Having 5 opponents is not just adding stats it is giving the possibility for attack angles, support to each other and distractions. Fujitora and green bull have great ranged attacks that shanks would be able to overcome but now add Laws ability to change his position in the room and it is way harder. Law can just run in front of a meteor and change positions with Shanks to have his face in a meteor. Or put him right into a combo attack of Zoro and King. Zoro has the ability to hurt Kaido and king shouldn’t be much behind. Would either be able to challenge shanks on their own? Of course not but they are not on 1 on 1s. Those 5 have nice synergy’s and in my opinion that would be too much for shanks even though he is likely the endboss of OP.
Table 1: Snake. He can just stare the other players off the table.
Table 2: Prince. He can basically watch every hand played and travel back in time to win the easy way.
Table 3: Yeah telepathy beats shape-shifting.
Table 4: Hardest to judge for me since i am no expert on Bayonetta or Link and if the have some hax but the other three are basically the incarnation of a pokerface. Cloud has exactly one look but is pretty stupid and Raiden is less prone to use dirty tricks compared to Dante. So minus the players that i don´t know about i give it to Dante.
For the winners table there will never be a winner. Snake and Dante are screwed and Kerrigan will read Princes mind to gain the advantage and every time she wins he resets it for him....endless loop of boredom.
BB was fighting Thragg on pretty even footing for days with incredible brutality and receiving wounds that would drop almost any Marvel/DC hero/villain. Thragg being the strongest viltrumite is pretty high tier so i see him and Invincible having a good shot at winning.
