Odin himself isn’t a secret indeed, in PSO2JP you can still encounter him in Parallel Area and as a random E-trial in the field.
There is one thing I never figured, and perhaps PSO2 Swiki has the answer but I am just too lazy to search for it.
When you encounter Odin as a random E-trial he actually doesn’t use his default appearance and rather uses a PSO2 made character. Why is that? My theory, I think it’s a similar mechanic to the Time Attack ‘Abduction’ method. Whoever encountered it previous to you, it will steal his/her appearance and uses it against you. I might be wrong and it just uses random characters, but it’s an intriguing thought.
Some several encounters of Odin when it uses PSO2 character made appearances: (My apologies for the low resolution.)
You can on a rare occasion encounter Big Varder /Vardha in the Desert Exploration/Expedition. In 9 years of playing this game I probably met him less than 5 times in this setting. The encounter isn’t a secret but I never figured the reason behind this encounter. Why did Sega made this encounter? The only link I have is that Big Varder /Vardha is a resident of Lilipa and that it’s just a random encounter with no real reason behind it. But if someone knows the real reason, I’ll gladly hear it.
Fun fact. If you encounter this boss whether that’s as boss in the Tundra Expedition/Exploration or just as random E-trial and neither you, your partners, your mag or other mobs attack it, it will actually leave you alone. It will not attack you unless you or aforementioned parties do. This only works with the boss. Not to be confused with the regular Malmoth/Marmoth mobs, they will attack you regardless.
Hidden Lobby Assets
Rather development related than it being a secret. Shortly after each seasonal lobby expires you can occasionally find leftover assets/decoration still lingering around, they’re hidden though and the only way to find them is either with camera mods or get out of bounds with glitching through walls and floors in lobby.
Halloween assets found underneath the shop area several weeks after the lobby had retired:
Boundaries of Expedition/Exploration maps
Again not a secret and more related to the game’s development. If you can get yourself out of bounds in an Expedition/Exploration map, you can view the edges and you figure that the maps are circular rather than squared.
Getting out of bounds in Coast Expedition/Exploration:
Some years ago I started studying the different behaviors of the mobs, I sadly never finished it and stopped before Episode 3 came out and totally forgot about it. But I remembered concluding that Otherwordly/Special enemies (Rare rappies, Tagamikazuchi etc.) are friendly towards other species like Natives/Sylvants, Draconians/Dragonkin, Automata/Mechs & Oceanids. But Falspawn/Darkers however are hostile towards them.
And then Nyau came out and started attacking everything and my research became invalid. Encountered a Nyau attacking a Lilipan, that was a hilarious sight though. It’s rather funny when it cries for help when you defeat it while it would indiscriminately attack everything on sight. That does raise the question on whether Nyau would start attacking its own reinforcements.
Did we ever got a definitive answer to why D’nar/Diniar, Opta and Ria keep crashing their Aircrafts? Is it their skills or the ships being unreliable? Maybe both? Or perhaps something else. I assume it’s nothing to deep.
Perhaps not many know and not all of them are familiar. But the default stock characters of PSO2 actually have names. And in most cases their names refer to characters from older PSO entries.
The poster boy of Phantasy Star Online 2 is named Ash, he shares the name with his Phantasy Star Online counterpart Ash Canaan. (He is also the default HUmar of PSO.)

There are however 2 characters not named after Phantasy Star characters but are named after outfits they wear, an odd couple when it comes to naming conventions.
Not to be confused with the NPC named Saga, he definitely looks like him but he has a slightly different color pattern. This guy is named after the Saihajin outfit.
Named after the outfit she wears, the Fulinka/Hibiki series.
(Forgive me for this one, I am going to use PSO2JP’s naming convention. I worked on this list while playing the JP version. It would be too much work to convert it all to the naming convention of the Global version.)
Around a year ago it struck me that PSO2 is filled with numerous 'Trinities', I assume most of them were intentionally created by Sega but perhaps there are some pure coincidental.
The first trio the game makes you aware of is the Trinity of S-ATK (MEL Power), R-ATK (RNG Power) & T-ATK (TEC Power), which basically serves as the foundation for its gameplay. (Probably the most famous Trinity is the 'Holy Trinity': the Father, the Son and the Holy Spirit. The Trinity: Spirit, Soul & Body derived from that. Personally, I prefer the Holy Trinity of Superman, Batman & Wonder Woman.)
Aside from the ATK (Power) Trinity I wondered if I could find all Trinities the game has, I have listed below the ones I found so far. I only did Gunslash/Gunblade series for weapons because it would be too much work to cover every single weapon type. Some of these might be a hard reach.

PSO2’s Disney Princess:
Also don't take this too serious, it's purely an observation.
We can pretty much confirm that Quna originated from the Kingdom Hearts series, but from which brand of mob?
Is she a Heartless?
Or perhaps an Unversed?
Or maybe a Dream Eater?
Perhaps she is Hikaru Utada, cause she can sing! Nah, I’m joking with this one. But the resemblance is rather funny.
