Every ship you can fly, taken apart: signature skills and their 20-star evolution ladders, the milestone perks, the full upgrade bill, and where each one actually comes from.
A Fighter's base stats are a grade template — every same-grade ship starts identical (N 200 HP/100 ATK · R 400/100 · SR 600/150 · SSR 1,000/250, all at ×2 crit damage). What actually differentiates ships is the kit: a signature passive, four level-milestone perks, a 20-step star ladder that keeps evolving the signature, and — for the five newest SSRs — a hidden ×1.5 stat multiplier.
"Signature" is the ship's base passive. "At ★20" is the final form of that signature after the star ladder finishes evolving it. "Level perks" unlock at levels 20/40/60/80. "Grown +HP/+ATK" is everything the ship gains from all 80 levels plus all 20 stars — this is where grade (and the ×1.5 tier) actually pays out, because the bill for those upgrades is identical for every ship.
Each Fighter carries one signature skill — a summon, a special weapon, a survival trick. It doesn't stay static: of the 20 star-up steps, most are skill evolutions that push the signature's numbers, with a few flat "All attack +X%" steps mixed in. On top of that, four fixed level milestones (20/40/60/80) bolt on weapon-specific perks.
Worked example — Phantom's "Summon Mirror": the base skill summons a mirror fighter that inherits your barrage. The star ladder then raises the mirror's inherited attack 55% → 100% and its duration 15 s → 25 s across ★1–★20. A maxed Phantom effectively doubles your firepower for 25 seconds — a completely different ship from the one you unlocked.
The same pattern drives every SSR: Killer Hornet's hive wasps end at 300% attack, Conqueror gains a second Vulcan drone, Optimus Prime generates 2 extra power capsules.

Each of the 20 star-ups grants a concrete powerup (fighter_extra_attr → fighter_extra_skill): most steps evolve the signature skill's numbers, the rest are flat stat boosts. Pick a ship for its complete ladder — powerup text, the universal shard/Stars bill, and that ship's own per-step HP/ATK gains.
Leveling and starring cost exactly the same whether you're building the free starter or a ×1.5 SSR: the full ride is 2.85M Stars + 5,610 Alloy Plate for 80 levels, plus 1,520 of the ship's own shards + 6.04M Stars for 20 stars. Grade changes only the payout — Red Phantom's 80 levels grant +72,540 HP; Conqueror's identical-cost 80 levels grant +209,520. The price of power isn't the upgrade bill, it's acquiring the better chassis.
The complete attrLevels ladder — the cost columns are identical for every ship; the stat columns are the ship's cumulative HP/ATK at that level, one pair per stat group (the level curves are verified identical inside each group). SSR ×1.5 is the prestige tier (Conqueror, Thor, Destroyer, Optimus, Megatron).
The complete starLevels ladder — ★0 is the 10-shard activation step; stat columns are cumulative bonus HP/ATK from stars. Most steps also evolve the ship's signature skill (see "At ★20" in the roster).
Fighters drop as whole ships from crates (shards are for star-ups). The standard fighter crate rolls these odds:
Beyond the crates, three ships are direct purchases and four are walled into collab pools:
pvp_attack_rate of 2,000 — the arena re-bases attack so crate luck decides less in PvP than the raw numbers suggest. Crate keys, pity and per-crate odds live in Gacha & Odds.
