Secondary Fire: Aqua Burst
Water projectile that bursts on landing, dealing splash damage (~70 on hit) and slight enemy knockback.

Charge‑based cooldown (3 charges) makes it useful for zoning or softening foes

Ability: Hide and Seek
Jeff dives underground, speeding up by ~60%, gradually regenerating health (~35/s), and reducing his hitbox.

Ultimate: It's Jeff!
Jeff dives underground then emerges as a huge shark that swallows allies and enemies in range (~6s duration).

Allied players heal rapidly if inside (225/s, bonus cap ~150), while enemies take damage (~25/s).

Jeff can carry enemies around and spit them out—for instance, off a ledge for a potential wipe!

🧠 Play Tips
Keep your beam targeting allies while you're safely tucked away.

Drop Healing Bubbles in predicted team-combat zones for easy pickups.

Use Hide and Seek defensively or to flank.

Time It's Jeff! when enemies are clustering—bonus kills come from spitting them off ledges.

Pair with a tank like Hulk or Groot to stay alive and heal effectively.

Coordinate team-up synergy: Luna Snow for slows; Groot for resilience and elevated attacks
