Impact Usopp: HP: 1185. ATK: 669. RCV: 265 Rank: 5/10 Special: 2X PSY boost. Impact Usopp can double PSY ATK which is a pretty powerful utility, but that won't fit too well on a Shooter team. This usopp also suffers from crummy stats and the fact that another Usopp is one of the MVP's of the game.
Mr.8: HP: 1286. ATK: 433. RCV: 180. Rank: 2/10 Special: 5X damage to all enemies. Oh my gosh... All Mr. 8 has is health... Nevermind. He doesn't really have health. Don't use him.
Golden Pound Usopp: HP: 1080. ATK: 648. RCV: 144 Rank: 10/10 Special: Delay enemies by 3 turns. Crummy stats? Who cares! Golden Pound Usopp delays enemies for 3 turns with a special cooldown that maxes out at 10. Usopp is a MUST HAVE unit. He can go on any team and bring it to new heights.
Victoria Cindy: HP: 1402. ATK: 661. RCV: 478 Rank: 4/10 Special: All orbs into PSY or INT and damage all enemies. Cindry does suck from crummy stats (except for her RCV); however, she can change all of your orbs and do damage. Not the greatest, but can easily be outclassed as a Shooter.
Sogeking: HP: 1506. ATK: 690. RCV: 479 Rank: 5/10 Special: 15X damage to all enemies and delay enemies by 3 turns. I don't know why Usopp evolves into Sogeking because they're clearly not the same person, but Usopp should've just stayed Usopp because Sogeking's longer special cooldown is not worth the crummy stat boost.
Franky: HP: 2453. ATK: 1032. RCV: 198 Rank: 7.5/10 Special: Switch orbs twice. Franky has decent stats and his special allows you to move around orbs which can be awesome to get the orbs you want. Franky is definitely a considerable unit for a Shooter team.
