I think we saw all 3 types of sage modes in Naruto series

[Sagebee]

We have clear confirmation of both toad and snake sage mode

I think it's retarded for hashis sage mode to be other than slug sage mode

And it's my own personal hunch but I think all 3 rsm users in Naruto used all 3 types

Naruto with toads

My hunch obito with snakes since you need sage mode to use rsm and there's hints in his juubi mode that he was using snake sage mode

And madara with slugs from hashi

I agree. RSM would be the planet's natural energy as a whole if we go by the Jyubi, it would reflect/include a fusion of all 3 within it. As for needing SM to gain RSM I disagree as it can be handed directly by Hogaromo all you need is the ability to adapt to it.

While I like your thinking I have to disagree with there only being 3.

When we start looking at the different animals capable of jutsu in the series.

Frogs
Snakes
Cats
Dogs

All have special entities that can talk and perform jutsu.

To me I think each animal type can potentially have its own sage mode. almost like "Affinities"

I think u do need sm for rsm or it at least helps.
When obito absorbed the juubi,he didn't have sage mode and had a harder time controlling the juubi
it wasn't until he controlled the juubi that he gained rsm.

Madara made sure to get hashis sage mode before he absorbed the juubi and had rsm without fighting for control like obito

Naruto still has toad sage mode eyes in rsm minus the coloring around the eyes

I doubt it as it's not listed as a condition for the attainment of RSM. As for Obito having teoible he was being overwhelmed by it's will power. He was still generating the RSM TSB tools prior to that.

Madara gained Hashi's SM initially to be removed from the battelfield however, then he lost his eyeballs and I suppose he needed it until re retrieved his eye.

Naruto still had the toad markings because his was Pseudo sage Mode he never possessed the mezo husk. He couldn't fuse the chakras and likely required SM as a mechanism.

Obito had the markings and was using tsbs but they didn't nullify jutsu.he used it on edo hiruzen and hiruzen healed back.
After he controlled the juubi,he got the floating tsb,sun staff and the tomoe necklace on his chest.characteristics of rsm

While obito was the jin,madara told hashi "I'm gonna need another chunk of you"
Getting hashis sage mode was part of madaras plan to "switch"with obito and be the juubis jin.
He didn't need to fight the juubis willpower for full rsm like obito.

This is partially right, the reason Obito wasn't able to nullify Hiruzen was because the TSB user must use the jutsu. Mindless Obito wasn't in any position to use nullification.

While obito was the jin,madara told hashi "I'm gonna need another chunk of you"

That's partially right he intended to use it until he regained his eyes, Madara single Handedly Solod the 9 tailed beasts and 2 perfect Jin + low Jonin level Gaara. He then remade the Jyubi and became it's Jin. He's on another level, he's not Obito who could barely contain one of Madara's eyes why would he struggle?

There is only one sage mode with infinite ways of acquiring it. I would like to see lightning sage mode and Uchiha Sage hype.
