It was suggested I make more of these how strong was X Protag at the start of their series based on others of my favorite series and I agreed with the idea. The next one I decided to do was Danny Phantom and Danny's early scaling is a bit harder then early Usagi's scaling as Danny Phantom is implied to train off screen and gets vaguely stronger, so we don't really know how what feats are applicable to him this early on. This is compounded by the fact that Danny's powers do rise and fall based on his will and emotional state going from losing heavily to the Fright Knight to outright overpowering him mid sword swing. However even as of Episode 1 he should scale to some of the more basic ghost feats.
Ghosts in Danny Phantoms have their own realms including someone like Sydney Poindexter who's realm included a school building. These realms seem shaped to the Ghosts nature with Sydney's being an old timey school and is suggested by outside sources as being shaped by them. Given their school is large enough that "200 yards" is considered easily within the school's bounds, this would pretty easily put this at a city block level feat that even Episode 1 Danny should scale to as Sydney is not considered strong at all by ghost standards it seems. This is somewhat consistent as in the first episode Danny hits the Lunch Lady Meat Monster, a large building sized monster with enough force to crater the ground calced at 737 tons of TNT or Multi-City Block Level though the force is enough to make him tremble as he crawls out of the crater. There's an argument he should be stronger based on downscaling from later feats, in particular that Skulker's realm is an entire island and Skulker is actually a small weak ghost inside a power armor suit, though as his suit is ectoplasmic, it could be argued that it is part of him?
Speedwise, Danny even in this early section of the story is likely relativistic in speeds downscaling from later FTL feats like the Spectre Speeder traveling from Saturn to Earth comfortably within a day and Vlad Plasmius thinking he could become a free-floating space nomad. Both are faster by Danny and maybe by hundreds of times or thousands of times for Vlad, but the gap is not likely to be higher then that. Being relativistic is also consistent with other depictions of Ghost Rays being like lasers and moving at lightspeed, as well as the fact that even in Season 1 Danny regularly had to keep up with Johnny 13's shadow which is literally a shadow and plausibly moves at lightspeed.
In terms of abilities, Danny has numerous of his ghost abilities though many are yet to be developed by Episode 1, with him only accepting himself as the protector of Amity Park at the end of the first ep. Still he has access to invisibility, intangibility, and flight as the distinctive ghost powers, though the former two he doesn't seem to have full control over. He can also phase other people or objects invisible or intangible at will as he does to phase a dumpster so the meat falls on Dash.
Danny also shows impressive body malleability stretching his body drastically in his ghost form and would still have ghostly regeneration, enough that his body being splattered into goo would only phase him. He would naturally have resistance to many abilities commonly had by Ghosts as well as a ghost sense.
He would also still have his powerful will that lets him overpower possession attempts and grow stronger in times of determination. How much stronger isn't super important, just that it's vastly beyond his normal tier, though for context, it allowed him to overpower the Fright Knight who was causing a global storm, a country level feat. Some people argue the verse is much higher, but once again, not super relevant for this unless you think Episode 1 No-Training Danny also scales to a cosmic tier. Danny might be able to access his other powers accidentally. In Season 1 he had a tendency to unlock powers basically by accident including his overshadowing and energy projection though without knowledge of them it's unknown if they would apply.
Obviously this Danny's weakness is he has little control of powers, even accidentally de-transforming once mid-combat and has no combat training and little combat experience. While he proved himself capable and a fast thinker befitting of coming from a family of Ghost-Hunters, Danny is still inexperienced with his powers and mostly fights conventionally with some added benefits of his major ghost powers.
So overall Danny in the First Episode is probably multi-city block level with the potential to rise billions of times stronger with likely relativistic speeds, superhuman willpower, regeneration and body malleability, an inconsistent ability to use intangibility, invisibility, and flight, the potential to use a much wider variety of ghost powers he's unaware of, and some more minor abilities such as adhesion and ghost sensing.
Against other Cartoon protags of the time Danny unfortunately wouldn't do very well as at the time it was very common at the time for most cartoon characters to not change that much or get much stronger over their series meaning it would be Episode 1 Danny vs essentially EoS versions. For instance if he fought someone like Episode 1 Spongebob, Timmy Turner, or Jimmy Neutron he'd mostly just be fighting their end of series versions but with less experience. Characters like Aang and Robin from Teen Titans would be more interesting as they're in mostly the same physical range. Robin is similarly fast and a few times more powerful going off several low kiloton level feats in Teen Titans but wouldn't be able to get through Danny's regen assuming he can maintain his ghost form with Danny being able to wear Robin down or if he needs to get tap into his willpower or possession. Danny vs Aang, Aang should have similar or higher attack potency via his bending though Danny should have notably higher physical stats and both can tap into a much higher power level temporarily.
Against the newer cartoons where some of them tend to be more grounded in their stats, and there's a lot more focus on progression, Danny would be a lot more interesting. Vs Luz from TOH for instance, Episode 1 Luz might unironically scale to similar physical levels to Danny based on some city block to town level feats in TOH and light-timing, though Episode 1 Luz has no magic. Similar for someone like Anne from Amphibia. Finn the Human would have more abilities but Episode 1 Danny seems to have substantially higher stats.
Outside of that, Episode 1 Danny would be pretty strong in most non-cartoons going up against start of series versions. Episode 1 Goku and Naruto would absolutely be taken down outside of a chance transformation into Oozaru or Kyuubi Chakra form, though as mentioned Danny can himself access much higher level of power with determination. Episode 1 Yusuke Urameshi is a normal ghost, something Danny is especially suited to beating. Episode 1 Luffy and Ichigo might scale to similar or a bit stronger, but not so much stronger that Danny can't use his superior speed to defeat them. Episode 1 Yugi has hax that can definitely beat Danny, especially if they engage in a game of darkness, but in a conventional fight Danny can probably blitz and hit him. Even some other more powerful Shonen/Seinen series alongside Dragon Ball, things Saint Seiya and Bastard!! while Seiya and Dark Schneider start more powerful then Danny and probably win, they definitely don't start as fast with Danny being possible able to pull a win just from getting very determined. While his power level doesn't look that impressive nowadays, the combination of speed and some honestly pretty potent abilities means that Episode 1 Danny would actually be a bit of a beast in crossverse episode 1 matches.
