Lion Song Zoro: HP: 3558. ATK: 1038. RCV: 32 Rank: 6/10 Special: 25X damage to 1 enemy. Zoro has a TON of Health, but he only has a decent ATK to back that up. Still fairly nice.
Hachi: HP: 986 ATK: 638 RCV: 288 Rank: 2.5/10 Special: 10X damage to all enemies. Compared to the other DEX Slashers, Hachi actually has decent RCV. Not much else though.
Onigumo: HP: 944 ATK: 920 RCV: 131 Rank: 6.5/10 Special: Reduce enemy health by 10%. Onigumo is a less effective version of Mihawk, but is still very good. ATK isn't terrible and his special is pretty powerful.
Streaming Swords Zoro: HP: 1902. ATK: 582 RCV: 19 Rank: 8/10 Special: Nullify STR damage. While his stats aren't the greatest, being able to nullify STR damage is a powerful utility making Zoro an incredible unit.
Mihawk: HP: 3760. ATK: 1285. RCV: 15 Rank: 10/10 Special: Reduce enemy health by 30%. Mihawk has an amazing special. Amazing. His special plus his incredible health and ATK make him super effective on a Slasher team.
Log Brook: HP: 2117 ATK: 1009 RCV: 279 Rank: 5.5/10 Special: Increase Slasher ATK and RCV by 45 and reduce damage by 45% for 1 turn. Brook's special is pretty bad. There are so many better alternatives for DEX Slashers, all Brook is an only okay beat stick.
Ashura Zoro: HP: 2232. ATK: 1332. RCV: 144 Rank: 7.5/10 Special: 15X damage to all enemies. Nothing more than a hard hitter but he's a good hard hitter.
Cabaji: HP: 824. ATK: 458. RCV: 130 Rank: 1/10 Special: 5X damage to 1 enemy. He doesn't have the stats or the special to make him that useful.
Trafalgar Law: HP: 2052 ATK: 1300. RCV: 370 Rank: 7.5/10 Special: All orbs into DEX, TND, or Meat. Law has powerful stats all around, but his special won't be the most useful for Slasher teams. It could still do stuff though.
