where can i see that ep did it came out?
Firstly, learn some proper grammar.
Secondly, it is against forum rules to post links to such info. You can pm people for info or find it yourself quite easily.
Thirdly, of course the episode has come out, how else could people talk about what happened in it?
Lastly, quoting yourself and adding almost the exact same thing because no one answered your question for a couple of hours is not an attractive posting habit.

On the episode itself, I loved Naetle's shocked and then guilt-ridden expressions when it realized Ash was Pikachu's trainer and friend. The poor thing looked positively adorable with the tears in its eyes and "I hate myself!" expression.
It is like Bulbasaur but at least it battles somewhat differently, and its personality is more aggressive and good natured rather than Bulbasaur's wise toughness. I do think its funny how it is willing to beat up pokemon to get them to accept its help. Its a good deal more hyper and careless than Ash's Bulbasaur so I think its a good enough difference.
I found the Linoone to be incredibly random. Just what on earth beat it up so badly? It did look neat though seeing Ash and Brock holding it, given how used I am to seeing them hold only small pokemon.
