Rospark the Floroid (ローズパーク・ザ・フラワロイド Rōzupāku za Furawaroido, "Rospark the Floweroid" in Japan) is a rose-based Pseudoroid from the Mega Man ZX series who attacks by using electricity. He is a light-weight Pseudoroid designed to fight effectively even on the most difficult terrain.

In regards to personality, Rospark tends to speak in a dramatic manner, using terms related to flowers. His tone of voice is also shown to be somewhat flamboyant and somewhat effeminate, although when doing battle with them it's slightly higher pitched and more tense. His reaction towards the Mega Man Model A varies depending on whether the player is controlling Grey or Ashe. He seems to be elated by Grey's presence, calling him a "handsome boy", but expresses sheer antipathy towards Ashe, claiming at one point that he despises "pesky little girls". He seems to have a similar elation to Gerry the Raider, based on his comments to him while terrorizing him. The Japanese manual and website imply that his mannerisms were the result of faulty circuitry.
