Kushina Habanero is ok at S+ but still one of the best S+, I would put Shark Kisame God Tier though.

Itachi Anbu should be S+, he is like Jinpachi, removes debuffs for 2 Uchiha units and gives an extra standard attack. Considering Shisui has arguably the best standard attack in the game that's very good, also Madara hitting dodge units.

He c*so ignite the whole enemy team(4 units) every round with 30 combo, unlike Jinpachi who can ignite for 3 rounds and that's it, only ignites with chase 1 person after that.

He has 3 chases and removes buffs/shield also tags with mystery, which can be better vs immune teams. Jinpachi alone can't do anything against Root of Warrior or Flower Guard.

Imo best God Tier ninjas from first to last are:

1.Shisui (Uchiha teams OP, with Madara, Masked Man, Itachi Susanoo/Anbu, all being very very good for PvP - doesn't immobile chase so you may ditch him for Masked Man if you also have Madara & Itachi Anbu for the clear)

2.Hokage Minato (individually would be one of the strongest here, but there's no scary stand out-ish team for him)

3.Kurama Naruto (very good for pvp)

4.6 Tails Naruto (very good for pvp)

5.Itachi Susanoo (that chaos thingy is very useless vs immune teams, being temporary or permanent, which wasn't the case in the anime, he could chaos anyone there)

6.Edo Hashirama (More Gnw/Bonds oriented)

7.Edo Deidara (More Gnw/Bonds oriented)

8.Hokage Tsunade (More Gnw/Bonds oriented)

Madara Uchiha and Masked Man should also be God Tier. Masked Man for first round remove immunity and double immobile + dodge(you can really ruin someone's second round initiative advantage with him), Madara for shining in Uchiha teams, and being a very good damage dealer with taijutsu/combo immunity, and non removable buff.

*with strong bias towards Minato cause he's the only one I got & Shisui cause I like Uchiha teams

I didn't know Saitama was Lightning-attributed!
