Save your summon points in DRAGON BALL Z DOKKAN BATTLE unless Metal Cooler directly fills a missing revival role required to clear specific Wicked Bloodline or Extreme PHY endgame stages. Summon points accumulate slowly at a fixed rate per summon, making direct redemptions an expensive commitment that should address clear progression bottlenecks rather than unplayed roster expansion.
Summon Point Exchange Criteria
Spend summon points on Metal Cooler only if your box meets narrow category requirements. If your Extreme teams already clear difficult stages or you focus primarily on Super-class rosters, save your currency for high-impact Carnival and Dokkan Festival leads featuring unconditional damage reduction, guard, or broad team support.
| Roster Condition | Recommended Action |
|---|---|
| Missing a core Wicked Bloodline revive unit | Redeem if actively tackling category Red Zone missions |
| Already own one copy (55% Hidden Potential) | Pass; save points for unowned Carnival LRs |
| Missing high-tier Extreme PHY units | Situational buy if Extreme Super Battle Road remains unfinished |
| Maining Super-class teams (Movie Heroes, Pure Saiyans) | Pass; preserve summon points for dual-category leaders |
Kit Mechanics and Battle Limitations
Metal Cooler provides reliable HP sustain, stat accumulation through taking hits, and a single-use revival mechanic when team health drops below critical thresholds. While these traits stabilize extended boss fights where incoming normal attacks deal manageable damage, his kit has distinct limitations in modern endgame content:
- Turn-One Vulnerability: Metal Cooler requires multiple hits received to build up his passive defense. Facing high-stat phase-one bosses can trigger his revival prematurely or cause a game over before he stacks.
- Slot 1 Danger: Placing him in Slot 1 before his passive defense builds is risky unless mitigated by damage-reduction items like Whis or Icarus.
- Burst Damage Weakness: Turn-start HP recovery manages chip damage across long battles, but it does not stop single-target Super Attacks that exceed your total maximum HP.
Positioning and Team Synergy
To use Metal Cooler effectively, deploy him in Slot 2 or Slot 3 during his opening turn. This positioning exposes him to secondary normal attacks, allowing him to stack his defensive passive safely while keeping him away from immediate lethal damage.
Metal Cooler performs best when linked with Wicked Bloodline and Terrifying Conquerors partners:
- LR Final Form Cooler: Shares key villain links that fix Ki requirements and provide shared defensive stats.
- Golden Frieza: Functions as a dedicated Slot 1 defender to absorb early heavy attacks, allowing Metal Cooler to operate safely in Slot 2. In turn, Metal Cooler’s start-of-turn healing helps sustain the high-HP thresholds required for certain Golden Frieza damage-reduction passives.
Banner Management and Next Steps
If you want Metal Cooler, do not chase him with Dragon Stones on banners where he is unfeatured or featured among low-value side units. The recommended approach is to summon only on high-value banners that improve your broader account, accumulate summon points naturally, and redeem Metal Cooler from the shop only when a specific Red Zone or Extreme Super Battle Road mission demands his revival utility.
