These monsters are too good for the SS tier, so they get their own special tier. By far the best monsters in the entire game.
Restricted to the best of the best. These Mythic monsters are very good but cut just short of OP rank for having either lower stats or just weaker moves compared to OP rank. Despite that, they're easily some of the best in the game, and a team should really consider having any of them.
Restricted to monsters rivaling the ones in SS rank only to have lost due to either worse moves, worse stats, or a worse trait.
Restricted to monsters that perform great or at least good in the competitive scene. The ideal monsters you should tend to go for if you aren't able to obtain higher-rank monsters.
Restricted to monsters with average performance in the Monster Legends meta, due to average stats or situational moves. But they still are considered as viable options for your team.
Restricted to monsters with some flaws in the current meta, but can still perform well on some occasions.
Restricted to monsters that are better than E rank due to better moves and/or stats, but cut short of C rank. Almost never use them, they aren't worth much of your time in the competitive scene.
Restricted to monsters that are so weak, that they could never be in the meta. Only consider using these if you don't have other Mythic monsters.
Restricted to monsters that can be outclassed by Legendaries. You may want to get these monsters, but not use them in the Arena.
