You aced the "Generic" show of anime.
One word, "Generic".
I don't mean this in a bad way, it was already expected by reading your description this is going to be a satire type where you stereotype some of the "generic" forms of any anime show that happens to air.
And you did it perfectly.
The execution of the beginning was really well done, it looked professional and I thought to myself "With animation like this, this could actually be aired on T.V as a spoof show."
As with the whole plot and storyline of this episode, I just had to laugh at the parts when they tried so hard to say the Japanese phrases right, when it comes to saying their names with "insert name here"-chan, kun, and so on.
Also, the other words that were long and how to pronounce in a way was another plus in terms of humor. It was intentional, I know, and it was good. Because I know this wasn't meant to be taken seriously.
When it comes to the characters, I just liked them all, especially the character where he was powering up, people referred this to be a DBZ reference, but I don't think so, so many shows do this where it drags on a lot, especially the fighting, and ESPECIALLY when it comes to filler episodes as well.
The colors and everything were varied, it showed a lot of strength towards the overall feel of it and this greatly made another plus for me.
The length was really good, I couldn't really tell as I thought I was actually watching a episode of itself. Maybe I just lost track in time.
Overall, I enjoyed it, it was a good watch and I laughed at all the humor when referring to the "Generic" anime that we see today.
Nice job yet again.
