Mega Lucario beats Pikachu handily, but doesn't stop once Pikachu is down. Its eyes glowing red out of control, and it goes in for another attack, even after Ash shields Pikachu with his body. It's only thanks to the timely intervention of Korrina's grandfather that things don't get truly messy.
Thor could probably take out pikachu with one hammer throw. Pikachu's thunderbolt wouldn't do much but other moves like quick attack might hurt him. Although his health Will probably be in the thousands because he's a God. Pikachu may use double team repeatedly but eventually Thor will get a hit.
3 Ash's Pikachu Has Battled Many Legendary Pokemon
Dragonite, Silvally, Latios, Zeraora, and Regice are some of the most powerful Pokemon Pikachu has come up against, and the fact that he was able to hold his own with each one, and even defeat a few of them, shows just how much power he possesses.
A level 30 Pikachu with 804 CP defeats a level 30 Mewtwo with 3582 CP in this battle simulation. The attacking Pikachu was using Unknown as its quick and Unknown as its special move. The defending Mewtwo was using Unknown as its quick and Unknown as its special move.
Even with Pikachu's perfect design, the Pokémon and Raichu were often contrasted against each other in the Pokémon anime, with Raichu having brute strength at the cost of Pikachu's agility. This is untrue in the games, however, where Pikachu is weaker than Raichu by at least 15 points in every stat.
Arceus is infinitely better. Pikachu is extremely cute and beats Arceus by far in that category. but Arceus is much cooler, and more powerful. Hell, this Pokemon is basically god, and may be the most powerful Pokemon of all time.
Time and time again, Pikachu has proven why he is Ash's strongest Pokemon. Pikachu partnered up with Ash when he first began his journey in the Kanto region, and though the two got off to a rocky start, their bond eventually grew, and they became inseparable.
Pikachu in the Pokémon Adventures manga is depicted as stronger than it is in the anime, able to defeat Onix without special power-ups. Red and his Pikachu develop a strong bond through their gym battle, similar to Ash and Pikachu's relationship in the anime.
In the anime, Arceus is weak to QUICKSILVER, which is used to try to kill him in the past. Ash's Pikachu has ridiculous plot armor, which has made the anime very boring to watch, but realistically, Arceus would wipe out Ash's whole team.
Mew, the original Pokémon from which Mewtwo was cloned, can defeat Mewtwo with its DNA that allows transformation into any living creature. Others like Rayquaza, Ho-Oh, and several other Legendaries have the potential to defeat Mewtwo in battle, but there are still many that are weaker than this powerful Gen 1 Pokémon.
In a fight between Mewtwo and Mew, the winner would be Mew. Both Pokemon have immense power and physical attributes, but Mew emerged victorious since he has far superior intelligence over his clone.
While Mewtwo has the edge in damage output, Mew is no pushover; it simply doesn't perform quite as well as its wicked counterpart. It still has great versatility thanks to its massive pool of learnable moves, but getting the right attacks for a quality moveset is an expensive and time-consuming ordeal for many players.
While the series never outright confirms what makes Pikachu special or rare, it's evident that it is more powerful and different from others of its kind. There is a possibility that Ash's Pikachu is maxed out at level 100 without evolving, explaining its dominance in Pokémon battles.
Nevertheless, there are a few occasions where Pikachu defeats a Legendary and the defeat of Brandon's ferocious Ice-Type Regice is one of the more ridiculous.
Zapdos is much stronger than any version of Pikachu. Zapdos is much stronger than any version of Pikachu. I liked Pikachu a but too, but I also dumped him for Zapdos. It's pretty pathetic when Zapdos can beat Pikachu 1 v 1 when Pikachu hits Zapdos for neutral and Zapdos hits Pikachu for NVE.
Mega rayquaza will easily be victorious over mega mewtwo as rayquaza doesn't require a mega stone to evolve. Which means, it can hold an item too; which mega mewtwo can't. This thing can give a huge benefit to mega rayquaza if you use that benefit in best efficient way.
For the “God of Pokemon” Arceus is significantly weaker in the games, probably because it doesn't have a Mega Evolution and base stats total up to only 600. Also, it's a Normal type and its Plates just aren't as flexible as in the anime. So, Rayquaza will definitely win.
