Well, If we're naming optional bosses, Ice queen's gear is really good.Not sure if it’s fair to name Plantera here, since half of all late hardmode content is locked behind it anyways, and the only exceptionally good weapons dropped by Plantera itself are the Seedler, Venus Magnum (only on mobile), and Pygmy Staff (only because of the options it unlocks at the Witch Doctor). Naming bosses like Plantera, Golem, Skeletron, and the Wall of Flesh might be unfair here, because not only are they helpful towards progression, they’re mandatory for progression.
Among optional bosses, I’d say that Queen Bee and Duke Fishron offer the strongest equipment for pre-hardmode and hardmode, respectively. Martian Saucer and Hallowed/Corrupt/Crimson Mimic (kind of like a boss?) come in at a close third...

I would have named the final tier of the Old One’s Army among my top choices, except it doesn’t technically require you to beat a boss. Valhalla Knight Armor really is that good.
As stated before, Skeletron, WoF, Plantera and Golem is pretty much very important. (Skeletron - Dungeon, WoF - HM, Plantera - Crap ton of stuff, also Golem, Golem - Lunatic Cultist)
I'd say EoW/BoC for pre-HM because of the helpful armor in their tier (Shadow Armor and Crimson Armor, which might be irreplaceable until Molten).
For HM, Duke Fishron can give you OP stuff before the Pillars (Flairon - Melee, Bubble Gun - Mage, Tsunami - Ranged). Pumpking can give you the Horseman's Blade. Ice Queen for the Blizzard Staff. Don't forget the Cosmic Car Key from the Saucer.
I think that Razorblade is a lot stronger than Bubble Gun since it homes, pierces and has much better range.For HM, Duke Fishron can give you OP stuff before the Pillars (Flairon - Melee, Bubble Gun - Mage, Tsunami - Ranged).
What do you mean by that?The twins
I mean, souls of sight can craft a ton of useful things

Skeletron is optional on mobile/old console/3ds
The old man takes spawn priority over the cultists, so the cultists won’t spawn until Skeletron is defeated. Since the lunar events aren’t on Mobile, 3ds, and old gen consoles, killing Skeletron isn’t required.Skeletron is always optional, is it not?
You don't NEED anything from the dungeon to play the rest of the game. It might even be a certain Challenge, since you can't get a Cobalt, and therefore, Obsidian, or Ankh Shield, or a Shadow Key, so no Underworld Shadow Chest loot either. AFAIK, The game would still be possible to beat, just fairly annoying. So "No Dungeon Loot ever" could be a Terraria playthrough challenge. (you also would be unable to get Pally Hammers or Hardmode Dungeon Caster weapons, or Ectoplasm.... I suppose that means no Pumpkin/Frost moon either, not that you could beat them without Lunar Event items, or Dungeon Weapons, and by the time you get to the Lunar Events, they're useless. Also, no Biome Chests.... Interesting.)
It doesn't even seem to really affect the Cultists and the Sigil to spawn the Lunatic Cultist and start the Lunar Events, nothing about it says "Skeletron must be Defeated" for it to work. (I've never tried this though.)

As for my answer, I think the question is unfair. As has been pointed out already, most of the bosses in the game are important. I'd say Fishron, since he drops amazing items.

The wiki isn’t an official source of information on Terraria, since anybody can edit it.Have you confirmed that? The wiki fails to mention that on Skeletron's page, the Old Man's page, the Lunatic Cultist's page, the Cultists page, or the Mysterious Tablet's page. If you have confirmed it, tModLoader and Mod free, the Wiki ought to be updated with this information.
It's still pretty good. There are Moderators that check to make sure they aren't trolled, and add "Citation Needed" tags if a statement has yet to be proved, and has reference sources sometimes.The wiki isn’t an official source of information on Terraria, since anybody can edit it.
