Several types of vegetation appear throughout the Metroid series.
Vegetation is first seen in Metroid II: Return of Samus. The game features two noteworthy types of hazardous vegetation. Bushes, which reappear as red plants in Metroid: Samus Returns, are briar-like constructs found in the depths of Phase 2 and Phase 3. Another type of vegetation, identified as poisonous plants in Nintendo Power walkthroughs, appears as thorny fern-like bushes found in the subterranean tunnels of Phase 4. Both types of vegetation may be cleared with Samus Aran's beam weaponry; however, in the remake, red plants can only be safely bypassed with Lightning Armor.
Barnacles, an obstacle similar to bushes, appear in Tourian in Super Metroid, in the barren wasteland-like area of Tourian where the Big Metroid is encountered. They do not damage Samus, but merely block her path, yet can easily be removed with weapon fire. Super Metroid Nintendo Player's Guide states that it "... may have been secreted by some vile life form, but it's not really clear why it exists." Because of this, it is possible that this substance is some sort of material excreted by Metroids, as it resembles the Metroid webs seen in Phase 4.
A type of overgrowth simply referred to as "vegetation" appears in Metroid Fusion. It appears in the foreground and background and will not harm Samus, and in return she cannot directly destroy it. However, it is the result of overgrowth in the Reactor Silo, and will disappear once Nettori is destroyed.
Nintendo Power issue 31Edit
"The bushes are loaded with damaging thorns. Blast them with your beam if they get in the way and you'll weed whack 'em. The liquid can't be blasted."
Nintendo Power issue 37Edit
"Not only will you meet up with more Metroids than ever before, but you'll also experience long, vertical tunnels with poisonous plants, restraining Metroid webs, and very few platforms."
Super Metroid Nintendo Player's GuideEdit
At point A, and beyond point A, you will encounter areas that are encrusted with an extremely odd barnacle-like material. The substance may have been secreted by some vile life form, but it's not really clear why it exists. To clear a path and get through it, just blast it."
ADAM: Save Rooms and Recharge Rooms are now back online, but with only auxiliary power, no elevators or hatches will work. Without the main silo online, we're still stuck. I believe the source of the problem is the vegetation you saw earlier choking the Reactor Core components. Is your objective clear? Yes No
We'll have to find the source of those roots to proceed.
