Table in need of reconstruction 

The tables looks excessively messed up:

The table takes up far too much scrolling space due to the multiple data fields, esp. the Pony Description.
There are far too many colours and some dark colours make text hard to read.
Minor characters are mixed up with the major characters.

In answer to these problems:

I suggest putting long boxes under each row of pony characteristics for the descriptions, sort of like a standard TV Episode list, the description box being the equivalent of a summary box. That way the description boxes don't stretch the cells downward so much.
For consistency sake, the number of colours need to be reduced. I don't see the point of picking that many. If you're intending to make the colours match the body colour of the ponies, it is not going well since half the colours don't match the respective pony. If you insist on darker colours, make the text white, so that is readable.
If Minor characters have to be shown because they had their own toy as well as animated appearance, I suggest marking the Major characters with some sort of Indication like Italics.

Let us see if this can work out well.
