Ghost powers
Upon receiving his ghost powers in a lab accident involving his parents' Fenton portal, Danny often had great difficulties controlling it.[2] At the mercy to his teenage emotions in the beginning, his nervous behavior would often trigger episodes of intangibility or invisibility, much to his embarrassment.[3] Besides his ability to switch between his human and ghost forms, his early powers composed primary of the most generic of ghostly powers; flight, intangibility, and invisibility. When he transforms, he shouts out "Goin' Ghost", (which Vlad Plasmius calls Danny's "Battle cry"), before two white rings intersect his body. When he flies, his legs often turn into a ghost "tail". He also gains super strength and enhanced abilities and agility his human form does not possess. He can manipulate his body and twist himself into odd shapes to avoid stray attacks.[4][12][31] He is able to walk on walls, though this is rarely utilized.[14]
He has a ghost sense that manifests as a blue wisp from his mouth that announces the presence of nearby ghosts. It is described as being akin to a cold breath during chilly weather[15] and served as a precursor to his ice powers.[32]
Danny gains a ghost ray early on which has become one of his most frequently used powers;[33] becoming an energy ball that can expand in size and corresponding area of effect, and even be usable as a flashlight at low power.[34] He possess a ghost shield that can protect him by deflecting attacks.[7][35] He has the ability to overshadow people and ghosts, causing their eyes to glow green as well as change their voice to his.[3][7][33] He later masters the power, able to cancel or control such obvious signs of possession.[28] He is also capable of entering people's dreams.[36]
One of his most powerful attacks is the Ghostly Wail,[21] a sonic scream that can hit multiple targets. It appears to take massive amounts of energy to utilize, draining Danny heavily, so he often reverts to his human form after use. By the end of the series he appears to have mastered this ability (to an extent).[17] He can duplicate himself, but struggles to master it throughout the series—often with disastrous, or amusing, results.[37][38] He succeeds in splitting in two,[11] then eventually four later on.[20]
Danny is either able to breathe underwater when in ghost form, or likely does not need to breathe.[39] It is unclear if he can breathe in space, though it is shown that he can handle its extreme conditions with little more than a space helmet.[17][19] Danny can also later on produce an ice beam which can freeze the opponent among other things and so on. His ice powers, though, do not come in till later in the series since it takes a while for them to develop.
