaries is that it doesn't require a Mega Stone to Mega Evolve. It was so powerful that it was banned from Ubers, which is essentially a banlist for all the overpowered legendaries, and placed in the new tier Anything Goes. It would be higher on the list if not for its role as a saviour. Just be grateful that a beast this powerful is willing to save the world from titanic threats like Groudon and Kyogre.

3. Darkrai

Darkrai has the power to lock people in terrifying nightmares, which makes it one of the most haunting Pokemon of all time. Its powers were unstable and powerful, so it had to isolate itself on an island to prevent anyone from getting nightmares from its abilities. If it's powerful enough that it has to practically exile itself, it's worthy of a spot on this list.

2. Yveltal

Yveltal is terrifying because it's the Death Pokemon. It kills things by...existing, really. When it dies, it absorbs the life force of everything around it so it can return a thousand years later. Not to mention that its design speaks pure death.

1. Giratina

Giratina is the god of antimatter, so of course this thing is menacing. Plus, just look at its design. This is the Pokemon equivalent of Satan, having been banished to the Distortion World for its violent nature. And its cutscene in Platinum is downright terrifying.
