You should see how Marvel and DC does it. If anything we've been doing less if we take into account IDW1's continuity, the original Marvel comics before reGeneration One, and G1 Season 3 (ew Sea Monkeys Aliens). We've always Spoiler "subverted the expectations" of any cosmic entities more than we actually had them . The only series that bring their cosmic pantheon into mainstream I can think of is the Unicron Trilogy, Animated, the Cybertron games, and TFP. Bayformers tried to have both the Quintesson and the Primus and Unicron stories but look how terrible they handled that. I say we should put them in more, and perhaps the new comics and the Knightverse will reintroduce The Guiding Hand/13 Primes.
