Suicidal Overconfidence: Season 1's monsters possibly have more "run right at the Megazord while it's charging its finishing attack" moments than monsters in any other season.On occasion, when a monster is destroyed, we're shown a pile of rocks falling to the ground. Golem: Technically, Finster's monsters are these, as they're all clay sculptures brought to life.
While this would never be gone from the franchise entirely after Mighty Morphin', it becomes significantly less common afterward.
Early Installment Weirdness: Some monsters such as Giant, Mighty Minotaur, Spidertron, and Hatchasaurus dont talk beyond grunts, roars, and laughing.This would be very obvious when the Ultrazord would blast a monster, but the Power Sword's slash would still appear over it before it exploded, and vice-versa. Dies Differently in Adaptation: Some of the Zyu2 monsters were killed in a different way than intended in the original footage.Canon Foreigner: The "Zyu2" monsters, who never appeared in Zyuranger and were created exclusively for Power Rangers.Beastman: While the Zyuranger monsters had a mythology/folklore theme (though this didn't translate into MMPR), the Zyu2 monsters were mostly this shark-man, mantis-man, mole-man, rhino-man, etc.Adapted Out: Averted this is the only season of Power Rangers to include all of its corresponding Sentai's monsters.
