Bang (Metroid)

It grows as it gets shot, until finally it fires a charged blast at Samus before the bubble bursts, revealing the red core, its weak spot. It can also "possess" other enemies, but what exactly this entails is unclear. It bears a resemblance to Metroid Prime's nucleus. It also resembles the Phaazoid species and the Yameba, the latter possibly being an infected and/or X-mimicked version of the Bang.
