Power Rangers Zeo/Fridge

Fridge Brilliance

 * I took a while to realize the meaning of the line "Rangers at the core" in the Power Rangers ZEO theme song - I thought it might have something to do with the Rangers in the cockpit of the Megazord, or perhaps them being inside their suits, but eventually I realized that what it actually meant was that even though the Rangers had different powers and equipment, they were, at the core, still the same Rangers continuing their fight against evil in the tradition they'd followed in the Mighty Morphin' series.
 * "Mondo's Last Stand" featured Rocky displaying an inferiority complex. Whilst it never got brought up again in Zeo, this would eventually lead to Rocky's Game-Breaking Injury in Turbo: A Power Rangers Movie.
 * Tommy's sudden boost in intelligence and memory skills (as seen In Dino Thunder) may be due to Prince Gasket messing around with Tommy's brain in "King for a Day."
 * Rita being pregnant with their child by the events of the season finale as per Word of God explains quite nicely why she and Zedd left at the end of the season, rather than resume conquering -- they were taking time off to raise their son.
 * If one really thinks about it, the Zeo Rangers as described in the series canon are, literally, the most powerful rangers of all time. The Zeo Crystal was an infinitely self-strengthening power source that would never stop growing more potent. The Zeo Ranger arsenal of weapons and zords was growing more complex and varied with every major episode. But this leads to a serious question that was never answered in any way. Why did they stop using the Zeo powers and move to the Turbo powers? Tommy at the least clearly retains the Red Zeonizer all the way up to Forever Red and it's unlikely he got rid of it afterword, unless that was the base he used to develop the Dino Gems. But that also begs the question of "Why mess with the Zeo Crystal and turn it into something clearly less powerful?" The only answer that logically comes to mind is that the Zeo Crystal is not as much of a penalty free power source as first believed. As we see with season team-ups and was Lampshaded in Power Rangers RPM, morphing tends to cause explosions. Imagine what Zeo morphing would eventually do. That's right, the Zeo powers were pocket supernovas waiting to happen.
 * Keep in mind that these crystals were split from one single crystal... Imagine the power that would cause if they were still united.
