"Ash and Pikachu have been friends since the beginning of the series. They can't be separated or else there would be no point!" they said. So was Brock and Misty until they left. ;>
But besides the joke, I also agree that Ash and Pikachu should always be together and having only Ash would be kind of awkward and unappealing.
Haha thats true, problem is Misty was a good character but due to her lack of an actual 'goal' and the 'Togepi Effect' her longevity was greatly compromised. Brock was lucky as he had a role as the father figure/ carer for the group and lasted a lot longer. Debatable whether his character ran its course or not though.
He should cuz then Ash would be forced to use his damn pokemon but it will never happen lol.
Pikachu was a Pokemon, though.
I wish, but Ash will never Oak Pikachu.
And more to your point, the only thing leaving Pikachu behind would accomplish is giving that particular Pokemon less screen time. The actual problems that you want fixed isn't solvable just by storing away a single Pokemon. For good or for ill, the writers on this show usually focus on specific Pokemon belonging to the characters. If Satoshi left Pikachu behind, they'd choose one of his new Pokemon to take most of the spotlight, just as they did with Mijumaru.
Meloetta arc) To lose GYM battles?
I like Pikachu. But not BW Pikachu. He played the role of a mere cute pet during most of the time in this current series.
I guess I'm part of the minority who actually LIKED when he had more important competitive battles and won with absurd strategies and impossible power. He won't evolve. So the least he should do is be special.
With that said, I want Pikachu to be around so long as Satoshi is around. I like their friendship. I just want a Pikachu that does more cool moves mid-battle like in the previous 4 series...
JOIN THE TOAD SIDE
AND MAY THE BLUE FORCE BE WITH YOU
AND I AM NOT YOUR FATHER!
I can't picture Ash without Pikachu. They're best friends and the show has pointed out again and again how strong their bond is. It wouldn't make sense for Ash to leave Pikachu behind.
I don't want him to leave Pikachu behind, so if Ash could bring both Pikachu and Gible, that would great! Seeing Ash train Gible all the way into Garchomp and then be able to use a mega stone for battles would really be something to look forward to.
Don't forget though guys, Satoshi did remove Pikachu from his Party and gave him to Okido during the Johto League...
