These are some ideas for a Snorlax crest, which I think thematically fits. All of them together are OP, so please choose only a few :3
Gives Snorlax the ability comatose.
- This lets it spam facade, as well as avoid status moves. I think someone else suggested it as well.
If sleep talk chooses rest, then the HP goes back to full.
- Might be too op. Throwback to gen 2.
Gives Snorlax the effect of the ability harvest.
- GMax Replenish
Moves that seem like it would hit harder with users weight gets powered up.
- eg Body Slam, Heavy Slam, Bulldoze, EQ, High Horsepower, Stomping Tantrum, Steel Roller, Take Down etc
All physical moves have a chance to paralyze the opponent
- EVERYTHING is body slam
Defense Curl increses defense by 2 stages.
Gives some buff to belly drum
- Takes only 1/4 HP, works like Z-belly drum, gives an omniboost etc.
[If anyone else wants to add to the list, please feel free to copy-paste.]
