Street Fighter X Tekken/M Bison
From Shoryuken Wiki, Marvel vs. Capcom 3 Strategy and More!
In a nutshell
Bison remains similar to his SF4 counterpart - he is a well-rounded character with safe approaches, good footsies, and powerful offensive tools. The new systems implemented in Street Fighter X Tekken arguably make him stronger, allowing him to turn an ordinary Scissor Kick combo into a juggle, which can lead into potentially large damage via a Super, a Cross Art, or even Launching/Tag Canceling with your partner to continue. Bison can fit both the point and anchor role on a team quite well, but keep in mind that this is a tag team game. While it is possible for Bison to OCV, it is not recommended, and at some point you will need to switch out. This actually adds to the list of Bison's weaknesses because you are abruptly stopping your offense, which could lead to a serious mistake.
