This is the main problem with G5: so many characters, so few toys of them. It was also an issue with G4, & G3 didn't even make Spike, let alone half the unicorns & a quarter of the pegasi...
Even G1's Tales didn't have every character made. The most common G1 Customs are of Teddy, Lancer, Ace, & Miss Hackney, so what does that tell you???

Because if they did make toys of more characters, they'd fly off the shelves!!!
