!!Tropes across the entire arc:
* AnachronicOrder: This story arc chronologically takes place after the [[Recap/StarWarsTheCloneWarsS2E18TheZilloBeast Zillo]] [[Recap/StarWarsTheCloneWarsS2E19TheZilloBeastStrikesBack Beast arc]].
* EpisodeOfTheDead: The Geonosis Arc turns into one of these as the arc approaches its final hours.
* MarathonLevel: This is easily the longest arc in the entire series, especially when it first came out as most arcs before never went beyond 3 episodes, and the arc itself having a total run time of '''''2 hours''''', just long enough to considered a feature film like the other films of the franchise. The closest we got to another Five-parter are the Four-parters introduced in season 4 and onward.
* WarIsHell: The Geonosis Arc is essentially the Umbara Arc, except with ''Attack Of The Clones'' aesthetics. Which naturally means that lots of clones, droids and Geonosians die, several of the main characters are badly injured or incapacitated, and the raging violence showcases the fury of the Clone Wars, and seeing as this is an ''early'' part of the conflict, it provides a benchmark for how it will only get worse as the series goes on.
