We are Apollo's Raiders, and this is our Jolly Rodger.
Crew Captain: Kenpachi Zaraki (Bleach)
I picked Zaraki because of a couple of reasons: He is a man of domineering strength and endurance, with the insatiable lust for battle that will guide our crew to prosperous heights. Zaraki will never be caught idle.
Secondly, with him at the helm, other crews will quake in fear at the sight of our jolly rodger and there will never come a time where there is even the threat of a mutiny.
1st Mate: Negi Springfield (Mahou Sensei Negima)
I pick Negi as the second-in command because of his brains and his tremendous magical abilities. He is able to use Magi Arebea, absorbing massive spells into his body to use their magical energies as boosters to his own fighting abilities. His Raiten Taisou form allows him to move with literal lightning speed, as well as call down huge spells with little or no incantation. He would command as much respect as Zaraki, and would be able to do the important planning.
Rest of Crew:
Tenten (Naruto) - Weapons Expert
Every good crew needs someone who can wield a weapon. Tenten is the absolute epitome of a weapons expert. She can even summon her own from the scroll she carries on her back. She'd hold us down on emergency weapons.
Tatsumi (Akame Ga Kill) - Guard
We've already got a lot of offensive power on the crew, so we need someone with significant defensive power to balance it out. Enter Tatsumi, with his amazing Incursio armor that not only augments his strength, but significantly increases his defense. It's nigh on impregnable, and we'll need that for some of our scraps.
Chrome Dokuro (Katekyo Hitman Reborn) - Thief
With her incredible powers of illusion and undying will to live, Chrome makes an ideal addition to the crew. It might be hard to convince Tsunayoshi to have one of his famiglia away from him, but I think he'll understand once he has a conversation with Zaraki...
Kaneki Ken (Tokyo Ghoul) - The Crazy One
Every crew needs a loose cannon, right? Someone who's not totally right in the head? Maybe? Well, we have one, and it's Kaneki Ken, the ghoul with problems aplenty.
Cana (Fairy Tail) - The Cook/Extra Muscle
Even if she has unidentified cooking skills, Cana would certainly make sure we always had booze on board. Sure, she might drink a bunch of it herself, but as long as there's enough to go around, that'll be okay. Booze is important for every seafaring pirate.
Izuku (Boku no Hero Academia) - The Rookie
Izuku is real earnest about his heroism. Given the members of this crew, most of them anyway, it will be good to have a strong moral compass on the team. We need someone to remind us where the line is, and not to cross it.
Kyubey (Puella Magi Madoka) - The Mascot
This evil little bastard... doesn't need explaining. He's the mascot for Apollo's Raiders
