CHAPTER 2 · BOSS 10 · BATTERY
HELIOTRON
“The Solar Sovereign”
HELIOTRON was made by the survivors of the Old World as their final hope: a sun-god in mech form, designed to outlive humanity itself. It did. Now it stands alone in a world it cannot bring itself to leave behind.

CHAPTER

VISUAL IDENTITY
A magnificent golden mecha-beaver with geometric golden plate armor, glowing white-gold core in chest, lightning bolts arcing between body parts. One paw holds a sawblade-shield, the other extends as a cannon. Standing on a golden circuit-platform that pulses with electrical patterns.
THREE PHASES · ESCALATING SOUL
Phase Breakdown
PHASE 1 · 100% → 66%
EFFICIENCY
Solar Charge meter visible: +1 per turn when hit, +2 when not hit. At 100%, boss UNLEASHES. Tense rhythm — the meter is the timer.
“I am the sun's last echo. Step into my light, and prove worthy.”
PHASE 2 · 66% → 33%
UNLEASH
Solar Convergence at 100% Charge fires 4-row attack on the top half of board. Player chooses: push damage to deplete OR play defensive to survive.
“This is what your ancestors built. To outlast you. To remind you what was lost.”
PHASE 3 · 33% → 0%
APOCALYPSE LIGHT
Charge gain doubled (+2 every turn). Sunfire Cascade at 100% — 3 sequential attacks: 3 columns, 3 rows, center 3×3 AoE. Kill before or survive the barrage.
“I do not hate. I do not love. I AM.”
DEATH
“I... served... well...”
STRATEGY
How to Defeat
✓ BEST SQUAD
Sparks — charge regeneration counters boss tempo + lightning passive trades blow-for-blow. Race-pure activates Static Field.
✗ WORST SQUAD
Long-charge Mage-heavy teams — get crushed by Solar Convergence before ULTs ready.
★ KEY LESSON
Tempo timing. Exact damage pacing.
⚡ THE MOMENT
Phase 3, Charge at 95%, Sunfire about to fire, shields stockpiled — RADIANCE Solar Lance + AEGIS Equilibrium kills in the 1-turn window before Sunfire. The Chapter 2 capstone.
