Depends on use actually. Although Pirate is good, it's effect is knockback while Viking is strong against red and gains area attack when you get the trueform (save up the catfruit and EXP for that), you can always add Fish Cat/Crazed Fish Cat and Titan to the fray or other units that can help with Reds.

So not necessarily need the three unless it's a big stack of Bores.
