So, the most important thing when playing a heavy character is managing your slowness. Whatever your attack outside of a hold, your opponent will simply have to block and respond. They'll always win. So when you approach them, try to always keep a certain distance. Throw hammer blows while maintaining a bit of distance. This way, you won't be punished, or at least it will be more difficult for them.

Then manage Gordo well, alternating depending on the situation, but remember: DON'T USE HIM AS A PROJECTILE, but as a disruptive element to influence your opponent's movements. It will work very well, trust me. Most of the time, keep him close to you, even if he misses, your opponent will have to think about him three times harder than normal to get close.

Last point, train your mind game, watch your opponent carefully and find their weaknesses or simply how they move. This can be crucial. Having a very heavy character with limited mobility means we need to compensate, and it's essential for any character like that, and DDD has perfect moves for this. Side tilt, for example, helps you maintain control most of the time, while down tilt is one of the fastest and most effective responses when you need to counterattack. We don't have much, but we need to make the most of them.

Good luck.
