Maxima is not a bad character. But he is 100% bottom tier. In 2k3 even the bottom tier are useful but Maxima has too many bad matchups.
If you have any strategies for beating a good duo, ash or malin etc. please share them because I honestly don't think they exist.
Max relies on chance this year. The only real damage from Max is made from punishing or countering certain moves by the opponent. Once they get wise to that he has nothing. There's simply no good/reliable way to get damage.
You have his offensive wake up game (which is weak compared to other grapplers) and his grab DM. Everything else he has is defensive/counter based.
Maybe he could do well like this if it was a different year but with 2003's incredibly fast, offensive based game it's hard to win with defense alone. Especially when Max is so slow this year. He lacks the high priority pokes, specials, traps that the good turtles of 03 have (daimon, ash, malin, king). And all of them can play offensive when they want to, Max on the other hand can't do that very well.
Now despite all of this trash talk against max he can be played effectively. But only if you realize that the opponent will control the match and not you. You just have to flow with that I guess. Just don't expect to dominate any of the top tier. But keep playing him anyway, he's fun as hell.
